摘要： 利用2 kg实验焦炉,进行湿煤炼焦和干煤炼焦的对比实验,考察产物分布特性、焦炭质量特性、焦油和煤气组成特性等.研究表明,与炼焦煤水分为10%的湿煤炼焦相比,干煤炼焦具有如下特性:炼焦煤堆密度增大,所得焦炭、焦油和煤气的产量增加,焦化水的产量减少;焦炭、焦油和煤气的收到基产率增加,焦化水的收到基产率减少;焦炭和焦油的干基产率增加,煤气的干基产率减少;焦炭的孔体积减少,强度指标明显改善;焦油中芳香烃含量增加,烯烃含量减少;煤气中氢气含量增加,甲烷含量减少.

Abstract: Using a 2 kg experimental coke oven, the coking processes from wet coal and from dried coal were investigated contrastively including the characteristics of the products, coke quality and composition of tar and gas, where the moisture of wet coal is 10%. The results showed the higher stack density of dried coal and the following characteristics of the coke with dried coal as raw material. The output and the receivable basic yields increased with water content decreased, but, in view of the drying-based yield, the coke and tar increased while the gas decreased. The pore volume of coke decreases with its strength index improved obviously, and the aryl organic compound in tar increased with alkene decreased. And in the gas H2 increased with CH4 decreased.
