Catalytic Hydrogenation Using KCl-ZnCl2, Molten Salt Mixtures as a Catalyst

Details

• Personal Author:
  Berg L ; Malsam JS
• Description:
  KCl is incorporated with molten ZnCl2 in a coal or coal extract hydrocracking zone so that any reaction products and unreacted feedstock entrained in the catalyst can be separated from the spent catalyst in a simple gravity separation vessel the incorporation of KCl with the molten ZnCl2 in a mole ratio of 1:1 allows the lighter entrained hydrocarbon phase to readily separate out from the heavier spent molten salt phase so as to form two adjacent layers. To realize at least an 80 pct conversion of the feed stock, the operating temperature is approximately 400 deg. C at a pressure of 2,500 psig. During catalyst regeneration, the spent molten salt and entrained hydrocarbon phase from the hydrocracking zone are conveyed to a gravity settling zone to allow the heavier molten salt phase to settle out.
