Dimerization of Hexadecene with Acid Mesoporous Silica‐Alumina Catalysts

Abstract

Catalytic dimerization of 1-hexadecene is shown to be a promising path to make high quality base oil. The base oil is produced by hexadecene dimerization with acid mesoporous silica-alumina catalyst, followed by distillation and hydrogenation. The base oil stock had a high viscosity index (typically 140-150) and a low volatility (Noack typically less than 8 %). The best performance in hexadecene dimerization was achieved with the MCM-22 zeolite embedded MCM-41 catalyst within the silica-alumina catalysts compared. Commercial mesoporous silica-alumina catalysts behaved similarly to a non-commercial MCM-41 catalyst. Y-zeolite and ion exchange resin Amberlyst-35 deactivated fast.

Advances in morphology-controlled alumina and its supported Pd catalysts: synthesis and applications

“…Benefiting from the high mechanical strength and relatively low price, alumina materials are widely used in medical, mechanical, electronic, chemical, and other fields. 6,7 Among numerous catalytic materials, alumina is pivotal in the current chemical industry. Its unique characteristics listed above have made it a popular choice as the catalyst, more commonly as the support of catalyst.…”
