| description | The catalytic cracking of palm oil was
conducted in a fixed bed micro-reactor over HZSM-5,
zeolite and ultrastable Y (USY) zeolite catalysts. The
objective of the present investigation was to study the
effect of cracking reaction variables such as
temperature, weight hourly space velocity, catalyst pore
size and type of palm oil feed of different molecular
weight on the conversion, yield of hydrocarbons in
gasoline boiling range and BTX aromatics in the
organic liquid product. Statistical Design of Experiment
(DOE) with 24 full factorial design was used in
experimentation at the first stage. The nonlinear model
and Response Surface Methodology (RSM) were
utilized in the second stage of experimentation to obtain
the optimum values of the variables for maximum yields
of hydrocarbons in gasoline boiling range and
aromatics. The HZSM-5 showed the best performance
amongst the three catalysts tested. At 623 K and
WHSV of 1 h-1, the highest experimental yields of
gasoline and aromatics were 28.3 wt.% and 27 wt.%,
respectively over the HZSM-5 catalyst. For the same
catalyst, the statistical model predicted that the optimum
yield of gasoline was 28.1 wt.% at WHSV of 1.75 h-1
and 623 K. The predicted optimum yield of gasoline
was 25.5 wt.% at 623 K and WHSV of 1 h-1. |
