Embodiment 1

[0040] Using the equal volume impregnation method, dissolve 50.21g ethyl orthosilicate in an appropriate amount of absolute ethanol, add 132.80g Al 2 o 3 , impregnated at room temperature for 4h, dried at 120°C for 8h after impregnated, and calcined at 800°C for 4h after hydrolysis to obtain the desired silica-alumina carrier. Add 68.7g of magnesium nitrate hexahydrate to the prepared silica-alumina carrier, add peptizer accounting for 2.3% of the total mass of the solid, a binder accounting for 1.8% of the total mass of the solid, and an extrusion aid accounting for 3.9% of the total mass of the solid, kneading After the plastic is formed, it is extruded with a cylindrical hole-extruding abrasive tool, with a diameter of 3.5 mm and a length of 5.0 mm. Dry in an oven at 120°C for 8 hours, and bake at 800°C for 4 hours to obtain the final shaped carrier.

Abstract

The invention discloses a catalyst for producing clean fuel oil by using coal tar and a preparation method of the catalyst. The catalyst comprises a carrier and active components and is characterized in that the carrier comprises alumina, monox and magnesia; the active components are composed of WO3 and NiO or of MoO3 and NiO; the catalyst further comprises an auxiliary agent composed of K2O and Ga2O3; and the quality of the carrier accounts for 62-88% of the total quality of the catalyst, the quality of the active components accounts for 11-32% of the total quality of the catalyst, and the quality of the auxiliary agent accounts for 1-6% of the total quality of the catalyst. The catalyst has high hydrogen desulfurization, hydrodenitrification, hydrodeoxygenation, aromatics saturation and ring-opening reaction activity and proper acid sites, inhibits coking of easy-to-coke substances in coal tar as coked substances can block a reactor, improves stability of catalyst, and allow petroleum naphtha and diesel oil with low sulfur and nitrogen content to be obtained by hydrotreating coal tar.

Description

technical field [0001] The invention relates to a catalyst for producing clean fuel oil from coal tar and a preparation method thereof. Background technique [0002] With the rapid development of the world economy, the demand for fuel oil products is increasing, and the quality requirements for oil products are becoming more and more stringent, while the oil resources as traditional liquid fuels are decreasing day by day, so it is urgent to develop new Substitute oil products to alleviate the oil tension that mankind will face. At present, my country's energy status is "short of oil, less gas, and rich in coal". In the case of limited oil resources, it is of great practical and strategic significance to develop technologies for producing clean oil products from coal. [0003] Coal tar is a by-product of the production of semi-coke, coke, and coal gasification, with an annual output of about 1,500 tons, most of which have not been rationally utilized. A part of coal tar und...
