In order to analyze the effect of hydrogen rich gas addition (HRG) on lean burn engine’s thermal efficiency and emission, an experimental research was conducted on a gasoline direct injection (GDI) engine using definite fraction of HRG. The results showed that HRG addition could significantly extend the lean operation limit, improve the engine’s lean burn ability, and decrease burn duration. HR...

soil in which they were found but are the remains of animals living in the sea on whose bed the soil (sediment) was deposited. The latter paper is a summary of a projected further work which unfortunately never appeared. It is the Prodromus that contained the first statement of the Law of Superposition; and much more. 'If, in a certain stratum, we find great abundance of rushes, grass, pine con...

The use of standard gas composition measurement techniques, such as gas chromatography, in large scale solid oxide fuel cells (SOFC’s) operating at high temperatures can be both complex and time consuming. One of the main constraints is the necessity to condense out the water vapour present in the gas streams prior to measurement in the Gas Chromatograph (GC). True gas compositions can only be ...

ibn al-moqaffa, an iranian thinker and reformer lived in the era when people suffered from tyranny. he had well realized the root of people's problem which he attributed to the political regime. he was the one who believed that the progress of common men depends on the progress of nobles and their progress is not possible without their leader's progress. the society in those days was ...

The present work deals with hydrogen generation from JP8 reformation and clean-up of the reformate to produce PEMFC quality hydrogen. The fuel processor has reformer, postformer, water gas shift reactors, H2S removal, preferential CO oxidation, and CO2 removal stages. The processor also incorporates a final adsorbent fuel filter that can efficiently remove ppm level impurities that may poison t...

Glycerin is a potential feedstock for hydrogen production because one mole of glycerin can produce up to four moles of hydrogen. In addition to glycerin, several potential biorenewable feedstocks, such as triglycerides and their derivatives, could be used for hydrogen production. The major challenge in using such feedstocks in a hydrogen-producing reformer is atomizing these viscous feedstocks ...
