“…In addition, chemical applications require the number of branched chains of olens to be minimized. 12 FTS is able to selectively convert carbon monoxide (CO) to paraffins, olens, alcohols, aldehydes, and ketones with the aid of transition-metal-based catalytic systems (i.e., Ni, 13 Fe, [1][2][3][4] Co, [14][15][16] and Ru 17,18 ). The Fe species behave as active sites to promote the formation of olens while minimizing the formation of methane and the occurrence of secondary hydrogenation.…”

“…However, no detailed explanation is available for the catalysis using AlTS-1 and heteropoly acid. Zeolite ZSM-22 has been used to produce mono-branched trimers of propene due to shape selective catalysis because of the uniform tubular pore (10-memebered ring) of ZSM-22 [29]. Very recently a liquid-phase catalyst, ionic liquids Fig.…”

Oligomerization of isobutene is a very promising reaction not only for the production of isobutene oligomers such as trimers but also for the separation of isobutene from C 4 mixtures. Several solid acid catalysts have been applied for the continuous oligomerization of isobutene in liquid phase. This review analyzes the trimerization of isobutene over various solid acid catalysts such as zeolites, oxides (zirconias and titanias) and acid resins. Trimers selectivity increases with increasing isobutene conversion, irrespective of catalysts such as zeolites and acid resins. Very stable operation with high trimers selectivity is accomplished with WO x /ZrO 2 catalyst having tetragonal zirconia or various zeolite catalysts with high Lewis acid site-to-Brønsted acid site ratio (LA/BA ratio). For a good performance, acid resins should be macroporous and strong acid (sulphonic acid group) with high acid concentration. Inorganic catalysts are superior to acid resins because the deactivated inorganic materials can be regenerated by simple calcination. The WO x /ZrO 2 catalyst may be applied to a commercial process because about several thousand tons of isobutene can be oligomerized per one ton of zirconia catalyst in a catalytic cycle without regeneration. The oligomerization of isobutene may be improved further because the reaction has been started only recently and no research has been done for the optimization of the reaction and catalysts. It is expected to develop a new inorganic catalyst having suitable acidity, LA/BA ratio and phase, etc. by further research. The isobutene trimers, with or without hydrogenation, may be used for various purposes, and the importance of this trimerization reaction will be increased considering the expected surplus of isobutene due to the banned use of methyl-tert-butyl ether.

“…0.47 × 0.55 nm, [1,2] has been widely applied in catalytic conversions such as isomerization, [3][4][5][6][7] paraffin hydroconversion, [8] and propene trimerization. [9] Notably, the high-silica zeolite with a TON structure such as ZSM-22 is synthesized in the presence of organic templates. [10] The use of organic templates not only increases the synthesis cost but also produces polluted wastes, which strongly limit its practical applications in the industrial processes.…”
