文摘
- •
Different structural types of zeolites (mostly 10-ring) were tested as additives increased VGO conversion.
- •
Increased rate of hydrogen transfer reactions decreased the yield of propylene.
- •
Maximum propylene yield of 10.9 wt.%, was achieved over ferrierite.
- •
Higher rate of cracking of iso-paraffins and olefins decreased gasoline yield.
- •
Kinetic parameters obtained over zeolite SSZ-74 showed lower activation energy.
