鉴于世界轻质原油不足,今后将不得不增加煤炭、重质原油、页岩油等重质矿物燃料在能源构成中的比重。然而这些重质矿物燃料含硫含氮量高,直接作为燃料使用会造成因氧化硫和氧化氮(SOx,NOx)引起的大气污染。因此,现在的迫切问题是建立起一套技术,将重质矿物燃料同时进行加氢脱氮和加氢脱硫,并以尽可能少的氢耗生产出清净的液体燃料油。 In view of the shortage of light crude oil in the world, the proportion of heavy fossil fuels such as coal, heavy crude oil and shale oil will have to be increased in the energy mix in the future. However, these heavy fossil fuels have high sulfur and nitrogen contents and can be directly used as a fuel to cause air pollution due to sulfur oxides and nitrogen oxides (SOx, NOx). Therefore, the pressing issue now is to establish a technology that will simultaneously carry heavy hydro-denitrification and hydrodesulfurization of heavy fossil fuels and produce clean liquid fuel oil with as little hydrogen consumption as possible.
