【摘要】 长链烷烃异构化是重要的石油炼制过程,在提高汽油辛烷值、降低柴油凝点、改善润滑油低温流动性能等方面有着广泛的应用;同时,它也是满足未来需求,化学合成清洁燃料的关键技术,可应用于生物柴油生产、费托合成蜡制高品质柴油等过程。具有择形功能的负载型贵金属分子筛催化剂是长链烷烃异构化催化过程的技术核心。在对相关分子筛合成所涉及的科学和技术问题以及催化剂构效关系的深入研究基础上,作者开发出具有自主知识产权的润滑油基础油加氢异构脱蜡催化剂及技术,在中国石油大庆炼化20万吨/年高压加氢装置上成功实现工业应用。本文围绕长链烷烃异构化催化过程所涉及的科学和技术问题,主要介绍作者在催化剂构效关系、分子筛材料的新合成方法和合成机理、新型分子筛合成等方面取得的研究进展。此外,针对该过程潜在的应用方向,还将介绍油脂加氢异构制生物柴油/航空煤油的研究进展。更多还原

【Abstract】 Hydroisomerization of hydrocarbons is an important process in petroleum refining, mainly used for improving the low-temperature fluidity of high quality fuels and lubrication oils. The stateof-the-art hydroisomerization catalysts are usually shape-selective molecular sieves based precious metal catalyst. Hydroisomerization of long-chain alkanes can also be employed for producing high quality synfuels from FT wax and natural lipid, and are of essential importance for the alternative energy production. Technology innovation relies on novel catalyst design and the invention of new materials. The development of catalysts must be the basis of a good understanding of reactivity of various zeolites and a novel concept of catalyst design. Basing on a good understanding of reactivity of various zeolites and a novel concept of catalyst design, we have developed a robust Paraffin IsoConversion(PIC) catalyst which has been commercialized in a 200 k T/a II/III base oil unit of a refinery of Petro China.The report describes the research on the hydroisomerization catalyst and mechanistic studies on the synthesis of relevant molecular sieves, and illustrates a prospect of hydroisomerization process on fungible biodiesel production.更多还原
