Catalytic cracking of C4 alkene to propylene catalyst
Catalyst of using C4 alkene catalytic craking to prepare propylene
As the demand of propylene was highly increase,our study focus on he propylene production in the field of petroleum-based route.In order to make the best of C4 olefins,which are subsidiary products of progress to produce ethylene.
The hydrocarbon catalytic cracking process with shape selective zeolite as catalyst,at temperature 450℃ can obtain high propylene selectivity.The result as follows:
