Alcohols and Other Oxygenates as Motor Fuels

Alcohols and other low molecular weight oxygenates are known to be potentially valuable gasoline substitutes. While these are generally of interest in relation to the long-term need to secure future motor fuel supplies, there is a more urgent need for substitutes which will improve the octane rating of unleaded fuels. For environmental reasons, oxygenates including alcohols may be preferred to ...

Microbial‐based motor fuels: science and technology

The production of biofuels via microbial biotechnology is a very active field of research. A range of fuel molecule types are currently under consideration: alcohols, ethers, esters, isoprenes, alkenes and alkanes. At the present, the major alcohol biofuel is ethanol. The ethanol fermentation is an old technology. Ongoing efforts aim to increase yield and energy efficiency of ethanol production...

The Major Metabolic Fuels

organized work. It is not surprising, therefore, that the active groups of the enzymes should only be capable of acting in association with a carrier of a given structure. For, orderly biological processes are unthinkable without presupposing structure, and it is therefore out of the question that any living constituent of protoplasm could consist of structureless, fluid, independently displace...

Fuels and Furnaces

The subject matter of this paper, if treated in the general sense, covers an extremely wide field to which it is impossible to do justice in the time allocated. It is even difficult to cover the subject adequately if we confine ourselves only to the furnace design of bagasse fired sugar mill boilers. I therefore intend to give a short summary of past and present bagasse furnace designs and cove...
