Coal is the dominant fuel in China to provide primary energy, and 70% of polyvinyl chloride is produced from coal-based CaC2. CaC2 reacts with water to produce acetylene and calcium carbide slag (CCS) as a solid waste for polyvinyl chloride production. Approximate 40 million tons of dry CCS are generated annually in China, among which only a small part is used in cement …

Cryogene opslag. Bij cryogene energieopslag (Cryogenic Energy Storage / CES of Liquid Air Energy Storage / LAES) wordt omgevingslucht afgekoeld tot -195°C zodat deze vloeibaar wordt.Water (H²O en koolstofdioxide (CO²) zijn vooraf uit de lucht gehaald omdat deze anders zouden bevriezen.
As an important raw material, acetylene can be used to produce many chemicals [[1], [2], [3]] and products such as polyvinyl chloride (PVC), and it is known as the mother of the …
A type of calcium coke was developed for use in the oxy-thermal process of calcium carbide production. The calcium coke was prepared by the co-pyrolysis of coking coal and calcium carbide slag, which is a solid waste generated from the chlor-alkali industry. The characteristics of the calcium cokes under different conditions were analyzed experimentally …
