Catalytic performance of imidazole modified HZSM-5 for methanol to aromatics reaction

Near-Graphite Coke Deposit on Nano-HZSM-5 Aggregates for Methanol to Propylene and Butylene Reaction

Nanocrystal HZSM-5 zeolite aggregates with different SiO2/Al2O3 molar ratios were prepared under low temperature and were used to catalyze the conversion of methanol to propylene and butene. The coke location, coke content, and coke species deposited on HZSM-5 aggregates were investigated. The near-graphite carbon on the external surface of HZSM-5 zeolite (SiO2/Al2O3 molar ratio = 400) was dist...

Catalytic Conversion of Methanol to Hydrocarbons over different wt% Ni-HZSM-5

Due to crude oil is limited, new resources for fuel and petrochemicals are important to be developed. Biogas or NG (Natural Gas) can be easily converted into methanol which can be reacted over zeolite to produce olefins and gasoline. HZSM-5 zeolite catalyst has been used in this study and its modification by (0.5wt%, 1wt%, 2wt% and 4wt %) Ni to convert methanol to hydrocarbons (MTH). Catalysts ...

Catalytic Cracking of Butene to Propylene over Modified HZSM-5 Zeolites

Catalytic cracking of butene to propylene was carried out in a continuous-flow fixed-bed reactor over HZSM-5 catalysts modified by nickel and phosphorus. The structure and acidity of catalysts were measured by N2 adsorption, NH3-TPD and XPS. The results revealed that surface area and strong acid sites both decreased with increasing phosphorus loadings. The increment of phosphorus loadings reduc...

The Synthesis of SAPO-34 at Different Crystallization Temperature and its Catalytic Performance for Methanol to Olefins Reaction

Catalytic Conversion of Acetone to Monoaromatic Chemicals using HZSM-5

The effects of process variables (temperature, space velocity, water addition and Si/Al ratio) on the conversion of acetone to aromatic chemicals have been investigated. The reaction is carried out by fixed bed reactor at an atmospheric pressure to examine the activity and selectivity of HZSM-5. The results show that HZSM-5 exhibited a high active and a shape-selective catalyst for the formatio...
