Homogeneous catalysts such as hydrofluoric acid (HF) and sulfuric acid (H2SO4) have been successfully used to catalyze these processes (Rao and Vatcha, 1996). However, due to the inherent toxicity and the environmental hazard associated with these acid catalysts much research has been done over...
To avoid some of the problems associated with earlier commercial alkylation processes, solid zeolite-containing catalysts have been used in recent years to promote the alkylation of aromatic compounds with olefins and other alkylating agents, especially the alkylation of benzene with ethylene. Such zeolit...
A method is provided for preparing a para-selective, zeolite-based aromatics alkylation catalyst by treating a ZSM-5 type zeolite base catalyst composite with an aqueous magnesium nitrate solution and thereafter calcining the composite so treated. Such catalysts can be used in alkylation processes to...
Emerging Trends in Solid Acid Catalyst Alkylation Processes The development of green catalytic processes is receiving more focus during recent times due to ever-increasing environmental concerns. As a result of this, numerous attempts are being made to develop eco-friendly catalyst systems. This ......
