Trimerization of isobutene over Amberlyst-15 catalyst

Oligomerization of C2-C4 Hydrocarbons in the Presence of Ruthenium-Nickel Supported Catalysts

“…This leads to increasing the selectivity of isooctane yield. The temperature dependence of the division of oligomer had been studied by Alcantara et al [27] since oligomer splitting moves toward more important side at temperature above 100-110 0 C. During the C2-C4 oligomerization reaction to form di-, tri-or high molecular weight hydrocarbons depends on the metal content and their dispersion on surface of the carrier. Comparing to the both mono and bimetallic oligomerization catalysts, the Ru-based catalysts less active than Ru-Ni system.…”

Application Possibilities of Zeolite Catalysts in Oligomerization of Light Olefins

“…Another advantage is that the oligomerization is flexible in terms of the average molecular weight of the hydrocarbon product and thus in terms of the composition (gasoline, JET, and gas oil fractions). The oligomerization has already been studied by using a variety of catalysts [3], such as solid phosphoric acid [4][5][6], zeolites [7][8][9][10][11][12][13][14][15], acidic ion exchange resins [14][15][16][17][18][19][20], metal oxide catalysts [21][22] and ionic liquids [23][24][25][26].…”

Trimerization of Isobutene over Solid Acid Catalysts: Comparison between Cation-exchange Resin and Zeolite Catalysts

“…2 Triisobutenes, for example, are considered to be highly useful for the synthesis of specialty chemicals. 2 Triisobutenes, after hydrogenation, can be used as premium solvents and additives for kerosene and jet fuel.…”

“…2 Triisobutenes, for example, are considered to be highly useful for the synthesis of specialty chemicals. 2 Triisobutenes, after hydrogenation, can be used as premium solvents and additives for kerosene and jet fuel. 3 A surplus of isobutene is expected because the blending of MTBE (methyl-tert-butyl ether) in gasoline has been banned in California 4 since 2004 due to contamination caused by the dissolution of MTBE in underground water.…”
