Book excerpt: Bachelor Thesis from the year 2015 in the subject Chemistry - Bio-chemistry, grade: 1,0, RWTH Aachen University (Institut fur Systemverfahrenstechnik), language: English, abstract: Increasing global demand for fossil fuels makes the development of environmentally sustainable diesel-substitutes indispensable. Over the last decades, the production of dimethyl ether (DME) as alternative fuel has received increasing attention. The majority of ongoing research, however, still focuses on DME production from fossil resources. This thesis presents a single-step process for DME production from biogas which was designed following the hierarchical design method of Douglas. Process simulations were carried out in Aspen Plus for different biogas compositions. Economics estimated based on energy and feedstock cost showed that DME production is still twice as expensive as diesel production. On the other side, GHG emissions calculated including literature data on CO2 emissions of biogas production revealed a promising net reduction in CO2 emissions by 9 to 57% compared to diesel."

This book was released on 2013-06-10 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing awareness of the environmental issues forces a strong drive towards the development of new, sustainable processes for renewable energy production. Likewise, the economic issues related to the increasing prices of crude oil, and its derivatives lead to the recognition of advantages of alternative fuels, thus a significant interest in biomass-derived, synthetic fuels is observed. Among various thermo-chemical conversion processes, biomass gasification is one of the most effective, efficient and sustainable solutions to the production of renewable energy. It provides a gaseous fuel, composed mainly of carbon monoxide and hydrogen, suitable to produce chemicals, heat, and energy. In particular, syngas can be used to obtain methanol (MeOH) and dimethyl ether (DME), both energy carriers of great interest for many advanced energy applications. The herein presented work provides the reader with a comparison of the technicalities as well as economics of methanol and DME production from biomass-derived syngas, by different pathways. For that purpose a process simulation by means of the ChemCAD® commercial code was used. The developed simulation strategies include both, optimization of the kinetic models and unique solution of fuel refinement.

Download or read book Conceptual Process Design and Economics for the Production of High-octane Gasoline Blendstock Via Indirect Liquefaction of Biomass Through Methanol/dimethyl Ether Intermediates written by and published by . This book was released on 2015 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes in detail one potential conversion process for the production of high-octane gasoline blendstock via indirect liquefaction of biomass. The processing steps of this pathway include the conversion of biomass to synthesis gas via indirect gasification, gas clean-up via reforming of tars and other hydrocarbons, catalytic conversion of syngas to methanol, methanol dehydration to dimethyl ether (DME), and the homologation of DME over a zeolite catalyst to high-octane gasoline-range hydrocarbon products. The current process configuration has similarities to conventional methanol-to-gasoline (MTG) technologies, but there are key distinctions, specifically regarding the product slate, catalysts, and reactor conditions. A techno-economic analysis is performed to investigate the production of high-octane gasoline blendstock. The design features a processing daily capacity of 2000 tonnes (2205 short tons) of dry biomass. The process yields 271 liters of liquid fuel per dry tonne of biomass (65 gal/dry ton), for an annual fuel production rate of 178 million liters (47 MM gal) at 90% on-stream time. The estimated total capital investment for an nth-plant is $438 million. The resulting minimum fuel selling price (MFSP) is $0.86 per liter or $3.25 per gallon in 2011 US dollars. A rigorous sensitivity analysis captures uncertainties in costs and plant performance. Sustainability metrics for the conversion process are quantified and assessed. The potential premium value of the high-octane gasoline blendstock is examined and found to be at least as competitive as fossil-derived blendstocks. A simple blending strategy is proposed to demonstrate the potential for blending the biomass-derived blendstock with petroleum-derived intermediates. Published 2015.

This book was released on 2018-07-30 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technischer Bericht aus dem Jahr 2018 im Fachbereich Energiewissenschaften, , Veranstaltung: Erneuerbare Treibstoffe, Sprache: Deutsch, Abstract: DME known as dimethyl ether, is a well known chemical substance, the simplest ether, with the chemical structure CH3-O-CH3, consisting of one oxygen atom, two carbon atoms, and six hydrogen atoms. If we us Dimethyl ether as fuel, we recognize, that this fuel brings in one oxygen atom and has six hydrogen atoms. If we compare with methanol (CH3-OH), which has only four hydrogen atoms, dimethyl ether as simplest ether can also be seen as hydrogen carrier. The thermodynamic properties of Dimethyl ether, show that dimethyl ether is liquid at room temperature T=25°C and a pressure of p=6 bar. It is well known that dimethyl ether can be used as an substitute of fossil Diesel fuel, as a synthetic formed Diesel substitute, with highly advanced combustion properties and very low emissions in carbon monoxide(CO), dust and soot and nitrogen oxide(NO2). It easy to handle with the well known LPG (liquid propane gas) technology and can be easily and cheap implemented into heavy Diesel engines. The application of dimethyl ether is wide: transportation, agriculture, civil and rural hotel sector.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dimethyl-ether (DME) is considered to be one of the most promising, renewable alternative fuels. This thesis studies, develops, analyzes and assesses the performance of three dimethyl-ether production integrated systems, where dimethyl-ether is produced from carbon dioxide and renewable hydrogen. The three systems are fully operated by waste heat and renewable energy. The first system consists of a proton exchange membrane electrolyzer system, carbon capturing system and heat recovery from cement furnace, methanol synthesis system and dimethyl-ether synthesis system. The second system consists of a solar heliostat field, solid oxide steam electrolyzer, carbon capturing and heat recovery system from steel furnace, methanol synthesis system and dimethyl-ether synthesis system. The third system consists of gas turbine cycle, Cu-Cl thermochemical hydrogen production cycle, carbon capturing system and heat recovery from gas turbine exhaust gas, methanol synthesis system, dimethyl-ether synthesis system and multi-effect desalination system. Modeling studies and simulations are performed using both Aspen Plus, and Engineering Equation Solver software packages. These three systems are thermodynamically assessed based on energy and exergy efficiencies. The overall system's energy and exergy efficiencies resulted in 40.46 % and 52.81 for the first system, 28.75% and 32.54% for the second system, and 39.72% and 55.2 % for the third system.

