2、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。关键词:重油;脱金属;膜分离;催化加氢;超声波;微生物法中图分类号:TE624文献标志码:A文章编号:1000-6613(2016)s2-0127-05DOI:10.16085/.jissn.1000-6613.2016.s2.021Progressofresearchond
