3323  SELLERS, F. B.  (Texaco Development Corp.).  Catalytic Synthesis of Hydrocarbons.  United States Patent 2,464,532, Mar. 15, 1949; appl. filed Sept. 10, 1948, Serial No. 48,740; 10 claims (Cl. 260-449.6).  Chem. Abs., vol. 43, 1949, p. 4448.

This patent is related to United States Patent 2,464,501 (abs. 836), which uses the typically high temperature thermal energy of a synthesis gas generator effluent to convert hydrocarbon synthesis products.  The present invention goes a step further in that it concurrently effects removal of C deposits laid down during the conversion or cracking step in such a manner as to supplement the synthesis gas with substantial additional quantities of H₂ and CO.  The thermophore  is raised in the heating zone to a temperature materially above the conversion range and, after withdrawal from contact with the hot effluent  gas stream the C-coated particles are subjected to H₂O vapor and CO₂.  At temperature > 1,200° F. and within the maximum upper limit of temperature to which the thermophore may be raised by the high temperature generator effluent(2,000°-3,000°), the H₂O vapor and/or CO₂ decomposes and removes the C deposits with substantial formation of synthesis gas. 6 United States patents cited.
