Calcium carbide sludge from acetylene production and other industrial processes 1,2 has a high solid content, and its apparent viscosity can reach several thousand Pascal seconds. These calcium carbide sludge tailings in industry are also referred to as "dense paste" in this article to describe a sort of material that consists of …

Soluble calcium ions can be derived from carbide sludge for biocement production. Urine serves as the sole growth medium for urease producing bacteria cultivation. Urine-contained urea is a substitute of commercial urea for biocementation. The ingredients from carbide sludge and urine can be used to produce biocement.

Introduction. Calcium carbide (CaC 2), regarded as one of the basic pillars of the chemical parental materials before the maturity of petroleum refining technology in the world, still receives a booming requirement for producing acetylene in China.In 2020, the yield of CaC 2 hits 27.92 Mt with the corresponding production capacity standing at …

Raw acetylene, as it exits a wet calcium carbide generator, contains several impurities. One of these impurities is ammonia. The ammonia content in generated acetylene results from the reaction of calcium cyanamide with water during the production process. Upon compression, ammonia becomes a thick, black, semi-loquacious compound.

Products Details. Calcium carbide is a chemical compound mainly use industrially in the production of acetylene and calcium cyanamide. When pure, it is colorless, however, pieces of technical-grade calcium carbide are grey or brown. In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic.

Calcium carbide residue (CCR) is a solid waste resulting from acetylene gas production. In this study, CCR was used as an alkali activator to prepare fly ash (FA)-based geopolymers without any alkali supplementation. We studied the factors (FA/CCR ratio, curing temperature, and water/binder ratio) influencing the mechanical property of …

Carbide lime waste, a by-product of acetylene production, and industrial hydrated lime were investigated. The materials are similar in chemical and mineralogical compositions, mainly composed by Ca(OH) 2 with minor portions of CaCO 3, except for the presence of carbon as graphite particles and amorphous films in the …
