posted on 2017-02-03, 00:00 authored by Naixin Wang, Xieqing Wang, Zelong Liu, Yuxia ZhuX oil,
a byproduct from caprolactam manufacture, is a complex mixture
of organic oxygenates. In order to transform X oil into hydrocarbon
fuel, the catalytic cracking reaction pathway and product composition
of model oxygenates in X oil were investigated. The model compounds
included cyclohexanol, cyclohexanone, bicyclic ketones, oxydicyclohexane,
and cyclohexyl butyrate. The product distribution of mixed feedstock
could be predicted, as the product compositions would not be influenced
when the model compounds had a catalytic cracking reaction together.
Oxygen balance during the catalytic conversion process was also studied.
The main deoxygenation way of these five model compounds was dehydration,
and the next was decarbonylation. The intent was to obtain a reaction
pathway which could be used for modeling the catalytic cracking of
X oil.
