1 神华煤直接液化项目必威体育精装版进展 Recent Progress of Shenhua Direct Coal Liquefaction Project 舒歌平 Shu Geping 中国神华煤制油化工有限公司 China Shenhua Coal to Liquid and Chemical Co., Ltd. 2014年3月 March 2014 2 一、神华煤直接液化工艺 I. Shenhua Direct Coal Liquefaction Process 3 一、采用自主知识产权的863液化高效催化剂 I. The 863 highly-efficient Liquefaction Catalyst with Independent IPR Employed ? 863 催 化 剂 价 格 低 、 活 性 高 、 添 加 量 少 ， 油 收 率 高 。 The 863 catalyst is of low cost, high activity, low volume of addition, and high oil yield. 4 二、全部采用预加氢的供氢溶剂 II. An hydrogen donating solvent that is pre-hydrogenated is used in full ? 循环溶剂采用预加氢工艺，溶剂性质稳定 ,溶剂供氢性能好。The solvent recycling process employs pre-hydrogenation; the solvent property is stable, the hydrogen donating performance of the solvent is outstanding. ? 供氢性循环溶剂的组成上有所创新，更有利于生产合格的柴油。The composition of hydrogen donating solvent cycling is innovative, and helpful for producing on-spec diesel. 5 三、采用强制内循环的悬浮床反应器 III. Ebullating Bed Reactor with Forced Internal Circulation ? 通过进料温度控制反应温度，反应器内液速高，反应器内没有矿物质沉 积 。 The reaction temperature is controlled by feeding temperature; the liquid velocity within the reactor is high; there is no mineral sedimentation within the reactor. 6 四、采用成熟的减压蒸馏固液分离技术 IV. Proven Vacuum Distillation Technology for Separation of Solid and Liquid phases ? 减压蒸馏溶剂不含沥青，为进一步提高溶剂的质量提供了可能。The vacuum distillation solvent does not contain bitumen, offering the possibility for further upgrading of the solvent quality. 7 五、溶剂加氢第一次采用悬浮床加氢反应器 V. Ebullating Hydrogenation Reactor is Employed for the First Time for Solvent Hydrogenation ? 由于采用悬浮床反应器，催化剂每天更新，加氢深度稳定。Thanks to the ebullating bed reactor employed, the catalyst is replaced every day, with stable hydrogenation degree. 8 二、示范工程概况 II. Overview of the Demo Project 9 ? 2004年8月动工，2008年5月完成。 Construction was kicked off in August 2004, and completed in May 2008. ? 液化原料煤：6000t/d The rate of feed coal to be lique
