Abstract

The invention discloses a light-oil-type hydrocracking catalyst carrier comprising a modified Y molecular sieve, a modified ZSM-23 molecular sieve and foraminate aluminium oxide. The light-oil-type hydrocracking catalyst carrier comprises the modified Y molecular sieve with high cracking activity, and the modified ZSM-23 molecular sieve with excellent isomerization performance, and therefore the carrier has more comprehensive catalytic performances. A Y molecular sieve is modified to remove aluminium and improve the Si / Al skeleton, thus generating unit cell contraction, reducing the concentration of surface acid sites, and enhancing intensity of the acid sites and producing rich secondary mesopores, thereby facilitating improvement of adsorption and desorption performances of the molecular sieve, reducing diffusion resistance of reactant and resultant and improving the reaction speed, and therefore a catalyst can obtain a high catalytic cracking performance and more light distillates can be produced. The modified ZSM-23 molecular sieve has unobstructed pore channels, a little amount of the acid sites and an outstanding isomerization performance, thereby facilitating isomerization of the light distillates to improve the octane value.

Description

technical field [0001] The present invention relates to a hydrocracking catalyst carrier and its preparation method and application, in particular to a light oil type hydrocracking catalyst carrier suitable for producing light distillate oil, and its preparation method and application. Background technique [0002] With the development of society, people's demand for light fuel oil is increasing day by day, and with the progress of society, the environment's requirements for fuel oil are becoming more and more demanding. The quantity and quality of primary processing of petroleum cannot meet people's needs. Converting heavy distillate oil into high-quality light fuel through secondary processing of petroleum not only fully utilizes limited petroleum resources, but also alleviates the problem of light distillate oil. Market demand. Hydrocracking technology has strong adaptability to raw materials, flexible production plan, and high product quality. It is one of the main mean...
