| Indirect coal liquefication is an important process when syngas(H2+CO)derived from coal are converted into liquid fuel and a wide variety of hydrocarbons. A new smectite-type of catalyst was prepared by co-precipitation of FeCl3•6H2O and Na2SiO3 (sodium silicate). Structural analysis by XRD,SEM and N2 adsorption-desorption indicated that this catalyst had a high specific surface area. The pretreated catalyst was introduced into the FT synthesis in a slurry bed reactor. The reaction was carried out at 543K and 0.5MPa,1.0NL/g-cat/h,H2/CO=2 for 6 hours, providing the liquid product at 87.99wt% yield. Analysis of the product showed that the selectivity of C5-C15 hydrocarbons achieved above 90%, which had broken the ASF distribution rule. |
