Comparative study of the catalytic performance of physically mixed and sequentially utilized γ-alumina and zeolite in methanol-to-propylene reactions.

This study aimed to investigate the catalytic performance of H-ZSM-5 zeolite compared with physically mixed and sequentially used synthesized γ-alumina and zeolite in the methanol-to-propylene (MTP) reaction. A facile, green and cost-effective method was first applied to prepare a mesoporous γ-AlO support using a combination of sol-gel and hydrothermal methods via a few consecutive steps. This process was carried out using aluminium nitrate and polyethylene glycol with different molecular weights as non-ionic surfactants.

Synthesis, characterization, and methanol steam reforming performance of Cu/perovskite-structured catalysts.

In the present work, Cu/perovskite-type structures of the general formula Cu/Ca(ZrTi)O (x = 1, 0.8, 0.6) were synthesized via sol-gel process and afterwards using wetness impregnation method to prepare copper-based catalysts.
