ABSTRACT:
This invention generally relates to short residence time decomposition and volatilization of coal to produce liquid co-products, including petroleum substitutes and chemical feedstocks, while minimizing production of char and gas without utilization of external hydrogen, that is, hydrogen other than that contained in the coal feedstock. The invention more particularly relates to an improved partial coal liquefaction process for economically producing petroleum substitutes and chemical feedstocks from coal by a refining process employing short residence time vaporization and hydrogen conservation.
