Abstract

The invention discloses a production method of a catalyst for a slurry reactor residual oil hydro-conversion technology. The production method of the catalyst comprises the following steps: reacting araw material with a sorbitan compound and a sulfide at 100-350 DEG C, and stirring by using a mechanical stirring device in a reaction kettle until the reaction is completed; and after the reaction is completed, drying an obtained reactant in the air at 60-80 DEG C for 2-24 hours, and cooling to room temperature to obtain the catalyst for slurry reactor residual oil hydro-conversion technology; introducing the dried catalyst for slurry reactor residual oil hydro-conversion technology in a smashing device to be smashed, wherein the smashing device is provided with a filtering assembly, and thecatalyst is screened based on the particle size; bagging and packaging the screened catalyst, and transferring the catalyst to designated areas. The drying temperature is controlled through a dryingoven, so that the drying efficiency is higher, and when the catalyst is crushed, the catalyst is screened, so that the obtained catalyst basically meets the particle size requirement, and the processing quality of the catalyst is improved.

Description

technical field [0001] The invention relates to the field of slurry bed residue oil hydrogenation conversion technology, in particular to a catalyst production method for slurry bed residue oil hydrogenation conversion technology. Background technique [0002] Slurry bed residual oil hydroconversion technology has been paid more and more attention in petroleum production, and in this technology, the use of catalyst is very important. There are mainly three types of catalysts used in the slurry bed hydrogenation process, namely: solid powder catalysts, water-soluble catalysts, and oil-soluble catalysts. [0003] In the existing production process, the raw materials are mainly placed in the reactor for stirring and reacting, and after the reactants are obtained, they are dried and pulverized to obtain the final catalyst. However, during drying, the temperature will affect the drying efficiency, and there is a lack of screening measures during pulverization, which makes it dif...
