Title:
HYDROGENATION PROCESS FOR COAL DIRECT LIQUEFACTION CIRCULATION SOLVENT
Document Type and Number:
WIPO Patent Application WO/2007/131437
Kind Code:
A1
Abstract:
A hydrogenation process for brown coal direct liquefaction circulation solvent
comprises two reactors, the first of which is mainly filled with protecting catalyst
with lower hydrogenation activity and the second of which is primarily filled
with main catalyst with higher hydrogenation activity, which forms a catalyst
grading suitable for a balanced hydrogenation/dehydrogenation reaction for
the solvent. Through the process, all compounds in the hydrogenated solvent
can reach even degree of incomplete saturation in molecular structure, which
improves transferable hydrogen content of molecules, accordingly the free
hydrogen- (-H) released by circulation solvent can meet the need of hydrogen
consumption of direct liquefaction of brown coal. The process can simplify the
industrial process of direct liquefaction and solvent hydrogenation, reduce
the device requirement, and save investment and operating cost.
