Vegetable Fuel Potential.
Abstract
The possible contribution to Defence fuels from vegetable sources is considered. Only two categories, ethyl alcohol from fermentation of carbohydrate material and vegetable oils directly from oil crops, can currently be produced with present technology in sufficient amounts to contribute to energy requirements. Liquid hydrocarbons from tree and shrub crops or microorganisms have not been produced in sufficient quantity to carry out even short term engine trails. Ethyl alcohol is an effective gasoline extender for spark ignition engines, but these are a minor part of Defence power units. Vegetable oils may be directly substituted for middle distillate fuels, but a number of technical difficulties are outlined. Chemical reaction of the vegetable oils with ethyl alcohol produces a liquid fuel which has similar physical properties to petroleum distillate. Experiment and theoretical evidence suggests these vegetable oil esters have better combustion properties in compression ignition power units than petroleum distillate. Significant amounts could be produced in a strategic situation within a short lead time. Additional keywords: Australia; esters; Fuel alcohol. (Author)
