Title:
AN INTEGRATED COAL LIQUEFACTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2008/083600
Kind Code:
A1
Abstract:
An integrated coal liquefaction process includes a coal gasification step (201),
a Fischer-Tropsch synthesis step (203), a coal carbonylation step (207) and
a coal direct liquefaction step (209), wherein the carbon monoxide consumption
during water gas shift conversion reaction in the Fischer-Tropsch synthesis
step (203) is less than 5%. The carbon monoxide in the synthesis gas produced from
the coal gasification step (201) or t he carbon monoxide in the tail gas produced
from the synthesis gas converting step (203) are used in the coal carbonylation
step (207). The pretreated coal from the coal carbonylation step (207) is subjected
to hydrogenation liquefaction in the coal direct liquefaction step (209). Applying
recovered carbon monoxide to carbonylation reaction of feed coal can reduce
the carbon dioxide emission of the liquefaction process, and simultaneously
increase the utilization rate of carbon.
