Hydrocracking of vacuum residue using a combination catalyst system of acti
ve carbon with iron, either in the form of iron impregnated or the mixture
with pyrite, was studied under a relatively low hydrogen pressure of 10 MPa
. This catalytic hydrocracking system successfully restricted the formation
of asphaltene and suppressed coke formation at higher conversions. Hydrode
metallization (HDM) and hydrodesulfurization (HDS) were also effectively ac
hieved.
Active carbon materials with various mesopore structure were evaluated as t
he catalyst component. Mesopore-richer active carbon adsorbed asphaltene mo
re selectively and suppressed coke formation more effectively. The effectiv
eness of the catalyst system was analyzed by a kinetic study of the hydrocr
acking reactions based on a lumping model.
