COKE-MAKING PROCESS AND COKE FUEL PRODUCED BY SAME

摘要

Coke is made from wastes such as fruit and vegetable peels, sawdust, straw, newsprint and whey liquid by decarboxylating and carbonizing these materials in the liquid aqueous phase under pressure. The coke produced is light and fluffy, easy to ignite and has a sulfur content below 0.5 percent by weight, a density of about 1.3 percent, a hydrogen content of at least 4.9 percent weight percent, a high-oxygen content, and a surface area ranging from 8 to 26 sq. meters per gram. These properties make the coke particularly useful in the manufacture of charcoal briquets, as fuel for orchard heating and wherever it is desired to avoid air pollution.
