Title: Jinguang Zhong: Innovator in Polyvinyl Chloride Production

Introduction

Jinguang Zhong is a notable inventor based in Xiamen, China. He has made significant contributions to the field of chemical engineering, particularly in the production of polyvinyl chloride (PVC). With a total of 3 patents to his name, Zhong's work focuses on innovative methods that enhance industrial processes while minimizing environmental impact.

Latest Patents

Zhong's latest patents include a loop-route production method and system for polyvinyl chloride. This invention relates to the intersecting fields of coal chemicals, polymer materials, and chemical machinery. The method involves reacting limestone and carbon materials in an oxygen-enriched high-temperature furnace to produce calcium carbide and carbon monoxide. Subsequently, acetylene and carbon monoxide are generated from calcium carbide and dichloroethane, leading to the formation of a closed-loop system. This innovative approach not only reduces dependence on oil resources but also eliminates mercury pollution during PVC production.

Another significant patent is the method for preparing vinyl chloride from acetylene and dichloroethane. This method is designed for large-scale industrial production and involves mixing acetylene, dichloroethane vapor, and hydrogen chloride gas in specific molar ratios. The process includes preheating the raw mixed gas, passing it through a catalyst-containing reactor, and subsequently cooling and liquefying the resultant gas. This invention simplifies reactor structures, recycles hydrogen chloride and acetylene, and improves chlorine utilization while completely eliminating mercury contamination.
