Fundamental reaction pathways during coprocessing. Thirteenth quarterly technical progress report and milestone status report
We have been carrying out an investigation that is studying the role of dihydrogen in the coprocessing reaction. The initial research on this part of the project has been reported. In that contribution, Illinois No. 6 coal or Wyodak coal and Lloydminster resid or Hondo resid was mixed with a molybdenum based UOP proprietary catalyst was carried out under a 3000 psi dideuterium atmosphere at 420{degrees}C with a heat up time of 120 minutes and a residence time of 120 minutes. Quantitative 1H and 2H NMR analyses yielded similar results for the four combinations of coals and resids. Specifically, the degree of deuteration, (D/H+D), of the coprocessed products approached 0.25, the value that was expected for complete equilibration of the isotopes among the available positions in the oil, resin, and asphaltene. These results established the ultimate unselective character of the severe coprocessing reaction. However, we sought information on the limiting processes. Accordingly, additional coprocessing reactions with Illinois No. 6 coal and Lloydminster resid have been carried out under less severe conditions to investigate how the dideuterium utilization in the reaction products is affected by changes in the temperature and pressure.
