  • Coal liquefaction Wikipedia

    Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals This process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products However, the most common process chain is "Coal to Liquid Fuels" (CTL) Historical background Coal liquefaction originally was developed at the beginning ofCoal is a common substrate for liquefaction in countries deprived of a firm distribution of petroleum such as Germany (during World War II) and South Africa (since the early 1970s) 200 According to Lumpkin, 201 direct liquefaction was established by I G Bergius in Germany in the 1930s, the research included the reacting of coal with H 2 at elevated pressures and temperaturesDevelopments in waste tyre thermochemical conversionPotential secondgeneration catalytic materials for the direct liquefaction of coal to boiler fuel are studied Both fundamental aspects and engineering constraints were considered in evaluating materials and assigning a priority for further study A synopsis of relevant background information, the nature of the study, and the evaluation of materials is presented along with a detailed analysisNew catalytic materials for the liquefaction of coal
