The feasibility of utilizing an expanded bed reactor (LC-Fining Process) for upgrading coal extracts has been expanded to include not only SRC-I feedstock, but also non-deashed/deashed short contact time (SCT) coal extract feedstocks. Another objective of this work was to extend the range of operating variables in the LC-Finer to include operation at higher space velocity and higher total reactor pressure. A given 850/sup 0/F+ conversion could be attained at various combinations of the operating variables. It was then shown that this 850/sup 0/F+ conversion became a correlating parameter for gas and liquid product distribution. The expanded range of the operating variables correlated well with data which was previously accumulated at a constant set of operating conditions. Non-deashed SCT PDU runs in the LC-Finer show a different product distribution than PDU runs made with SRC-I. However, deashed SCT showed a similar product distribution at milder operating conditons. SCT PDU runs in the LC-Finer exhibit a higher livel of denitrogenation in the total liquid product.
