摘要

Briquetting is regarded as one of the best methods of processing coke fines. The basic physicochemical properties of the following materials are determined: coke, petroleum coke, and sintering additives in the form of pitch derived from various hydrocarbons (tar sludge, heavy gas oil from catalytic cracking, and heavy pyrolytic tar). The clinkering properties of composites are determined by a modified Roga method as a function of the binder content. Pitch from tar sludge is selected as the best sintering additive in the production of coke fines and petroleum coke fines. Composites with high strength are obtained over a wide range of concentrations of the sintering additives employed. For example, for grade B petroleum coke, the content of pitch from sludge in the composites is 5.0–52.5 wt %; for regular coke, it is 15.0–55.0 wt %.
