摘要/Abstract

摘要： 利用自制油酸改性Fe2(MoO4)3催化剂，将其用于新疆克拉玛依稠油水热催化降黏的研究，考察了催化剂加入量、反应温度、反应时间对稠油水热催化改质降黏的影响，得到最佳工艺条件为：催化剂添加量（w）0.4%，反应温度240 ℃，反应时间36 h，此时降黏率为61.21 %。稠油族组成分析结果表明有13.2%（w）的稠油重组分裂解成轻组分，这是稠油黏度降低的主要原因。通过进一步对反应前后稠油重组分进行元素分析、FT-IR、1H NMR谱图分析，发现稠油重组分在反应过程中存在脱硫、脱氮、加氢开环、支链断裂等反应。

Abstract: The oleic acid modified Fe2(MoO4)3 catalyst was prepared and used in catalytic visbreaking by aquathermolysis for Karamay heavy oil. The effects of catalyst dosage, reaction temperature and reaction time on viscosity reduction were investigated. The optimum process conditions were 240 ℃, reaction time of 36 h, and 0.4% of catalyst. At the optimal conditions, the viscosity reduction rate was 61.21%. The SARA analysis indicated that 13.2% of the large hydrocarbon molecules were significantly cracked to form light components, which was the main reason for the viscosity reduction of heavy oil. The compared results of FT-IR, 1H NMR analysis of the heavy components of heavy oil before and after the reaction indicated that desulfurization, denitrogenation, ring opening, branch chain breaking and other reactions occurred in heavy components.

Key words: heavy oil, catalytic visbreaking, oleic acid modification
