Supercritical catalytic cracking of n-decane over HZSM-5 molecular sieve catalyst was investigated.

The catalytic cracking performance of phosphorus modified HZSM-5 zeolite catalyst by hydrothermal treatment was studied with FCC light gasoline as the feedstock in a fixed bed reactor.

Synthesis of 2-acetylthiophene by HZSM-5 zeolite catalyst;

Piperazine and triethylenediamine were prepared with ethylenediamine as raw material and HZSM-5 zeolite modified with CaCl_2 was selected as best catalyst.

The main components of biodiesel including methyl oleate,methyl palmitate,methyl stearate,methyl linoleate and methyl laurate were modified at 250℃~350℃ using HZSM-5 zeolite catalyst to decrease the cold filter plug points(CFPP) of biodiesel.

Influence of the acidities of the HZSM-5 zeolites modified by MoO_3;

The bifunctional catalysts for one-step DME synthesis were prepared by mixing JC207 catalyst and HZSM-5 zeolites modified by MgO、CaO、ZnO,respectively.

A co-catalyst for maximizing propylene production in FCC unit has been developed by modifying HZSM-5 molecular sieve with P,Al and Fe and tested and evaluated on fixed-bed micro-reactor.

Effects of feeding order of different feedstocks on direct amination of isobutene to tert-butylamine over HZSM-5 molecular sieve catalyst in fixed-bed microreactor were studied.

HZSM-5 molecular sieve catalyst modified with SiO_2 was prepared by impregnation of HZSM-5 molecular sieve in liquid silicon oil.

The Effect of Static Hydrothermal Dealumination on the Structure, Acidity and Catalytic Properties of HZSM-5;

Firstly,experiment gantry was designed and built; Then HZSM-5(Si/Al=38%)was selected as the main solid acidic catalyst of DME dehydration catalyst, while the Ga2O3 as auxiliary agent; And CNZ-1was taken as the catalyst for Methanol r.
