On the catalytic performance in isopropylation of benzene over H/β zeolite catalysts: Influence of binder

A largely unsolved problem in environmentally detrimental waste products is utilization of flyash. Zeolite beta is synthesized using flyash as a source of silica and alumina. Isopropylation of benzene has been used as a probe reaction to evaluate the quality of flyash-based zeolite beta. Influence of the different percentages of alumina binder and formulations on the catalytic performance in isopropylation of benzene reaction over protonic forms of flyash zeolite beta (H/β) has been investigated. It is also shown that, flyash based zeolite beta synthesis opens new possibilities for commercialization of environmentally detrimental product to cost-effective and eco-friendly catalyst of commercial interest.
