Use of Biomass and Waste Tires to Facilitate the Use of HDPE in Coking
This work examines the role of various wastes such as pine sawdust, tire crumbs, and hydrochar from pine sawdust in reducing the deleterious impact of high-density polyethylene (HDPE) on coke contraction during coking. Contraction assessed using the Koppers-INCAR test was used as an indirect measurement of coking pressure. The Koppers-INCAR contraction of ternary blends containing coal, HDPE, and one of the other additives was tested together with their devolatilization in a thermobalance. The existence of synergism between the additives was examined to determine whether there were both positive and negative interactions between HDPE and other additives. The temperature corresponding to a 2% conversion increased with the use of additives; this was related to the degree of dangerousness of the blends. In addition, the effect of the additives on coal fluidity and coke quality was tested.
