Abstract
The invention is a ceramic membrane reactor for syngas production having a reaction chamber, an inlet in the reactor for natural gas intake, a plurality of oxygen permeating ceramic slabs inside the reaction chamber with each slab having a plurality of passages paralleling the gas flow for transporting air through the reaction chamber, a manifold affixed to one end of the reaction chamber for intake of air connected to the slabs, a second manifold affixed to the reactor for removing the oxygen depleted air, and an outlet in the reaction chamber for removing syngas.
Claims14
A ceramic membrane reactor for syngas production comprising:
- a reaction chamber;
- an inlet in the reaction chamber for natural gas intake;
- a plurality of oxygen permeating u-shaped ceramic membrane slabs inside the reaction chamber;
- each slab having a plurality of passages for transporting air through the reaction chamber;
- a first manifold affixed to the reaction chamber for intake of air connected to an entrance of the slab passages;
- a second manifold affixed to the reactor for removing the oxygen depleted air, the second manifold connected an exit of the slab passages;
- and
- an outlet in the reaction chamber for removing syngas.
A ceramic membrane reactor for syngas production comprising:
- a reaction chamber;
- an inlet in the reaction chamber for natural gas in a pressure range of approximately 14.7 to 1000 psi;
- a plurality of oxygen permeating u-shaped ceramic membrane slabs inside the reaction chamber;
- each slab having a plurality of passages for transporting air through the reaction chamber;
- a first manifold affixed to the reaction chamber for intake of atmospheric air connected to an entrance to the slab passages;
