天然气制合成油的技术进展

Technology Advances in Production of Synthetic Oil from Natural Gas

天然气制液态烃(GTL)是近年来天然气转化利用研究的主流,国外的Shell、Sasol、Exxon、Syntroleum、Williams等公司都分别开发了各自的GTL专利技术。GTL产品基本上由直链烷烃、烯烃组成,具有无硫、无氮、无金属、无芳烃等特点,是环境友好的油品和化学品。详细综述了合成油催化剂、反应器、GTL技术发展动态等,讨论了GTL的发展趋势,并对我国GTL的研究提出几点建议。

Conversion of natural gas to liquid hydrocarbon (GTL) is one of the main trends in the study of natural gas utilization. Some corporations, such as Shell, Sasol, Exxon, Syntroleum, and Williams, have developed their patent techniques on GTL.The products from GTL include fuel oil,base oil for lubricant,and other chemicals,which are environmentally friendly due to their few S, N, metal, and aromatic hydrocarbon content. The recent advances in catalysts and reactors for GTL are reviewed, and the trend of GTL in the future is discussed. Some suggestions on GTL development in China are proposed.
