煤富氧低温干馏实验研究

EXPERIMENTAL STUDY ON COAL OXYGEN ENRICHED LOW-TEMPERATURE CARBONIZATION

通过对陕北榆林地区煤低温干馏应用现状的实地考察,发现干馏过程产生的煤气热值偏低,影响焦油产出和煤气高效利用.为优化生产工艺,提出富氧干馏实验方案.通过理论计算及实验数据分析,结果表明,富氧干馏完全可行,富氧干馏能够降低煤气中氮含量,提高有效可燃成分含量,使煤气热值大幅度提高,解决了由于低热值煤气无法有效利用而放空所造成的环境污染和资源浪费问题.

In view of that the gas calorific value is low, the experimental program of the oxygen enriched carbonization is proposed based on on-the-spot investigation of coal low-temperature carbonization application present situation in Yulin Northern Shaanxi. The theoretical calculation and the analysis of the experimental data have proved that the oxygen enriched carbonization is feasible. The oxygen enriched carbonization can decrease the nitrogen content and increase the effective combustible component content in the gas, it causes the gas calorific value significantly increased and have solved the problem of environmental pollution and resource-wasting because the low calorific value gas was utilized effectively and released into the air.
