tar paper

In this paper, the fusel was added in bituminous pyrolysis for the first time. The pyrolysis of shenmu bituminous coal was investigated on a fixed-bed reactor. We hoped to improve the situation that the coal tar yield of the traditional pyrolysis process was low.

本文首次将杂醇引入煤热解中，利用固定床热解装置对神木烟煤进行研究，希望改善传统热解工艺焦油产率较低的状况。

Therefore, based on the least squares support vector machine theory, this paper proposes a model for catalytic cracking of tar removal straw gasification, and verifies the feasibility of the model.

因此本文依据最小二乘支持向量机理论建立了秸秆气化焦油催化裂解脱除过程的模型，并验证了模型可行性。

This paper introduces the process of absorbing benzene from coal gas by tar wash oil in coking plants. The main cause of low yield of the crude benzene is that the distillation range of the recycled wash oil is too low before 270 ° C.

介绍了焦化厂焦油洗油吸收煤气中苯的工艺流程，分析了造成粗苯产量低的主要原因是循环洗油270℃前馏程偏低。
