Comprehensive Utilization of Oil Shale and Prospect Analysis

As a kind of fossil fuels, oil shale has earn more and more attention with the soaring of international oil price. The calorific capacity of the oil shale is only inferior to that of the coal. Oil shale can be exploited to extract oil and gas by retorting and power generation by direct combustion. Shale oil, a synthetic crude oil which was produced by low-temperature retorting of oil shale may be used as fuel oil directly, also may be transformed as the gasoline, the diesel oil by further treatment. Coal gas and semi-coke are the by-product of oil shale production after low-temperature retorting which can be used as power plant fuel, the oil shale ash may be used as the building materials and soil fertilization matter. The oil shale retorting, the refinery oil, the semi-coke combustion power generation and the ash residue utilization organic union in the together theory realizes the comprehensive utilization of non-solid waste emissions finally. Comprehensive utilization of oil shale resources not only makes up the petroleum shortage but also phases down environmental pollution. Furthermore, circulation economic efficiency, the environmental benefit and the social efficiency are enhanced obviously. (C) 2012 Published by Elsevier Ltd.
