中低温煤焦油加氢技术进展

Hydrogenation process of medium & low temperature coal tar

简述了中低温煤焦油与其加氢产品油的特性及近年来主要的4种焦油加氢工艺技术。对10万t/a焦油加氢项目进行经济效益分析,结果表明,项目净利润为10391.7万元/a,税后投资回收期为5.4年,经济效益良好。

This paper outlined the behaviors of medium and low temperature coal tar, its hydrogenated oil products and the four main coal tar hydrogenation processes in recent years. It also analyzed the economic benefit for a project of 1M t/a coal tar hydrogenation. The result shows a good economic benefit,i, e. the net profit is 103 917 000 yuan per year and the payback period after tax is 5.4years.
