为了提高江汉油田直馏混合溶剂油的质量 ,采用催化加氢的方法脱除油中的芳烃 ,应用Ni -Al催化剂 ,在10 0mL加氢反应装置上分别考察了不同操作条件下江汉油田直馏混合溶剂油催化加氢脱芳烃的效果 .结果表明 :在反应压力为 0 .3～ 1.0MPa ,氢油体积比为 6 0～ 90 ,反应温度为 130～ 16 0℃ ,空速为 1.0～ 2 .5h- 1 较宽的操作条件下 ,催化加氢脱芳烃的效果均较好 ,加氢后油中苯的质量分数小于 0 .0 2 % ,甲苯的质量分数小于 0 .0 5 % ;应用该方法均可使分馏后生产的各类溶剂油质量符合国家质量标准
In order to improve the quality of straight-run mixed solvent oil in Jianghan Oilfield, catalytic hydrogenation was used to remove aromatics from the oil. The Ni-Al catalyst was used in a 10OmL hydrogenation reactor to investigate the effects of straight run The results showed that when the reaction pressure was 0.3 ~ 1.0MPa, the volume ratio of hydrogen to oil was 60 ~ 90, the reaction temperature was 130 ~ 160 ℃, the space velocity was 1.0 ~ 2 .5h-1 under a wide operating conditions, the catalytic hydrodearomatization are better, the hydrogen content of benzene in the oil after the mass fraction of less than 0.02%, toluene mass fraction of less than 0.05%; application The method can make the quality of various types of solvent oil produced after fractionation meet the national quality standards
