Research and development as an advanced process for conversion of coal to synthetic gasoline and other distillate motor fuels. Quarterly report, September--November 1977. [Tracer studies]
The overall objective of this project is to perform the research and development work necessary for the creation of an advanced process for conversion of coal to synthetic gasoline and other distillate motor fuels. This is to be accomplished by developing a pyrolytic coking process for the delayed coking of various coal/petroleum resid slurries to a coker distillate for Fluid Catalytic Cracking to a high octane gasoline blending feedstock. The coke produced should be suitable for use as a power plant fuel, neat, or when blended. This coke should also be suitable for gasification to hydrogen to meet refinery hydrogen requirements. The use of coal in this mode will divert petroleum resid to Fluid Catalytic Crackers for enhanced production of gasoline and fuel. The final exploratory coking runs were continuously charged through a preheater to a one-gallon autoclave at 35 psig. The runs made with Kentucky No. 9 bituminous coal: West Texas resid slurries showed that rapid heating during continuous charging restored the 2.0 weight percent synergistic reduction in coke yield that was lost by slow heating during the incrementally charged runs. Synergism was not retained in runs made with pre-dried Big Horn sub-bituminous coal due either to predrying and/or pre-oxidizing the coal. Final results of laboratory coking experiments done with tagged samples indicate that no C--C transfer occurs during coking and no hydroaromatics are retained in the coke or heavy asphaltene fraction. A high level of hydrogen transfer occurs during coking and appears to be general H--H scrambling, possibly promoted by the metal reactor or coal mineral matter functioning as a catalyst.
