ABSTRACT:

A comprehensive program has been developed to predict the performance of coal liquefaction preheaters and reactors. The simulator is interactive and allows the user to input any linear kinetic network by specifying the reaction paths. The user must also specify the operating conditions and the physical dimensions of the units. The simulator then provides detailed information on the performance of each unit, the characteristics of each flow stream, and an overall summary of the products leaving each unit. A first draft report on the Fischer-Tropsch (F-T) synthesis has been prepared. The introductory section deals with the history of the F-T reaction and early German work on F-T catalysts. The next section deals with the fundamentals of the conversion of synthesis gas to fuels and chemicals. The next section deals with SASOL technology and some of the developmental work that is ongoing at SASOL, in particular, work on slurry reactors, processes at SASOL for upgrading the primary products of the F-T synthesis to gasoline and diesel fuels and improvements in downstream operation. The final section deals with new catalysts that have been tested in the laboratory and on pilot plant scale for narrowing the product distribution in synthesis gas conversion. Reports on Viscosity of Coal Liquids and Slurries and Thermal Conductivity of Coal Liquids and Slurries have been prepared. Research has been initiated on two important areas of coal liquefaction, Heat of Reaction of Direct Coal Liquefaction and Dimensionless Numbers for Coal Liquids. Work on dimensionless groups of coal liquids has been primarily concentrated on the Prandtl number of various coal liquid fractions. 3 references. (ERA citation 09:025211)
