ABSTRACT:
This invention generally relates to co-production of petroleum substitutes, chemical feedstocks and methanol, 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 refining process for economically producing petroleum substitutes and chemical feedstocks and hot char from coal by a refining process employing short residence time vaporization and hydrogen conservation and subsequently gasifying the hot char to syngas for production of methanol.
