Porous propping agent combination and preparation method thereof

Abstract

The invention discloses a porous propping agent combination and a preparation method thereof; the propping combination comprises a porous propping agent, sulfur which occupies 20-300 percent of the weight of the porous propping agent, organic solvent which occupies 0-50 percent of the weight of the porous propping agent and auxiliary agent which occupies 0-25.0 percent of the weight of the porous propping agent. The propping agent combination is suitable for hydrogenation disposal process. The porous propping agent combination provides vulcanizing agent for the oxidated hydrogenation catalyst, shortens the commencement time of the device, improves the production efficiency, overcomes the defects of pre-vulcanization in the device, and can solve the problem of concentrative heat discharge of pre-vulcanized catalyst outside the device. Furthermore, the sulfur introduced in the porous propping agent is mainly arranged in holes of the propping agent, increases no volume of the propping agent, thus affecting no disposal quantity of the device further.

Description

technical field

[0001] The invention relates to a porous proppant composition and a preparation method thereof, in particular to a porous proppant composition used in a hydrogenation process and a preparation method thereof. Background technique

[0002] Hydrogenation catalysts used in industry are generally supported by refractory oxides such as alumina, silica-alumina, and molecular sieves, and one of Group VIB metals (such as molybdenum, tungsten) and Group VIII metals (such as cobalt, nickel) One or several are active metal components, and these active metal components are dispersed on the carrier in an oxidized state, and during the hydrogenation reaction, the active metal components of the catalyst are in a sulfide state (the metal exists in the form of sulfide: co 9 S 8 、MoS 2 、Ni 3 S 2 、WS 2 etc.) have higher activity and stability. Therefore, presulfidation is required to convert the active metal from an oxidized state to a sulfided state before the catalyst ...
