摘要

Every year the coking industry produces a significant amount of tarry and other wastes in byproducts plants. For the most part these wastes have not been put to any practical use. In addition, an integrated factory produces several waste oils which differ in composition and quantity, e.g., wastes from the steel rolling-mill process. In this work, the possibility of using such waste materials as binders in a partial briquetting process for metallurgical coke production is explored. By means of this coking procedure, a strong metallurgical coke not inferior in quality to coke from conventional coal blends is produced at pilot and semi-industrial scales. The use of such wastes, some of which are classified as hazardous materials, will avoid the need for dumping, thereby contributing to the protection of the environment as well as reducing the costs related to waste disposal.
