The stages of the process are shown in Fig. is slurried with hydrogenated recycle oil. The coaloil slurry is passed via a preheater to a simple reactor at 410 °C together with high pressure hydrogen (150 bar).
WhatsApp: +86 18203695377SYNTHETIC FUELSSynthetic fuels are usually thought of as liquid fuel substitutes for gasoline and diesel fuel made from petroleum sources. In broad context, the source of these synthetics can be any feedstock containing the combustible elements carbon or hydrogen. These include coal, oil shale, peat, biomass, tar sands, and natural gas.
