Study on the components of biodiesel fuel as additive to improve the lubrication performance of ultra low sulfur diesel fuel 生物柴油的成分对提高超低硫(ULS)柴油润滑性影响的研究
In this paper the technologic research of the ultra low sulfur steel based on the production of X70 / X80 pipe-line steel was discussed. 本文论述了以马钢X70、X80管线钢生产为平台的超低硫(ULS)钢的生产工艺研究。
Deactivation model of hydrotreating catalyst for ultra low sulfur diesel fuel production 柴油超深度加氢脱硫催化剂失活模型的建立
The production of ultra low sulfur diesel mainly depends on hydrodesulfurization and non-hydrodesulfurization technologies. 生产超低硫(ULS)柴油的技术主要有加氢脱硫(HDS)和非加氢脱硫两大方法。
By comparisons of steelmaking processes and the cost indexes, it is concluded that deep desulphurization in steel refining is necessary for making ultra low sulfur steel. 通过对比工艺流程和成本指标,指出在生产超低硫(ULS)钢时,钢水炉外精炼深脱硫的必要性。
