    摘要: A catalytic cracking catalyst having a rich mesoporous structure and a preparation method therefor. The catalyst, on a dry basis, comprises: 10-35% by weight of a meso and macro pore aluminum oxide based on aluminum oxide, 5-30% by weight of an acidifying binder based on oxide, 2-20% by weight of a second binder based on oxide, 20-60% by weight of a zeolite, and 5-50% by weight of a clay; the meso and macro pore aluminum oxide is an aluminum oxide with a pseudo boehmite structure, which has a total pore volume of 0.5-2.0 mL/g, an average pore size of 5-30 nm, and a specific surface area of 250-450 m 2/g, wherein the pore volume of 5-100 nm pores accounts for 80% or more of the total pore volume; the weight ratio of the acidifying binder to the meso and macro pore aluminum oxide is 0.5-1.0. The catalytic cracking catalyst according to the present invention has a rich mesopore structure, a total pore volume not less than 0.200 mL/g, the pore volume of 2-100 nm meso and macro pores accounting for 70% or more of the total pore volume, and the pore volume of 4-50 nm mesoporous pores accounting for 60% or more of the total pore volume, as measured by a low-temperature nitrogen adsorption method. Therefore, it has a great attrition resistance strength, an enhanced heavy oil conversion capacity, a significantly improved coke selectivity.

    摘要: According to the present invention, a molded catalyst for use in the production of methyl methacrylate can be provided. The molded catalyst comprises synthetic faujasite-type zeolite and a layered magnesium silicate compound, wherein the sulfur content in the layered magnesium silicate compound is 0.10% by weight or less. According to the present invention, a method for producing methyl methacrylate can also be provided. The method is characterized by comprising a step of carrying out a gas-phase catalytic reaction of methyl ±-hydroxyisobutyrate using the above-mentioned molded catalyst for use in the production of methyl methacrylate.
