IMPROVEMENTS IN OR RELATING TO THE MANUFACTURE OF POWER GAS AND
THE RECOVERY OF HYDROCARBON OILS
Frederick W. Chamier, Harold J. Craig, and Julius F. L. Moeller, London, England
Oct. 21, 1918; application filed Dec. 21, 1916, Serial No. 18,335/16; 4 claims.
1. A process of the kind set forth employing distillation and combustion of
the fuel in two successive stages, in which part of the gases from the second
or gas generating stage are mixed with steam and reduced to a relatively low
temperature and are caused to act, at the reduced temperature of about
450 C. to 6500 C., upon the fuel in the first stage, for the purpose specified.Br. 120,546
PROCESS AND APPARATUS FOR THE PRODUCTION OF AMMONIA FROM
ATMOSPHERIC NITROGEN
General Chemical Co., New York, N.Y., a corporation of New York, assignees of
Fredrik Wexelsen De Jahn, New York, N.Y.
Jan. 15, 1920; application filed Feb. 28, 1918, Serial No. 3607/18; 6 claims.
1. A process for the production of ammonia from atmospheric nitrogen
consisting in introducing into an incandescent carbonaceous material, such
regulated quantities of steam and air as will produce a crude gas containing
approximately one volume of nitrogen to three volumes of gas composed of
hydrogen and carbon monoxide; removing dirt, sulphur and the like, from
said gas; admitting regulated quantities of steam with said gas and passing
the mixture over a catalyser at the required temperature without increasing
the pressure so as to oxidise the carbon monoxide into carbon dioxide and
to form hydrogen; applying a substantial pressure not exceeding 1,400 lbs.
at the maximum, to said gas mixture; removing carbon dioxide and sulphur
impurities by water scrubbing and carbon monoxide and further sulphur
impurities by means of caustic soda whilst maintaining said pressure; re-
moving oxygen and carbon monoxide by treating the gas with cuprous mate-
rial, such as cuprous ammonia carbonate; removing any traces of moisture,
and passing the gases through a catalysing agent, to combine the nitrogen
and hydrogen to form ammonia without raising the pressure above 1,400 lbs.2 j
