摘要/Abstract

摘要： 重油的开采与加工日益成为石油化工行业关注的焦点，然而其深加工利用受到内部高含量金属的影响。为此，本文介绍了重油中金属的来源、存在形态及其对石油加工利用的危害。综合对比分析了国内外重油脱金属常用的几种方法。膜分离法虽然工艺简单、经济环保，但该技术不成熟，难以满足工业应用；催化加氢法金属脱除率高，但易受氢源及催化剂性能限制，且工业成本较高；化学法易于操作但副反应多且易污染环境；超声波脱金属法节能降耗明显，脱金属率高，但大型的超声装置如何应用于工业生产，尚需进行深入研究；微生物法投资少，适应性强，但难以筛选合适的菌种。总之，由于重油自身的特性，单一的脱金属技术难以获得佳绩，联合脱金属将成为一种发展趋势。

Abstract: The exploitation and upgrading of heavy oil has increasingly gained great attention.However,its utilization is limited seriously to its high metal content.Then,the source and forms of metal in heavy oil and its hazards for the processing of petroleum are summarized in this paper.Methods commonly for demetalization in domestic and overseas are introduced and compared in detail.Membrane separation method is friendly to environment and is operated simply,but it is difficult to meet industrial application due to its immature technology.Catalytic hydrogenation process shows high demetalization efficiency.However,it is restricted by hydrogen source and properties of catalyst,and its cost is too high.Chemical method can be operated simply,whereas,it is easy to produce byproduct and pollute the environment.Demetalization under ultrasonic radiation process costs less energy and has high demetalization efficiency,but it is necessary to make further research on how to apply the large ultrasonic device in industrial production.Microbial method has the characteristic of less investment and strong adaptability,it is difficult to filter suitable strains.Because of the character of heavy oil,a single demetalization technology is not easy to get success and demetalization technology in joint will become a development trend.

Key words: heavy oil, demetalization, membrane technology, catalytic hydrogenation, ultrasonic radiation, microbe
