<p>1,233,473. Hydrogen; synthesis gas. TEXACO DEVELOPMENT CORP. 6 May, 1969 [29 May, 1968], No. 22926/69. Heading C1A. [Also in Division C5] Hydrogen, which may be mixed with nitrogen to make an ammonia synthesis gas, is made by a partial combustion process using as feedstock a hydrocarbon liquid mixed with enough water to provide all the steam for the reaction, the temperature of which is autogenously maintained at 1800‹ to 3200‹ F. (c. 980‹ to 1760‹ C), by reaction with a gas comprising at least 95 vol. per cent oxygen. Both components may be in the form of slurries with carbon, and the feedstock and the oxygen may be preheated, e.g. to 250‹ F. An illustrated embodiment, see Figure (not shown) shows carbon recovery, including recycling, gas washing stages, a CO-conversion stage, and CO 2 - removal stage. Liquid nitrogen may be used to wash the hydrogen, so providing an ammonia synthesis gas.</p> |
