DME As An Alternative Fuel Produced From CO2-enhanced Gasification Of Biomass

It was a tragic irony of fate that Ronald Holroyd should have died on 29 September 1973, just on the eve of the energy crisis which suddenly and dramatically focused the attention of the Western World on the urgency of finding an alternative fuel to Middle East oil, which had almost overnight become scarce and expensive. For the outstanding work of Holroyd s career, before and during the last war, was in attempting to provide a liquid fuel based on coal, and, apart from a wartime success when availability was the paramount consideration, these attempts failed largely because Middle East oil was plentiful and cheap. Ronald Holroyd was born at Horbury, near Wakefield, on 26 April 1904, the son of Sykes and Florence Holroyd. His father started work as a boy of eleven at the firm of Sykes Bros, sporting goods’ manufacturers at Horbury, and attended evening classes at Wakefield where he proved to be a first class student and was subsequently invited to teach in the evenings. This work increased and as a result he was invited to join the full time staff of the Miming and Technical School at Barnsley, where he taught mathematics, mechanics and technical drawing. He had a quick and lively mind which remained with him until he died, a few years ago, at the age of 92, still absorbed in mathematics. Florence Holroyd, his wife, was a teacher and there is no doubt that Ronald Holroyd owed a great deal to their deep interest in educational matters, and to their encouragement in his formative years.

The Impact

Among the alternative fuels existing for spark-ignition engines, ethanol is considered worldwide as an important renewable fuel when mixed with pure gasoline because of its favorable physicochemical properties. An in-depth and updated investigation on the issue of CO and HC engine out emissions related to use of ethanol/gasoline fuels in spark-ignition engines is therefore necessary. Starting from our experimental studies on engine out emissions of a last generation spark-ignition engine fueled with ethanol/gasoline fuels, the aim of this new investigation is to offer a complete literature review on the present state of ethanol combustion in last generation spark-ignition engines under real working conditions to clarify the possible change in CO and HC emissions. In the first section of this paper, a comparison between physicochemical properties of ethanol and gasoline is examined to assess the practicability of using ethanol as an alternative fuel for spark-ignition engines and to investigate the effect on engine out emissions and combustion efficiency. In the next section, this article focuses on the impact of ethanol/gasoline fuels on CO and HC formation. Many studies related to combustion characteristics and exhaust emissions in spark-ignition engines fueled with ethanol/gasoline fuels are thus discussed in detail. Most of these experimental investigations conclude that the addition of ethanol with gasoline fuel mixtures can really decrease the CO and HC exhaust emissions of last generation spark-ignition engines in several operating conditions.
