摘要: 我国来自炼油厂和石化装置的碳四(C4)烃资源非常丰富,与此同时,C4烃用作传统液化石油气燃气的需求量正逐渐减少,C4烃资源综合利用成为企业的关注热点。本文介绍了国内外C4烃转化与利用技术的开发进展及工业应用情况,包括丁烯异构化、丁烯歧化、C4烯烃催化裂解、异丁烷脱氢、异丁烯制甲基丙烯酸甲酯(MMA)、C4烃芳构化与烷基化等。认为对炼化一体化企业而言,将炼油厂C4和裂解C4整合在一起,应用增产低碳烯烃、醚后C4生产高辛烷值汽油组分、C4组分相互转化以及向下游高附加值产品延伸等技术,未来将具有较好的发展前景,不仅可为市场提供所需的燃料与化学品,而且有利于提升企业经济效益。

Abstract: Comprehensive utilization of C4 hydrocarbons is now a hot research topic because of abundant supply of C4 fractions from refineries and petrochemical plants as well as its reduced demand as LPG fuel. Development progress and commercial application of technologies for converting and utilizing C4 hydrocarbons were discussed, including butenes isomerization and disproportionation, C4 olefin cracking, butane dehydrogenation, iso-butene to MMA, C4 aromatization and alkylation. For refinery-chemical integrated plants, it will be prospective to combine C4 fractions from refineries and cracking plants, and use advanced technologies to increase light olefins production, produce high octane value gasoline, and extend downstream to high value-added products. In this way, they can not only supply fuels and chemicals to the market, but also increase economic benefit.

Key words: C4 hydrocarbon, comprehensive, utilization, progress, perspective
