Title: Syngas production utilizing an oxygen transport membrane
Inventor: GOTTZMANN CHRISTIAN FRIEDRICH
IPC: C01B3/52
Filed: 2002-04-09
Abstract: A method of producing a crude syngas product stream (46) or a syngas product stream (64) by further processing of the crude syngas product stream (46). Both the crude (46) and syngas product stream (64) comprise carbon monoxide and hydrogen. The crude syngas product stream (46) additionally comprises carbon dioxide and moisture. In accordance with the method, methane in a fee d stream is converted into the hydrogen and carbon monoxide in at least two stages (41, 42; 41, 42'), thereby to form a crude syngas stream (46). An initial stage has an oxygen transport membrane reactor (14) having a catalys t (40) to promote carbon dioxide or steam methane reforming. Since, the conversion is shared between two stages (41, 42; 41, 42'), the oxygen transport membrane reactor (14) can be operated at a sufficiently low temperature to avoid ceramic membrane deterioration due to creep effect. The subsequent stage (42; 42') can be operated at a higher temperature with more favorable equilibrium conditions to complete the conversion of the methane.< /SDOAB>
