Abstract
1495997 Desulphurizing char OCCIDENTAL PETROLEUM CORP 14 March 1975 [18 April 1974] 10846/75 Heading C1A Char, e.g. from coal, is desulphurized by washing it with an acid to react with and leach out inorganic compounds, and then treating the acidwashed char with a gas comprising molecular H 2 . The acid may be an aqueous mineral acid, at least 0À05 m., present in an amount of at least 2 parts of acid per part of char, and washing may be effected by agitating the char in an acid bath in air or under N 2 . The filtered char may be hydrogenated at 15-125 p.s.i.a. (1À05-8À79 kg./cm.<SP>2</SP>) at 1100-1800‹ F. (595-980‹ C.) for 1-120 minutes. The treating gas may be a H 2 /N 2 mixture which may contain 3-5% S-containing gases, e.g. H 2 S.
