To improve the structure order and catalytic activity of mesoporous materials, cubic (SBU-MCM-48) and hexagonal (SBU-MCM-41) mesoporous aluminosilicates containing secondary building units characteristic of zeolite Beta have been prepared, and characterized by means of XRD, N2 adsorption, IR spectroscopy, catalytic cracking reaction compared with the corresponding MCM-41. We found that the introduction of secondary building units characteristic of zeolite Beta into the mesopore wall could be an effective route to improve the acidity of mesoporous materials. Moreover, cubic SBU-MCM-48 has been more active than hexagonal SBU-MCM-41 for cumene cracking reaction.

In our Research, we Used Cornus Wisoniana oil as Feedstock and the High Temperature Pyrolysis Kettle as the Reactor. Examine the Performance of Lanthanum Oxide, Zirconium Sulfate, Calcium Oxide and KF Loaded Catalyst on Cornus Wisoniana oil Catalytic Cracking Reaction. and through the SEM, XRD and FT-IR, Optimal Catalysts were Used to Characterize the Structure. the Results Showed that among KF Modified Catalyst KF Supported on Cao Produced Highest Yield of Bio-Fuel Oil from Cornus Wisoniana oil. when the Dosage of Catalyst Reached 1%, KF Impregnation Ratio of 40%, and Catalyst Calcination for 4h at 600°C, it can be Obtained Highest Yield of Bio-Fuel Oil about 82.7% and Reaction Rate up to 94.1. in Addition to the KF/MgO Having Low Yield about 60.6%, Catalytic Activity of other Four KF Catalysts were Higher than that of Lanthanum Oxide, Zirconium Sulfate and Calcium Oxide. the Catalytic Efficiency of Lanthanum Oxide and Zirconium Sulfate Appeared Similarity and are all Low. the Catalytic Activity of Calcium Oxide is Slightly Higher than the Lanthanum Oxide and Zirconium Sulfate, but Lower than that of KF/CaO Catalyst.

AbstractCe-containing MCM-41 mesoporous materials with large surface area and ordered pore structure system have been possible to be synthesized through a surfactant-assisted approach. The textural properties and structural regularity of the materials varied with the Si/Ce molar ratio. It is found that the band at 970 cm-1 in the FTIR spectrum of the Ce-MCM-41 mesoporous materials might be used as an indicator of the formation of the Ce-O-Si bond and its intensity as a measure of a degree of cerium ion substitution in the framework of Si-MCM-41. When Ni was loaded on the Ce-MCM-41 support, the Ni/Ce-MCM-41 catalysts show high catalytic activity which has strong temperature dependence. The methane conversion over these catalysts reached 60-75 % with a 100 % selectivity towards hydrogen.
