Method for producing blocky calcium oxide by utilizing carbide slag
The invention belongs to the field of chemical production, and discloses a method for producing blocky calcium oxide by utilizing carbide slag. The method comprises the following steps: 1, adding water into an adhesive to obtain an aqueous adhesive solution; 2, adding the aqueous adhesive solution into the carbide slag, and uniformly mixing to obtain a mixture; and 3, carrying out compression molding on the mixture, drying at room temperature, drying, and calcining to obtain the catalyst. Carbide slag generated in the process of producing acetylene from calcium carbide is used as a main raw material, cyclic utilization of the carbide slag is achieved, the problems of energy and environment in the coal-based calcium carbide industry are solved, and the maximum load of calcium oxide obtainedthrough cooperation with disodium hydrogen phosphate and a sodium dihydrogen phosphate adhesive can reach 85.8 N or above.
本发明属于化工生产领域，公开了一种利用电石渣生产块状氧化钙的方法，包括以下步骤：步骤1，向粘合剂中加水，得粘结剂水溶液；步骤2，向电石渣中加入粘结剂水溶液，混合均匀，得混合物；步骤3，将所述混合物压制成型，室温干燥，烘干，煅烧，即得；以电石生产乙炔过程产生的电石渣为主要原料，实现电石渣的循环利用，解决煤基电石行业的能源与环境问题，且配合磷酸氢二钠、磷酸二氢钠粘结剂所得的氧化钙的最大荷载能达到85.8N以上。
