Abstract
Researchers
introduced macro-mesoporosity red mud (RM) using polystyrene and Pluronic F-127
as co-templates in to improve the catalytic performance of RM for slurry-phase
hydrocracking of vacuum residue. They characterized the resulting
macro-mesoporous red mud (Ma-RM) catalysts and applied them to the slurry-phase
hydrocracking of vacuum residue at 490°C for 2 hours. Comparative reaction
tests showed that Ma-RM exhibited better catalytic behavior for the VR
hydrocracking compared to activated RM without macropores.
Ma-RM successfully suppressed coke formation and increased liquid
yield in products distribution. The macroporous structure of Ma-RM was connected
by mesopores containing active sites for hydrogenation. The presence of a
macro-mesoporous structure enhanced hydrogenation over the catalysts.
