Abstract
The production of liquid fuels using a catalytic
cracker generates a significant amount of lighter fractions of olefinic nature.
The use of oligomerization reactions to convert lighter olefin cuts into middle
distillates to incorporate in the diesel pool is a promising process for the production
of clean diesel fractions.
Researchers studied 1-butene oligomerization
over H-ZSM-5 zeolite in a differential reactor operating at ambient pressure.
They examined the effect of reaction conditions, such as reaction temperature,
contact time and partial pressure, on the activity, selectivity and stability
of the catalyst. Their results reveal that an increase in the reaction
temperature and/or partial pressure and in the contact time produces an
improved catalyst activity.
