Catalysts for upgrading coal-derived liquids
Work continues on assessment of catalysts for S and N removal from coal liquids. A 150-h activity test was performed on Nalco 474 Sphericat catalyst using an FMC oil at 700/sup 0/F (371/sup 0/C), 1500 psig and 3 h space time. The resultant S removal was 94 percent with no signs of activity loss over the 150 hours. Denitrogenation activity showed a marked decay with an initial removal of 60 percent and a final value of 40 percent. Four other experimental runs were conducted using catalysts made from Ketjen support material and processing raw anthracene oil. These results are not yet available. Nearly all equipment items have been received for construction of the catalyst test unit and a data acquisition system has been ordered. Estimated construction is about 30 percent completed. The field ionization source for the CEC 21-110B double focusing mass spectrometer is now routinely operational. Its performance was assessed in part using known samples of compounds which are structurally related to those in coal liquids. Approaches to the semiquantitative analysis of coal type mixtures have been explored using the known samples. The techniques used were gas chromatography and field ionization and low-voltage electron-impact ion abundances. The consequences of sensitivity data on the analytical results have been considered. Although including sensitivity corrections enhances the accuracy of the analyses,reasonable sample composition estimates can be obtained without using the corrections.
