OSTI ID:5840996
The Solvolysis Coal Liquefaction Process is a Short-Contact-Time Two-Stage Liquefaction Process (SCT-TSL), which consists of the first stage of a noncatalytic SCT reaction without molecular hydrogen and the second stage of catalytic hydrocracking of SRC after deashing. The applicability of the process to a bituminous coal was studied based on the analysis of SCT reaction mechanism. The evaluation method of solvent quality has been established. The 0.1 t/day Process Development Unit (PDU) was operated to establish the process using a subbituminous coal in Australia and a bituminous coal in USA. By the PDU operation, high oil yield more than 50 wt% (daf) was attained with low hydrogen consumption for both coals.
