Embodiment 1

[0029] The USY zeolite (purchased from Zibo, Shandong), 40g of amorphous silica-alumina (purchased from Zibo, Shandong) and 20g pseudo-boehmite (purchased from Zibo, Shandong) that are 15 on a dry basis are added to the mixer until uniform, Then add 3g scallop powder, 5g volume ratio 1:1HNO to the mixture 3 solution and 50g of magnesium acetate and lanthanum nitrate mixed solution (containing Mg 0.5g, La 3g), kneading into a dough suitable for extrusion. It was extruded through a die, and the shape was a slender cylinder (diameter 1.7 mm). It was dried at 120°C for 4 hours and then baked at 550°C for 4 hours. Then it was cut into carrier particles of uniform size (1.7×4.0mm) for use.

[0030] The support was impregnated with 3% NiO and 15% MoO by conventional method 3 After sulfide reduction, it is used to investigate the cracking reaction performance. The reaction raw material is 70% toluene + 20% naphthalene + 10% methylnaphthalene, mixed with 95μg / g tert-butylamine, the re...

[0032] Beta zeolite (purchased from Zibo, Shandong), 40g amorphous silica-alumina (purchased from Zibo, Shandong) and 20g pseudo-boehmite (purchased from Zibo, Shandong) on ​​a dry basis are added to the mixer until uniform, Then add 3g scallop powder, 5g volume ratio 1:1HNO to the mixture 3 Solution and the mixed solution (containing Mg 0.5g, La3g) of 50g magnesium acetate and lanthanum nitrate, knead into the dough suitable for extruding. It was extruded through a die, and the shape was a slender cylinder (diameter 1.7 mm). It was dried at 120°C for 4 hours and then baked at 550°C for 4 hours. Then it was cut into carrier particles of uniform size (1.7×4.0mm) for use.

Embodiment 3

[0035] The dry basis is 20g USY zeolite (purchased from Shandong Zibo) that silicon-aluminum ratio is 15, 20g Beta zeolite (purchased from Shandong Zibo) that silicon-alumina ratio is 15, 40g amorphous silica-alumina (purchased from Shandong Zibo) and 20g Boehmite (purchased from Zibo, Shandong) was added to the mixer until uniform, and then 3g of celadon powder, 5g of HNO in a volume ratio of 1:1 were added to the mixture 3 solution and 50g of magnesium acetate and lanthanum nitrate mixed solution (containing Mg 0.5g, La 3g), kneading into a dough suitable for extrusion. It was extruded through a die, and the shape was a slender cylinder (diameter 1.7 mm). It was dried at 120°C for 4 hours and then baked at 550°C for 4 hours. Then it was cut into carrier particles of uniform size (1.7×4.0mm) for use.

Abstract

The invention relates to a high nitrogen-tolerance hydrocracking catalyst carrier and a preparing method thereof, and mainly aims to solve the problem that a traditional hydrocracking catalyst is poor in nitrogen tolerance. According to the technical scheme, the hydrocracking catalyst carrier is composed of, by weight, 20-40% of at least one of FAU, BEA or MFI type zeolite, 15-36% of amorphous silicon-alumina, 10-20% of pseudo-boehmite, 0.5-3% of metal Mg, and 1-5% of at least one of metal La, Ce, or Ni. In this way, the problem is well solved. The prepared high nitrogen-tolerance hydrocracking catalyst carrier according to the preparing method is applicable to a process of hydrocracking of distillate with nitrogen content lower than 100 microgram / gram, and is high is cracking activity and nitrogen-tolerance property.

Description

technical field [0001] The invention relates to a highly nitrogen-resistant hydrocracking catalyst carrier and a preparation method thereof. Background technique [0002] Hydrocracking technology has the characteristics of strong adaptability of raw materials, great flexibility of product schemes, high selectivity of target products, good product quality, and high added value. It can directly convert various heavy and low-quality raw materials into clean fuel oil and high-quality chemical raw materials. It has become one of the most important heavy oil deep processing techniques in modern oil refining and petrochemical industries, and has been increasingly widely used at home and abroad. Hydrocracking catalysts are generally dual-functional catalysts with low nitrogen resistance and strict requirements on the nitrogen content in the raw material. If they run for a period of time beyond the specified value, the activity of the cracking catalyst will be significantly reduced. ...
