Organosilane surfactant-directed synthesis of hierarchical mordenite with enhanced catalytic performance in the alkylation of benzene with 1-dodecene

To improve the stability of mordenite (MOR) in the alkylation of benzene with long chain olefin, hierarchical MOR zeolites were synthesized by using organosilane surfactant [3-(trimethoxysilyl)propyl]octadecyldimethyl-ammonium chloride (TPOAC) as the mesopore structure-directing agent. Our findings reveal that the crystal size, hierarchical structure, and acidic properties of the mesoporous MOR zeolites are significantly influenced by the TPOAC/SiO2 molar ratio in the synthesis gel. Moreover, the hierarchical MOR zeolite synthesized under the optimized synthesis conditions presented the pure phase of the MOR framework and uniform mesoporous distribution. More importantly, the catalytic performance evaluated by the alkylation of benzene with 1-dodecene indicates that the optimal mesoporous MOR zeolite shows improved stability and comparable selectivity of 2-phenyl alkane (2-LAB) around 80% compared to the conventional sole microporous MOR zeolite. The improved stability of the mesoporous MOR zeolite can be attributed to the enhanced diffusivity of long chain linear alkylbenzenes and oligomers due to interconnected meso-/microporosity in the MOR.

Selective synthesis of linear alkylbenzene by alkylation of benzene with 1-dodecene over desilicated zeolites

The alkylation of benzene with 1-dodecene to linear alkylbenzenes (LAB) was investigated over 12-ring zeolites MOR, BEA, and FAU with varying framework topologies and Si/Al ratios. The reaction was carried out under a high-pressure, 20 bar, in a fixed-bed flow reactor at 140 C, using WHSV 4 h-1, benzene/1-dodecene molar ratio of 6.0 and time-on-stream of 6.0 h. In contrast to MOR and BEA zeolites, FAU exhibited the lowest selectivity (24%) to the desired 2-phenyl dodecane (2-LAB) due to its large cavities. The MOR and BEA with different Si/Al ratios were further desilicated using alkali-metal treatments (0.2 M and 0.05 M NaOH) to create hierarchical porous structure. The desilication of both zeolites improved the conversion of 1-dodecene and the selectivity to 2-LAB. The excellent stability resulting from desilication is attributed to a better diffusivity of the LAB isomers, shortening of real contact time, due to the enhanced mesporous structure in both zeolites and the higher Lewis acidity. The selectivity to 2-LAB increased to 70% over desilicated MOR (Si/Al ratio = 20) compared with a selectivity of 35% over desilicated BEA (Si/Al ratio = 24).

One-pot synthesis of a novel magnetic carbon based solid acid for alkylation

Magnetic carbon based solid acid has been synthesized via the one-pot hydrothermal carbonization of chitosan, magnetic core and hydroxyethylsulfonic acid at 160°C for 4 h. Chitosan was used as the carbon resource to protect the magnetic core from hydroxyethylsulfonic acid. The magnetic carbon based solid acid owned high BET surface and core shell structure, which provided the easily accessible acid sites on the carbon shell. The novel carbon based solid acid exhibited high activities for the hydrophobic alkylation of 1- dodecene and benzene, which was difficult to activate by traditional carbon based solid acids. The simple magnetic recovery added the advantages of the solid acid. The high activities for hydrophobic reactions, high stability and magnetic recovery were the key properties of the solid acid, which greatly enlarged the application area of the solid acid.
