中国煤制油技术取得突破 中科院技术助力煤炭清洁利用

国际在线报道(记者 柳青):中国是一个煤炭生产与消费大国,地下拥有相对丰富的煤炭资源,煤炭是中国最重要的基础能源,在国家转型发展的背景下,对能源的清洁利用率也提出了更高的要求。中科院山西煤化所煤化油技术近年来取得突破,并在宁夏、山西、内蒙古等地实现规模化投产,为煤炭的可持续利用提供了可靠路径。

2016年12月,位于宁夏回族自治区银川市的神华宁煤每年400万吨煤制油工程实现一次性投料试车成功,生产出了高品质的柴油、石脑油、蜡等产品。煤制油技术项目团队带头人,中国科学院山西煤化所煤炭间接液化国家工程实验室主任李永旺介绍说,煤制油规模化生产是一个系统复杂的、高度集成的过程,其中合成气转化为初油品的是最为关键的一步。他表示,他和他的团队研发的工艺技术具有突出优势,使中国进入到少数掌握煤制油工业化技术的国家的行列,对中国的能源利用格局具有现实意义。

李永旺说:“首先工艺路线完全不一样,催化剂不一样 最关键就是催化剂,其他技术用铁 我们一吨催化剂生产 两三百吨油 我们这一吨催化剂生产一千多吨油。我们所谓的先进性就是成本低,产出高。通过这样的生产途径,一方面是煤炭的污染物通过生产过程控制住,收集回来,另一方面,产出的产品硫、氮基本没有,这个产品到我们国家的供应市场上,可以有效地补足油品提升的工作。”

据了解,这套煤制油技术生产的高清洁油品无硫、无氮、低芳,优于京VI和欧V标准,除了神华宁煤项目之外,位于内蒙古杭锦旗和山西潞安的百万吨级煤制油装置已经建成,近期即将投产。李永旺表示,煤制油技术的大规模商业化推广是对石油基油品的有效补充,是传统能源向可再生能源供应系统转变的重要过渡。他认为,煤制油技术在中国的成功应用,为中国解决能源可持续供给问题,生产高品质马达燃料和化学品,开辟出了一条新通道。

李永旺表示:“比如说,我们的能源资源,大部分是煤炭,我们自有的储备。作为一个大国,还得有一些途径来依靠自有资源来吧供应问题做好,煤炭就是重要的一块。所以我们这个煤制油路线实际上是除了发电以外,煤炭大量可以应用的另一条途径。”
