浆态床渣油加氢技术现状与展望

近年来国内原油进口依存度一直处于高位，原油资源需要高效利用。重质馏分油特别是渣油的高效转化至关重要，浆态床渣油加氢技术由于其能加工劣质原料且转化率高，是将重油转化为高价值运输燃料和石化产品的较好选择。重点介绍了国内外典型浆态床渣油加氢技术，包括委内瑞拉国家石油公司的HDH-Plus技术、美国环球石油公司的Uniflex技术、美国雪佛龙鲁姆斯公司的LC-Slurry技术和VRSH技术、意大利埃尼公司的EST技术、中石化石油化工科学研究院有限公司的RMAC技术，比较了上述技术的特点，分析其技术难点，建议加强浆态床渣油加氢工艺、工程和催化剂等方面的研究。

STATUS AND PROSPECT OF SLURRY BED RESIDUE HYDROCRACKING TECHNOLOGY

In recent years, the domestic demand of crude has depended on importing foreign crude at a high level, and the resource of crude needs to be utilized efficiently, slurry bed hydrocracking technology is a good choice to convert heavy oil into high-value transportation fuel and petrochemical products because of its high conversion rate and low quality feedstock. Several slurry bed residue hydrocracking technologies were introduced as follows: HDH plus technology of PDVSA, Uniflex technology of UOP, LC-Slurry technology and VRSH technology of CLG, EST technology of Eni, RMAC technology of RIPP. The technical characteristics of above processes were compared, and the technical difficulties of slurry bed residue hydrocracking were analyzed. It is suggested that the study of slurry bed residue hydrotreating process, engineering and catalyst should be strengthened．
