Ethanol is able to replace naphtha in two of its major usages, as raw material for ethylene production and as fuel for Otto engines. This possibility raises the question of value - or opportunity cost - of ethanol. Ethanol's economic value as a fuel is that value which equals the cost of the fuel consumed by a given vehicle travelling a given distance. In each case, unblended gasoline, a gasoline and ethanol blend or hydrated alcohol alone are the alternative fuels used. Ethanol's economic value as feedstock for producing ethylene is defined as that which makes the revenue from the ethylene derived from alcohol equal to the total revenue of products resulting from thermal cracking of 1 m/sup 3/ of naphtha. In this paper it is shown that ethanol's highest value corresponds to its use as hydrated alcohol feedstock for ethylene production. However, present tax laws and subsidies favor ethanol fuel use. 4 refs.
