Embodiment 1

[0025] Use lanthanum-modified alumina as the carrier, wherein the content of lanthanum in the carrier is 2% by mass, the alumina carrier is calcined at 1000°C, the density of the carrier is measured to be 0.68g / ml, and the specific surface area is 155m 2 / g, the volume average pore diameter is 18nm.

[0026] Dissolve an appropriate amount of nickel nitrate, lanthanum nitrate and silver nitrate in water to make an aqueous solution according to the catalyst to be prepared, impregnate the carrier with the same amount of impregnation, and impregnate twice, and dry at 120°C after each impregnation, and dry at 450°C Calcined at lower temperature, thus Catalyst 1 was prepared. Catalyst 1 contained: 12% nickel, 2% lanthanum (not including that carried by the support) and 1% silver, the balance being support.

Embodiment 2

[0028] Use lanthanum-modified alumina as the carrier, wherein the content of lanthanum in the carrier is 2% by mass, the alumina carrier is calcined at 1100°C, the density of the carrier is measured to be 0.7g / ml, and the specific surface area is 110m 2 / g, the volume average pore diameter is 15nm.

[0029] Dissolve an appropriate amount of nickel nitrate, lanthanum nitrate and silver nitrate in water to make an aqueous solution according to the catalyst to be prepared, impregnate the carrier with the same amount of impregnation, and impregnate twice, and dry at 120°C after each impregnation, and dry at 450°C Calcined under lower pressure, thus preparing Catalyst 2. Catalyst 2 contained: 18% nickel, 1% lanthanum (not including that carried by the support) and 2% silver, with the balance being support.

Embodiment 3

[0031] Use lanthanum-modified alumina as the carrier, wherein the content of lanthanum in the carrier is 2% by mass, the alumina carrier is calcined at 1100°C, the density of the carrier is measured to be 0.7g / ml, and the specific surface area is 110m 2 / g, the volume average pore diameter is 15nm.

[0032] Dissolve an appropriate amount of nickel nitrate, lanthanum nitrate and silver nitrate in water to make an aqueous solution according to the catalyst to be prepared, impregnate the carrier with the same amount of impregnation, and impregnate twice, and dry at 120°C after each impregnation, and dry at 450°C The catalyst 3 was prepared by calcining at the bottom. Catalyst 3 contained: 25% nickel, 2% lanthanum (not including that carried by the support) and 0.5% silver, with the balance being support.

Abstract

The invention relates to a selective hydrogenation catalyst for C5 cracking and belongs to the technology field of hydrogenation catalysts. In order to meet the urgent need of the selective hydrogenation catalysts for the C5 cracking, the invention provides a catalyst for selective hydrogenation in the C5 cracking, which contains the following components in the given mass percentages: Ni 10-35%, La 0.5-3%, Ag 0.3-3% and aluminum oxide carrier 59-89.2%, calculated on basis of the total mass of the catalyst. The catalyst can also contain K and / or Sr or Pb. The catalyst is used for selective hydrogenation in the C5 cracking as well as hydrogenation in the C5 cracking and excellent in conversion rate, selectivity and stability.

Description

technical field [0001] The invention relates to a hydrogenation catalyst, more specifically, the invention relates to a catalyst for selective hydrogenation of cracked carbon five. Background technique [0002] With the continuous expansion of the scale of the ethylene plant, the by-product C5 fractions are also increasing. The C5 yield varies with the cracking depth and cracking raw materials of the ethylene plant, and is generally 10-15% of the ethylene output. With the progress and completion of the second round of transformation of the ethylene plant, the by-product cracked C5 fraction in my country is about 1.5 million tons per year. However, compared with the high utilization rate of C5 fractions in foreign countries, the utilization of C5 fractions in my country is far from enough. Most of them are used as fuel, and the added value of C5 fractions is basically not utilized. At present, Sinopec only has Shanghai The petrochemical construction has a set of 25,000 tons / y...
