Title:
PREPARATION METHOD FOR POLYVINYL CHLORIDE-BASED CARBON POWDER
Document Type and Number:
WIPO Patent Application WO/2020/108535
Kind Code:
A1
Abstract:
A preparation method for the polyvinyl chloride-based carbon powder, specifically comprising: taking the polyvinyl chloride powder as the raw material, taking quaternary ammonium salts as a catalyst, removing a part of hydrogen chloride in an alkaline solution, performing cross-linking and curing, and performing thermolysis to obtain the carbon powder. The preparation method is simple in process, and cheap in raw materials. Carbon powder particles can maintain the shape of the polyvinyl chloride powder particles. The method has wide application prospects in the fields of catalysis, electrochemistry, and adsorption separation.