Book excerpt: Technischer Bericht aus dem Jahr 2018 im Fachbereich Energiewissenschaften, Note: 1, , Veranstaltung: Erneuerbare Treibstoffe, Sprache: Deutsch, Abstract: At the begin of the 20th century C. Weizmann studied methods for substitution of petroleum, the most important fuel at this time beside coal. His famous work led to the patent about the ABE process [1], producing acetone by clostridium acetobutylicum and beside acetone, butanol (C4 alcohol) and ethanol (C2 alcohol) are created. (Historical: acetone could be used in military applications). The ideas [1] were very fruitful, but the world wars and the huge amount crude oil in Texas started a new period of economic development and growth of the world trade and business. At the end of the 20th century we recognized the limitation of the raw materials. Additional the Diesel technology reached a satisfied region in development the pollution of the exhaust gas. 2005 VOLVO started a project replacing fossil Diesel by Dimethyl ether [2]. This was so successful and it was the prolongation of a development done in 2008 by VOLVO [2]. At this time no heavy truck company was interested. At the end of the project VOLVO entered with the DME trucks successful the US market. The next company testing DME was MACK TRUCK followed two years later FORD. This was the birth of a new market. DME has the advantage to be monomolecular fuel, which can be easy supplied to existing and new Diesel engines. Using the known common rail for DME injected into the combustion chamber of engines it changes the phase from liquid to gas. This important property leads to a dramatic reduction of exhaust gas pollution in carbon monoxide, nitrogen oxide and soot, fine particles.
Book Synopsis Synthesis of Dimethyl Ether and Alternative Fuels in the Liquid Phase from Coal-derived Synthesis Gas by :
Download or read book Synthesis of Dimethyl Ether and Alternative Fuels in the Liquid Phase from Coal-derived Synthesis Gas written by and published by . This book was released on 1992 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the DOE-sponsored contract for the Synthesis of Dimethyl Ether (DME) and Alternative Fuels in the Liquid Phase from Coal- Derived Syngas, the single-step, slurry phase DME synthesis process was developed. The development involved screening of catalyst systems, process variable studies, and catalyst life studies in two 300 ml stirred autoclaves. As a spin-off of the Liquid Phase Methanol (LPMEOH*) process, the new process significantly improves the syngas conversion efficiency of the LPMEOH process. This improvement can be achieved by replacing a portion of methanol catalyst with a dehydration catalyst in the reactor, resulting in the product methanol being converted to DME, thus avoiding the thermodynamic equilibrium constraint of the methanol reaction. Overall, this increases syngas conversion per-pass. The selectivity and productivity of DME and methanol are affected by the catalyst system employed as well as operating conditions. A preferred catalyst system, consisting of a physical mixture of a methanol catalyst and a gamma alumina, was identified. An improvement of about 50% in methanol equivalent productivity was achieved compared to the LPMEOH process. Results from the process variable study indicate that higher pressure and CO[sub 2] removal benefit the process significantly. Limited life studies performed on the preferred catalyst system suggest somewhat higher than expected deactivation rate for the methanol catalyst. Several DME/methanol mixtures were measured for their key properties as transportation fuels. With small amounts of DME added, significant improvements in both flash points and Reid Vapor Pressure (RVP) were observed over the corresponding values of methanol alone.

Thermochemical Research Pathway to High-Octane Gasoline Blendstock Through Methanol/Dimethyl Ether Intermediates written by and published by . This book was released on 2015 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was developed as part of the U.S. Department of Energy's Bioenergy Technologies Office's (BETO's) efforts to enable the development of technologies for the production of infrastructure-compatible, cost-competitive liquid hydrocarbon fuels from lignocellulosic biomass feedstocks. The research funded by BETO is designed to advance the state of technology of biomass feedstock supply and logistics, conversion, and overall system sustainability. It is expected that these research improvements will be made within the 2022 timeframe. As part of their involvement in this research and development effort, the National Renewable Energy Laboratory and the Pacific Northwest National Laboratory investigate the economics of conversion pathways through the development of conceptual biorefinery process models and techno-economic analysis models. This report describes in detail one potential conversion process for the production of high-octane gasoline blendstock via indirect liquefaction of biomass. The processing steps of this pathway include the conversion of biomass to synthesis gas or syngas via indirect gasification, gas cleanup, catalytic conversion of syngas to methanol intermediate, methanol dehydration to dimethyl ether (DME), and catalytic conversion of DME to high-octane, gasoline-range hydrocarbon blendstock product. The conversion process configuration leverages technologies previously advanced by research funded by BETO and demonstrated in 2012 with the production of mixed alcohols from biomass. Biomass-derived syngas cleanup via reforming of tars and other hydrocarbons is one of the key technology advancements realized as part of this prior research and 2012 demonstrations. The process described in this report evaluates a new technology area for the downstream utilization of clean biomass-derived syngas for the production of high-octane hydrocarbon products through methanol and DME intermediates. In this process, methanol undergoes dehydration to DME, which is subsequently converted via homologation reactions to high-octane, gasoline-range hydrocarbon products.
