| Drying of carbon-based raw materials in order to obtain dried carbon-based raw materials; The dried carbon-based raw materials and calcium-based raw materials were crushed respectively to obtain carbon-based particles and calcium-based particles. The carbon-based particles and calcium-based particles were mixed to obtain the mixed materials. The mixed materials are pyrolyzed to obtain high quality tar, high calorific value gas and pyrolytic solid products, which contain quicklime and one of the selected coke, semi-coke and carbon black; And the pyrolytic solid products are input into the arc furnace at a temperature of not less than 450 degrees Celsius for smelting treatment in the arc furnace, and calcium carbide is obtained. This can further improve heat utilization and production efficiency, reduce production costs, reduce energy consumption and pollution |
