Cobalt and/or manganese incorporated berlinites (CoMnAPO4) and aluminophosphate molecule sieve (CoMnAPO-5) were hydrothermally synthesized, characterized by XRD, FT-IR, XPS and SEM, and employed as catalysts in the oxidation of cyclohexane with molecular oxygen at 348 K under atmospheric pressure. It was found that the berlinite-based catalysts were more selective for the production of KA oil, stable during the reaction, but slightly less active for the conversion of cyclohexane, when compared to their molecular sieve counterparts. The CoMnAPO4exhibited a better catalytic performance, due to a synergic effect, than the CoAPO4or MnAPO4.

Zeolite Crystals

MER-type zeolite is an interesting microporous material that has been widely used in catalysis and separation. By carefully controlling the synthesis parameters, a procedure to synthesize K-MER zeolite crystals with various morphologies has been developed. The silica, water and mineralizer content in the synthesis gel, as well as crystallization time and temperature, have a profound impact on the crystallization kinetics, resulting in zeolite solids with various degrees of crystallinity, crystal sizes and shapes. K-MER zeolite crystals with nanorod, bullet-like, prismatic and wheatsheaf-like morphologies have been successfully obtained. The catalytic performances of the K-MER zeolites in cyanoethylation of methanol, under novel non-microwave instant heating, have been investigated. The zeolite in nanosize form shows the best catalytic performance (94.1% conversion, 100% selectivity) while the bullet-like zeolite gives poorest catalytic performance (44.2% conversion, 100% selectivity).
