摘要:
以磷酸为酸性助剂,对通用型加氢处理催化剂进行了酸改性,采用X射线衍射仪、N2物理吸附仪、X射线电子能谱仪等对制备的系列加氢脱酸催化剂进行了表征,并在固定床加氢装置上对其性能进行了评价。结果表明:磷改性后,催化剂的强度、堆积密度、弱酸性均增加,比表面积和孔容均降低;当磷质量分数高于1.50%时,催化剂中会出现磷酸铝晶型;4种催化剂中,磷质量分数为0.75%时,制得的催化剂具有最优的脱酸、脱硫、脱氮性能,在反应压力为3 MPa,反应温度为280 ℃的条件下,其脱酸、硫、氮率依次为99.1%,44.72%,10.8%,油品酸值可降至0.028 mg/g。
Abstract:
A series of hydrogenation deacidification catalysts that modified by phosphoric were characterized by X-ray diffraction instrument, N2 adsorption-desorption instrument, X-ray electron spectrometer, and its performance were evaluated in the fixed bed hydrogenation device. The results showed that after phosphorus modification, the attrition,bulk density and weak acid of the catalyst had increased, its specific surface area and pore volume had decreased. When mass fraction of phosphorus was higher than 1.50%, the crystal form of aluminum phosphate would appear in catalyst. Among four kinds of catalysts, the catalyst with phosphorus mass fraction 0.75% had the best acid, desulfurization and denitrification performance. Under the conditions of reaction pressure 3 MPa, reaction temperature 280 ℃, its deacidification, desulfurization,denitrification rate was 99.1%, 44.72%, 10.8%,oil acid value could be dropped to 0.028 mg/g.
