Novel catalyst for calcium carbide production process

Abstract

The invention relates to a novel catalyst for a calcium carbide production process. The catalyst is formed by compounding and mixing an activator, a sulfur fixing agent, a combustion improver and a dispersant, wherein the catalyst is prepared from the following raw materials in percentage by mass: 55 to 75 percent of the activator, 15 to 28 percent of the sulfur fixing agent, 5 to 20 percent of the combustion improver and 1 to 3 percent of the dispersant. The novel catalyst uses a macromolecular dispersant with good chemical stability, does not contain a halide ion corroding a device, can be used for improving a reaction rate and lowering a reaction temperature and energy consumption during the production of calcium carbide, is used for effectively fixing sulfur, has good safety performance, does not generate spontaneous combustion, has no toxicity and no corrosivity, and has a quite wide application prospect; the experimental operation is simple and convenient; an addition amount is lower than that of an equivalent ordinary catalyst; the raw materials are cheap and easily obtained, and the energy conservation, the emission reduction, the environmental protection and no pollution in real sense can be achieved by an effect of the novel catalyst.

Description

technical field [0001] The invention relates to the field of calcium carbide production technology, in particular to a novel catalyst for calcium carbide production technology. Background technique [0002] In recent years, China's calcium carbide has developed rapidly and has become the world's largest producer and consumer. In 2010, the world's calcium carbide production capacity was about 27 million t / a, among which, China's calcium carbide production capacity accounted for about 96% of the world's total production capacity. Due to the high energy consumption and heavy pollution in the production process of calcium carbide. Electric furnaces consume a lot of electric heat, and are called "electric tigers". Facing the current energy shortage, how to further reduce electric energy is a top priority for all calcium carbide manufacturers. Against the backdrop of global warming and rising calls for emission reductions, for developing countries, improving energy utilization e...
