Adsorption Desorption

Five kinds of modified Y zeolite-based fluid catalytic cracking (FCC) catalysts were prepared. The N2 adsorption desorption and NH3 temperature-programmed-desorption (NH3-TPD) were used to investigate the pore structure and acidic properties of the catalysts. The effects of pore structure and acidic properties of catalysts on the catalytic cracking performance of Venezuelan heavy oil were carried out using an advanced cracking evaluation unit. The results of N2 adsorption desorption and NH3-TPD show that CAT-A and CAT-B catalysts with rundle pore distribution have a similar pore sizes and acidSubscript textSubscript textic properties. The catalytic cracking results show that the acidic properties and the pore distribution of the catalysts have obvious effects on the conversion and product distribution. The light oil yield and total liquid oil yield can reach 58.75wt% and 73.83 wt%, respectively, under reaction temperature of 520°C.

The flash pyrolysis of Huolinhe coal was carried out in a fast-entrained bed reactor. The investigation focuses on the effects of pyrolysis temperature and particle size on pyrolysis product distributions and gas and liquid compositions. Increasing temperature results in an increase of the gaseous product. There is an optimum temperature on the maximum liquid yield, which is around 650°C. An increase in particle size leads to a decrease of liquid products. Some amount of phenol group was found in the liquid products, which may produce the chemicals with high value. The results provide fundamental data and optimal conditions to maximize light oils yields for the coal topping process.
