METHOD FOR THE PRODUCTION OF CALCIUM CARBIDE ON AN INDUSTRIAL SCALE IN AN ELECTRIC LOW-SHAFT FURNACE

摘要

The invention relates to a method for the production of calcium carbide on an industrial scale in an electric low-shaft furnace using PVC-containing plastic waste. The invention is characterized by a) thermally decomposing the PVC-containing plastic waste in the temperature range of 250 to 500°C to form HCl gas and a carbonaceous residue and b) using the carbonaceous residue formed in step a) as a feed material in the production of calcium carbide.
