Abstract
Presents
a study of pre-cracking of heavy oils on a typical fluid catalytic cracking
catalyst. Researchers examined the role
of various factors, including those of zeolite, thermal reactions, and active
matrix. Results suggest that zeolite (REUSY) plays a leading role in
pre-cracking. Its contribution always accounts for more than 50%. In
highlighting the remarkable effect of zeolite, authors propose a new
hypothetical reaction route for the consideration of zeolite internal surface:
the relay of active sites.
The contributions of thermal reactions and active matrix change with
the contents of aromatic components in different feeds. The active matrix is
effective in pre-cracking large hydrocarbon compounds with aromatic rings. Its
contribution increases with the aromaticity of the feed.
