Problems solved by technology

Its shortcoming is that because it takes the production of aromatics as the main purpose, the raw material oil obtains 45-65% (accounting for raw material oil weight) liquid after the first stage reaction, and the liquid yield is not high
The disadvantage is that the yield of liquid is not high, and the yield of liquefied gas is too high. In addition, if the raw material contains impurities such as sulfur, the loaded metal component mixed with rare earth oxide or antimony oxide does not have good sulfur conversion ability, and it may It will cause difficulty in the application of the catalyst. When the sulfur content in the raw material is high, the sulfur content of the product will also be high when used as a gasoline blending component

Embodiment 1

[0034] Preparation of the catalyst of the present invention.

[0035] (1) Preparation of molecular sieve carrier: take 130 g of nanometer HZSM-5 molecular sieves with a silicon-aluminum ratio of 38, 70 g of pseudo-boehmite powder, mix well, add 1.8 milliliters of 1: 1 solution of nitric acid and 50 milliliters of deionized water, and knead Finally, it is extruded into a strip with a diameter of 1.6 mm and a length of 3 to 5 mm in an extruder, dried at 110°C for 12 hours, and calcined at 550°C for 3 hours.

[0036] (2) Active metal loading: Take 100 g of the above-mentioned carrier, impregnate at 25° C. for 3 hours with 100 ml of an aqueous solution containing 20.5 grams of molybdenum trioxide and 7.41 grams of zinc nitrate, dry at 110° C. for 12 hours, and roast at 550° C. for 4 hours.

[0037] (3) Hydrothermal treatment: put the catalyst prepared in step (2) into a tubular reactor, heat up to 520°C in an air stream under normal pressure, then change to steam at this temperatu...

Embodiment 2

[0040] Prepare other several catalysts B-E by the method for embodiment 1, difference is to change the second metal type and content, be respectively B (aluminum 12.0%, nickel 2.5%), C (molybdenum 12.0%, tungsten 2.5%), D ( Molybdenum 12.0%, Cobalt 2.5%), E (Molybdenum 12.0%, Iron 3.0%).

Embodiment 3

[0042] Catalyst F is prepared by the method of embodiment 1, and difference is that the carrier that step (1) step is made is advanced steam treatment, then introduces active metal (molybdenum 12.0%, nickel 2.5%) with the method for (2) step .

Abstract

The invention relates to a preparation method for a modification catalyst of condensate oil containing sulphur and an application thereof which are characterized in that the catalyst formation is realized by loading molybdenum, Zn, Co, Ni, and the like, on a molecular sieve; the preparation method comprises two procedures, wherein, one procedure is that an active component is kneaded and added when a carrier is prepared; hydrothermal treatment is carried out after forming and roasting and the catalyst is obtained; the other procedure is that the carrier is first prepared; an active metal is brought into the carrier by the corporate immersion method; then hydrothermal treatment is carried out and the catalyst is obtained. The application is that the modification catalyst is used for modifying the condensate oil containing sulphur and a catalytic process is carried out under the condition with the presence of hydrogen or with the absence of hydrogen.

Description

technical field [0001] The invention relates to the technical field of petroleum processing catalysts, and relates to a preparation method and application of a sulfur-containing condensate oil upgrading catalyst, more specifically, a preparation of a catalyst for sulfur-containing low-octane condensate oil upgrading Method, and use of said catalyst for upgrading condensate oil. Background technique [0002] The rational and full use of limited oil and natural gas resources has been valued by countries all over the world. With the intensified development of petroleum and the large-scale exploitation of condensate oil and gas fields, a large amount of condensate oil products (C 3 -C 12 ), condensate is unfractionated liquid hydrocarbon recovered together with natural gas and oil field gas, it is a mixture of short-chain hydrocarbons and long-chain hydrocarbons, the yield of naphtha is usually 60-80m%, and the yield of diesel oil is usually In 20 ~ 40m%. However, a large am...
