在催化蒸馏技术的基础上开发了一种新型临氢催化提馏工艺，用于喷气燃料脱硫醇。该工艺主要的特点是用一个催化提馏塔代替通常使用的反应器和气提塔，在催化提馏塔中气相和液相逆流接触，在催化剂表面上进行临氢反应，反应产物用蒸馏和气提的方法脱除。氢气是反应物，也是气提介质。应用该技术在温度２３０ ℃、压力０．４～２．０ ＭＰａ、空速４～６ ｈ－ １、氢油体积比２０～３０ 的条件下，使阿曼、沙特轻质、伊朗轻质等原油的喷气燃料中硫醇硫含量小于２０ μｇ／ｇ，其它各项指标均符合喷气燃料标准
Based on the catalytic distillation technology, a new type of catalytic hydrogenation distillation process has been developed for jet fuel sweetening. The main feature of this process is to replace the commonly used reactor and stripping column with a catalytic stripping column where gas phase and liquid phase are countercurrently contacted and a hydrogen reaction is carried out on the surface of the catalyst and the reaction product is purified by distillation and stripping Method of removal. Hydrogen is a reactant, also a stripping medium. The technology was applied to make Oman, Saudi Arabia, Iranian crude oil and other crude oil under the condition of temperature 230 ℃, pressure 0.4 ~ 2.0 MPa, airspeed 4 ~ 6 h-1 and hydrogen oil volume ratio 20 ~ 30 Of jet fuel sulfur content of less than 20 μg / g, the other indicators are in line with jet fuel standards
