example 1

[0031] This example is the catalyst used in the preparation of the present invention.

[0032]Take 1000g of HZSM-5 molecular sieve (produced by Beijing Huier Company) with a silicon-aluminum ratio of 38, 300g of pseudo-boehmite (produced by Shandong Aluminum Factory), and 30g of celadon powder, and mix them evenly. Then add nitric acid solution (60g 40% nitric acid + 980g deionized water), fully knead, then extrude into strips and form pellets in a spheronizer, dry the pellets at 120°C for 6h, and roast them in a muffle furnace at 600°C for 3h to obtain 3.5mm pellet carrier.

[0033] Get 100g pellet carrier, impregnate with 100g nickel / La nitric acid solution (16g nickel nitrate Ni(NO 3 ) 2 .6H 2 O+12gLa(NO 3 ) 3 .6H 2 (0+100g deionized water), impregnated at 50°C for 8h, dried at 120°C for 6h, and calcined at 500°C for 3h in a muffle furnace to obtain catalyst A.

example 2

[0035] This example illustrates the process effect of dry gas and C4 component catalytic reaction.

Abstract

Disclosed is a method for utilizing petroleum cracking dry gas and C4 components to produce clean fuel oil, which is characterized in that: the method comprises: supplying the dry gas and C4 components to a reactor filled with catalyst, carrying out the catalytic reaction under conditions of reaction temperature of 250 to 500DEG C, reaction pressure of 0.1 to 1.0MPa and weight space velocity of 0.2 to 10h<-1>, then separating the gasoline fraction and diesel oil fraction in reaction products to obtain the clean engine fuel oil.

Description

technical field [0001] The invention relates to the effective utilization of petroleum cracking dry gas and C4 components, which can increase the economic value of dry gas and C4 components. Specifically, it is a method for converting ethylene in dry gas and butene in C4 components into clean fuel oil (gasoline and diesel). Background technique [0002] With the increasing shortage of global oil resources and high oil prices, how to make good use of limited resources has become one of the problems that oil refining companies need to solve. Catalytic cracking is the main operating unit of a refinery. The worldwide catalytic cracking process accounts for about 35% of the primary processing volume of crude oil. At present, my country's catalytic cracking processing capacity has exceeded 100 million tons. Catalytic cracking products include dry gas, liquefied petroleum gas, gasoline, diesel oil, oil slurry, coke, etc. Among these products, dry gas has a low value and is an unde...
