Coalescence filler for alkylating acid hydrocarbon separation

Abstract

The invention discloses a coalescence filler for alkylating acid hydrocarbon separation, and relates to the technical field of acid hydrocarbon separation. The coalescence filler is prepared from the following raw materials in parts by weight: 25-30 parts of ultrafine polytetrafluoroethylene powder, 10-15 parts of chloroprene rubber, 10-15 parts of polyvinyl acetate, 8-12 parts of polyethylene terephthalate, 6-11 parts of linear low-density polyethylene, 5-9 parts of pozzolan, 5-9 parts of activated clay, 4-8 parts of polyvinyl butyral, 4-8 parts of hydrogenated rosin glyceride, 3-6 parts of petroleum coke powder, 3-6 parts of fine ceramic powder, 2-4 parts of asbestos wool, 2-4 parts of potassium cetyl phosphate, 2-4 parts of epoxidized soybean oil, 1-2 parts of tea seed powder, 1-2 parts of nano-rubber powder, 1-2 parts of lanolin, 0.5-1 part of zinc oxide and 0.5-1 part of nano-graphite powder. The coalescence filler provided by the invention has good processing formability, can be processed into various shape structures according to needs, has excellent acid resistance, can be recycled and reused for several times after being rinsed, can rationally utilize resources, and can reduce separation costs.

Description

Technical field: [0001] The invention relates to the technical field of separation of acid hydrocarbons, in particular to a coalescence filler for separation of alkylated acid hydrocarbons. Background technique: [0002] Concentrated sulfuric acid is used as a catalyst in sulfuric acid alkylation, and the catalyst is in direct contact with the liquefied gas raw material, so the reaction product needs to be separated from the concentrated sulfuric acid catalyst for acid hydrocarbons. Currently commonly used acid-hydrocarbon separation equipment adopts static precipitation, or sets simple internals in the container for separation, and the separation effect is not good. Patent CN 205461143U discloses an alkylation acid-hydrocarbon separator, which includes a reactor cylinder. The inside of the reactor cylinder is equipped with a distribution plate and coalescing packing to strengthen the separation of acid-hydrocarbon mixture, so that the acid that enters the coalescing packing...
