生物技术脱硫存在的主要问题和发展方向BDS方法中微生物和它们的酶发生催化效率反应来释放硫而不消耗烃,具有投资费用低,运行费用低,可在常温常压下运行,不需加氢等优点。
The main problems and development direction of biological desulfurization BDS method has the advantages of low investment cost, low operation cost, normal temperature and pressure, and no hydrogenation.
目前,很多炼油厂加氢脱硫装置中,采用生物氢联合脱硫装置原设备生产低硫燃料的可行方法。但BDS工业化还存在一些问题,主要是化石燃料中的硫化合物,结构复杂,生物催化剂分解代谢的一些特定的有机硫化合物的作用良好,但其他一些含硫化合物的脱硫作用差。所以,继续探索脱硫范围较广、选择性宽的生物催化剂是研究的方向之一。
At present, it is a feasible method to produce low sulfur fuel by using the original equipment of biological hydrogen combined desulfurization unit in many refinery hydrodesulfurization units. However, there are still some problems in the industrialization of BDS. The sulfur compounds in fossil fuels are complex in structure. Some specific organic sulfur compounds metabolized by biocatalysts have good desulfurization effect, but others have poor desulfurization effect. Therefore, it is one of the research directions to continue to explore biocatalysts with wide desulfurization range and wide selectivity.
目前还有大量的基础研究和应用研究工作要做,未来的微生物脱硫研究将要在以下领域展开∶
At present, there are still a lot of basic research and application research work to be done. The future research on microbial desulfurization will be carried out in the following areas:
采用不同的模型化合物的整方位的研究探讨石油微生物有机硫的脱除技术。目前的有机硫除研究主要集中在噻吩型含硫化合物方面,进一步选择硫醇,硫化物为两个模型化合物进行进一步的研究。
Different model compounds were used to study the removal technology of organic sulfur from petroleum microorganism. At present, the research of organic sulfur removal mainly focuses on thiophene type sulfur compounds. Mercaptan and sulfide are selected as two model compounds for further research.
                             生物脱硫
加强和微生物脱硫过程的规律性和机理的研究认识。随着基因工程技术的发展,研究微生物化脱硫的单找到细菌,生物化脱硫絮凝剂的制备方法和微生物化脱硫催化剂的筛选微生物和嗜硫提升生物化脱硫分子遗传学的发展具有高脱硫活性的代谢机制的应用研究。此外,脱硫菌抵菌能力和脱硫能力的提高是一个研究方向。生物工程技术的发展将会转变诸多制约石油生物化脱硫研究工作的瓶颈。
Strengthen the research and understanding of the regularity and mechanism of microbial desulfurization process. With the development of genetic engineering technology, research on single bacteria of microbial desulfurization, preparation method of biological desulfurization flocculant and screening of microbial desulfurization catalyst, development of molecular genetics of microbial desulfurization and thiophilic enhancement, and Application Research on metabolic mechanism with high desulfurization activity. In addition, it is a research direction to improve the resistance and desulfurization ability of desulfurization bacteria. The development of bioengineering technology will change many bottlenecks that restrict the research of petroleum biological desulfurization.
进一步探索的措施和工艺的脱硫,注意解决大规模培养、回收、循环脱硫应变问题。由于在浮选操作中,须要有高浓度的细菌,可以有脱硫成果显明,因此探索在表面改性的工业生产,分选过程所需的细菌含量高。
Further explore the measures and process of desulfurization, pay attention to solve the problem of large-scale cultivation, recovery, circulating desulfurization. Because of the need for high concentration of bacteria in flotation operation, the desulfurization results can be obvious. Therefore, in the industrial production of surface modification, the bacterial content required in the separation process is high.
如果能在这些方面继续改良该技术,生物脱硫的应用将具有相当广阔的前景。
If we can continue to improve the technology in these aspects, the application of biological desulfurization will have a broad prospect.
