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.

Download or read book Engine Emissions written by Donald J. Patterson and published by Springer. This book was released on 1973 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, emissions from transportation engines have been studied widely because of the contribution of such engines to atmospheric pollution. During this period the amounts of pollutants emitted, the mechanism of their formation, and means of controlling emissions have been investigated in industrial and government laboratories, as well as at universities. The results of these investigations have generally been published as individual articles in journals, transactions, meeting proceedings, and, frequently, in company reports. This proliferation of technical information makes it difficult for workers in the field to keep abreast of all developments. For this reason, the editors felt the need for a book which would survey the existing state of knowledge in wide, albeit selected areas, and would provide a guide to the relevant literature. This book is intended to fulfill this function. It is recognized that all aspects of transportation engine emissions cannot be explored in a single volume. In this book attention is focused primarily on sources and mechanisms of emission formation within the combustion process, and on measurement techniques. Beyond this objective, no re strictions were placed on the authors. Within the framework of the general theme each author has been free to treat his subject as he saw fit. The editors have not strived to replace by uniformity the highly personal and attractive divergences of style. Considerable efforts were made, however, to ensure clarity and minimum overlap between the chapters.

Available in PDF, EPUB and Kindle. Book excerpt: A key topic of many technical discussions has been the development of alternative fuels to power the compression ignition engine. Reasons for this include the desire to reduce the dependency on petroleum-based fuel and, at the same time, to reduce the particulate matter (PM) and NOx emissions. Also, there has been interest generated in the diesel engine because of the reduction in greenhouse gases that has been proposed during the 2008-2012 time frame in Europe and the regulations that affect diesel engines in the United States.

This book was released on 2023-02-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single cylinder diesel engine is an internal combustion engine where fuel is ignited by compressing air in a combustion chamber. In recent years, there has been growing interest in using alternative fuels in diesel engines to reduce environmental impact and promote sustainability. One such alternative fuel is coconut biodiesel, which is derived from coconut oil and has been found to have good combustion properties. To enhance the performance and reduce the emissions of coconut biodiesel, researchers have explored the use of fuel additives. These additives can improve the properties of the fuel and enhance its combustion characteristics. The use of additive blends with coconut biodiesel has shown promise in reducing emissions and improving engine performance. Studies have investigated the effects of using different types and concentrations of additives in coconut biodiesel blends, such as antioxidants, surfactants, and cetane improvers. These studies have shown that the use of additive blends can reduce emissions of pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM), while also improving engine power and efficiency. The use of coconut biodiesel and additive blends in diesel engines has several advantages, including the use of a renewable and locally sourced fuel source, reduced emissions of harmful pollutants, and improved engine performance. However, further research is needed to optimize the use of these fuels in diesel engines and ensure their long-term viability and sustainability. Overall, the use of single cylinder diesel engines with coconut biodiesel and additive blends shows promise as a more sustainable and environmentally friendly alternative to traditional diesel fuels. Particulate matter (PM) or smoke emission and oxides of nitrogen (NOx emissions) are the two important harmful emissions in diesel engine. Fuel companies and the researchers around the world are devoted to reduce such emissions with different ways. Fuel modification, modification of combustion chamber design and exhaust after treatments are the important means to alleviate such emissions. In this context, engine researchers are hunting for suitable alternative fuels to the diesel engine. Among different alternative fuels, oxygenated fuel is a kind of alternative fuel. Diethylene glycol dimethyl ether (DGM), dimethoxy methane (DMM), dimethyl ether (DME), diethyl ether (DEE), methyl tertiary butyl ether (MTBE), dibutyl ether (DBE), dimethyl carbonate (DMC), methanol, ethanol and Triacetin (anti-knocking agent for gasoline) have played their role to reduce diesel emissions. These fuels can either be used as a blend with conventional diesel/biodiesel fuel or as an additive or as a neat fuel. The presence of oxygen in the fuel molecular structure plays an important role to reduce PM and other harmful emissions from diesel engine.

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.

Book excerpt: The world at present is mainly dependent upon petroleum-derived fuels for meeting its energy requirement. However, perturbation in crude prices, which concerns about long-term availability of these fuels coupled with environmental degradation due to their combustion, has put renewable alternative fuels on the forefront of policy maker,Äôs agenda. The diesel engines are considered workhorse in the global economy due to better thermal efficiency, ruggedness, and load carrying capacity. They, however, are also the main contributor to air pollution as they emit more oxides of nitrogen, suspended particulate matter as compared to gasoline engines. The most potential fuel either to supplement or to substitute diesel is biodiesel, butanol, producer gas, dimethyl ether, hydrogen, and so on. This chapter presents the developments about the use of alternative fuels in diesel engines. The exhaustive literature has evolved the main trends in the development of alternative fuels around the world. The chapter also describes the research directions on production and use of alternative fuels in off-road and transport vehicles powered by diesel engines.

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."

Book excerpt: This is a well known fact that the resources of mineral oils are depleting day-by-day, and the cost of exploration of the remaining reserves is bound to escalate. Moreover, the burning of fossil fuels increases the level of carbon-dioxide in the atmosphere causing the 'Green House' effect. In this context, a viable and sustainable alternative fuel is necessary to cater to a large fleet of automobiles across the world. The advent of bio-diesel has come to the rescue in such a warranting situation. Efforts are being made to streamline the systems to produce bio-diesels at economically viable rates and apply them in running the diesel engines in lieu of petro-diesel. And the present study is an attempt in this direction. It seeks to exploit non-edible oil plants, especially Jatropha, mahua and palm, to replace diesel oil usage in the conventional diesel engines. Providing transesterification procedure for all the three non-edible oils, it deals with the heat release rate calculations based on the pressure data collected in the combustion chamber. It also extends discussion on the instrumentation and experimentation, as well as the results of the findings.
