| 摘要 |
The present invention relates to the fields of fuel industry and utilization of waste from woodworking, paper and pulp, coal and peat mining industries; it represents composition for manufacture of fuel briquettes comprising crushed secondary carbon-containing feed stock: petroleum pitch, coal pitch, coal dust, crushed coal product, crushed peat, wood shavings, sawdust or their mixes and binder: lignin-containing product selected from the group: lignin, lignosulfonate, hydrolytic lignin, black sulfate liquor or their mixes, or mix of one or several above enumerated lignin-containing products with a-cellulose. Composition allows manufacture of ecologically clean fuel briquettes from practically any solid secondary carbon-containing feed stock featuring high calorific value (up to 7000 cal/g), density of 1.04-1.18 g/cm<3> and ash content of 0.8-1.2 %. |
