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 2016-07-22 with total page pages. Available in PDF, EPUB and Kindle. 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 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Through the mid-1980s, Air Products has brought the liquid phase approach to a number of other synthesis gas reactions where effective heat management is a key issue. In 1989, in response to DOE's PRDA No. DE-RA22-88PC88805, Air Products proposed a research and development program entitled ''Synthesis of Dimethyl Ether and Alternative Fuels in the Liquid Phase from Coal Derived Syngas.'' The proposal aimed at extending the LPMEOH experience to convert coal-derived synthesis gas to other useful fuels and chemicals. The work proposed included development of a novel one-step synthesis of dimethyl ether (DME) from syngas, and exploration of other liquid phase synthesis of alternative fuel directly from syngas. The one-step DME process, conceived in 1986 at Air Products as a means of increasing syngas conversion to liquid products, envisioned the concept of converting product methanol in situ to DME in a single reactor. The slurry reactor based liquid phase technology is ideally suited for such an application, since the second reaction (methanol to DME) can be accomplished by adding a second catalyst with dehydration activity to the methanol producing reactor. An area of exploration for other alternative fuels directly from syngas was single-step slurry phase synthesis of hydrocarbons via methanol and DME as intermediates. Other possibilities included the direct synthesis of mixed alcohols and mixed ethers in a slurry reactor.

This book was released on 1993 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the DOE-sponsored contract Synthesis of Dimethyl Ether and Alternative Fuels in the Liquid Phase from Coal-Derived Syngas'' experimental evaluations of the one-step synthesis of alternative fuels were carried out. The objective of this work was to develop novel processes for converting coal-derived syngas to fuels or fuel additives. Building on a technology base acquired during the development of the Liquid Phase Methanol (LPMEOH) process, this work focused on the development of slurry reactor based processes. The experimental investigations, which involved bench-scale reactor studies, focused primarily on three areas: (1) One-step, slurry-phase syngas conversion to hydrocarbons or methanol/hydrocarbon mixtures using a mixture of methanol synthesis catalyst and methanol conversion catalyst in the same slurry reactor. (2) Slurry-phase conversion of syngas to mixed alcohols using various catalysts. (3) One-step, slurry-phase syngas conversion to mixed ethers using a mixture of mixed alcohols synthesis catalyst and dehydration catalyst in the same slurry reactor. The experimental results indicate that, of the three types of processes investigated, slurry phase conversion of syngas to mixed alcohols shows the most promise for further process development. Evaluations of various mixed alcohols catalysts show that a cesium-promoted Cu/ZnO/Al[sub 2]O[sub 3] methanol synthesis catalyst, developed in Air Products' laboratories, has the highest performance in terms of rate and selectivity for C[sub 2+]-alcohols. In fact, once-through conversion at industrially practical reaction conditions yielded a mixed alcohols product potentially suitable for direct gasoline blending. Moreover, an additional attractive aspect of this catalyst is its high selectivity for branched alcohols, potential precursors to iso-olefins for use in etherification.

This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Available in PDF, EPUB and Kindle. Book excerpt: The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.

This book was released on 2011-11-21 with total page 1088 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.
