The chemical reaction of the solid calcium carbide to the highly flammable acetylene gas production is shown in equation 1 [30], [31]. (1) CaC 2 + 2 H 2 O → C 2 H 2 + Ca (O H) 2. based on this equation, for each gram of calcium carbide, both 0.5 g of acetylene gas and 1.16 g of CCR are produced [32].
Calcium carbide slag (CCS) is a solid waste from the hydrolysis of calcium carbide to obtain acetylene gas, with Ca(OH) 2 as the main component. Acetylene gas can be further used to prepare polyvinyl chloride(PVC). However, nearly 20 tons of CCS are produced in each ton of PVC production.
Formation of calcium carbide. The calcium carbide production technology in the industry was invented in 1892. Its production principle is that calcium oxide and coke react at a high temperature above 2000 °C generated by an arc to produce molten calcium carbide (CaC 2).This process is called the electro-thermal method or arc method [] that is shown in Eq.
Aiming to make full use of three kinds of solid wastes from calcium carbide industry, this paper first investigated elements and mineral compounds of them through inductively coupled plasma and X-ray diffraction (XRD). The three solid waste samples, removed dust (RD), coke dust (CD) and purified dust (PD), have higher Ca/S molar ratios than …
The calcium carbide (≥ 98%) used in this study was purchased from Shanghai Macklin Biochemical Technology Co., Ltd., China. The lump calcium carbide was crushed by a high-speed crusher and then passed through an 80–120 mesh sieve. The obtained calcium carbide powder was recorded as CC and placed in a
