陕北煤低温干馏炉气综合利用技术

为了有效利用陕北煤低温干馏炉气,尤其是干馏炉气中附加值较高的H2,结合陕北地区煤低温干馏炉气的利用现状,分析了国内外CO变换制氢技术、变压吸附剂发展技术及变压吸附制氢工艺的研究进展,提出了采用CO变换技术先将煤低温干馏炉气中的CO组分转变为H2,通过选择适宜的变压吸附剂,再利用变压吸附技术分离提纯干馏炉气中的H2,最终将低温干馏炉气中H2应用于煤焦油加氢产业的方法。结果表明:选择市售吸附剂,通过对变压吸附工艺条件的研究开发,进行低温干馏炉气的变压吸附制氢,可实现低温干馏炉气的综合利用。 To use low temperature coke oven gas effectively,especially H2 with high added value,combining its utilization status in Northern Shaanxi,analyse CO conversion manufacturing H2 technology,the development of adsorbent and research progress of purifying hydrogen for PSA(pressure swing absorption) at home and abroad.Provide that,first,convert CO in coke oven gas into H2,then separate and purify H2 with PSA and suitable adsorbent.The treated H2 could be used in coal-tar hydrogenation industry,which is an efficient utilization way.The results show that,by selecting commercially available adsorbents and adopting PSA technology,the low temperature coke oven gas could be effectively used by manufacturing H2
