Deskripsi
Boron was implemented to promote the catalytic behavior of H-ZSM-5 zeolite in methanol to propylene (MTP) process. A series of crystalline borosilicates with different boron contents were synthesized using a seed-assisted hydrothermal technique and characterized well. Results revealed that increasing the boron coefficient improved lifetime and propylene productivity of zeolite by 20 and 24%, respectively. Hierarchal micro-mesoporosity and the distribution of acid sites made a substantial contribution to H-[B]-ZSM-5 performance in MTP. Boron played a significant role in tuning the acidity of the catalyst and improved its stability by controlling the formation of heavy hydrocarbons (C5+) in the MTP reaction.
