preparation example Construction

[0023] The preparation method of the butene composite catalyst provided by the present invention comprises mixing HZSM-5 zeolite and alumina powder, adding a small amount of water, and also adding a peptizer, such as dilute nitric acid, fully kneading until uniform, then extrusion molding, and drying , The carrier is obtained after roasting. The carrier is treated with water vapor at 450-650° C. for 2-10 hours, and the amount of water vapor used is 10-30 times the mass of the carrier. Then impregnate with a solution of water-soluble nickel salt, the impregnating temperature is 60-90°C, and the impregnating liquid / solid ratio is 1-3:1. After impregnation, the solid is dried and calcined at 400-550° C. in an inert gas, preferably nitrogen.

[0024] The preparation method of the gasoline composite catalyst comprises fully mixing amorphous aluminum silicate, alumina powder and a small amount of kale powder, and the amount of kale powder is 0.5 to 2.0% of the total mass of amorpho...

example 1

[0033] The following examples prepare butene complex catalysts.

[0034] (1) Preparation of carrier

[0035] Take 15 grams of SiO 2 / Al 2 o 3 Mix HZSM-5 zeolite with a molar ratio of 90 and 5 grams of alumina powder, add 12 grams of deionized water and knead, then extrude, dry at 120°C for 4 hours, and bake at 540°C for 4 hours to obtain a carrier. The carrier was treated with water vapor at 450° C. for 8 hours, and the amount of water vapor used was 20 times the mass of the carrier. Then crushed into 0.6 ~ 0.9 mm particles.

[0036] (2) Preparation of catalyst

[0037] Get 20 grams of carrier granules that (1) step makes, add by 16.0 grams of nickel nitrate [Ni(NO 3 ) 2 ·6H 2 [0] and 40 milliliters of deionized water in the impregnating solution, soaked at 60° C. for 3 hours, dried at 120° C. for 4 hours, and roasted at 550° C. in nitrogen for 8 hours to obtain catalyst A, whose composition is shown in Table 1.

example 2

[0039] Prepare the carrier by the method of example 1 (1) step, the difference is that 10 grams of SiO 2 / Al 2 o 3 HZSM-5 zeolite with a molar ratio of 180 was mixed with 10 g of alumina powder, then extruded, dried and calcined to obtain a carrier, and then the carrier was treated with water vapor at 520°C for 6 hours, and then crushed into granules.

[0040] Prepare catalyst by the method of example 1 (2) step, difference is that the nickel nitrate used for preparing impregnating liquid is 8 grams, impregnate carrier with impregnating liquid at 80 ℃ for 4 hours, after drying, roasting, catalyst B is obtained, and its composition is shown in table 1.

Abstract

A method for overlay production of the fuel-oil by components of C4 with butylene consists of making the said components of C4 carry out the congruent reaction of butylenes first, afterwards, separating the distillates of gasoline and fuel-oil of the liquid products of the congruent reaction, and then making the olefin of the said gasoline distillate carry out the congruent reaction of gasoline. The components of C4 of this method is of double congruences, which not only can reduce the reaction pressure in each step, but also can increase the yield rate of fuel-oil of the congruent product.

Description

technical field [0001] The present invention is a kind of C containing butene 4 The method for producing diesel by superposition of components, specifically, is a method for producing diesel by superposition of butene. Background technique [0002] With the continuous improvement of my country's crude oil processing capacity and ethylene production, catalytic cracking units and steam cracking units have produced a large amount of liquefied petroleum gas by-products. In recent years, with the increasing popularity of civil natural gas, the market demand for liquefied petroleum gas to be directly used as fuel is increasing. smaller. Therefore, a large amount of liquefied gas urgently needs to find a new way of chemical utilization. [0003] The liquefied gas contains a considerable amount of butene, which can be used to produce composite gasoline and composite diesel through superposition reaction. Due to the high content of olefins in composite gasoline, it cannot meet the ...
