Method For The Regeneration Of Spent Molten Zinc Chloride

View page
US Patent:
42579147, Mar 24, 1981
Filed:
Dec 10, 1979
Appl. No.:
6/102164
Inventors:
Clyde W. Zielke - McMurray PA
William A. Rosenhoover - Pittsburgh PA
Assignee:
Conoco, Inc. - Stamford CT
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
B01J 2732
B01J 3512
C10G 106
C01B 900
US Classification:
252415
Abstract:
In a process for regenerating spent molten zinc chloride which has been used in the hydrocracking of coal or ash-containing polynuclear aromatic hydrocarbonaceous materials derived therefrom and which contains zinc chloride, zinc oxide, zinc oxide complexes and ash-containing carbonaceous residue, by incinerating the spent molten zinc chloride to vaporize the zinc chloride for subsequent condensation to produce a purified molten zinc chloride: an improvement comprising the use of clay in the incineration zone to suppress the vaporization of metals other than zinc. Optionally water is used in conjunction with the clay to further suppress the vaporization of metals other than zinc.

US Patent:
44241119, Jan 3, 1984
Filed:
Jun 1, 1982
Appl. No.:
6/383916
Inventors:
Clyde W. Zielke - McMurray PA
William A. Rosenhoover - Pittsburgh PA
Assignee:
Conoco Inc. - Wilmington DE
International Classification:
C10G 106
C01B 900
B01J 2732
B01J 3512
US Classification:
208 10
Abstract:
A method of hydrocracking using a zinc catalyst in the hydrogenation step comprising providing a hydrocarbonaceous feed of coal or tar to a hydrogenation means, removing spent zinc and catalyst from said hydrogenation means to a regeneration means, heating said spent zinc catalyst in said regeneration means, providing hydrogen chloride to said regeneration means, said spent zinc catalyst comprising ZnS, whereby ZnCl. sub. 2 gas is formed, contacting at least a portion of said ZnCl. sub. 2 with steam to form ZnO, conveying said ZnO and ZnCL. sub. 2 to said hydrogenation means.
