Abstract
Disclosed is an apparatus for producing a hydrogen gas according to the present disclosure includes a desulfurizer, a plasma reactor, a first adsorber, and a heat exchanger. The disclosed apparatus does not require additional purification of hydrogen and has excellent energy efficiency by utilizing wasted heat of the produced hydrogen.
Claims6
An apparatus for producing a hydrogen gas, the apparatus comprising:
- a desulfurizer configured to desulfurize a hydrocarbon containing gas;
- a plasma reactor configured to generate the hydrogen containing gas from the desulfurized hydrocarbon containing gas through plasma based pyrolysis;
- a separator configured to separate a low-purity hydrogen gas from the hydrogen containing gas;
- a first adsorber configured to separate the low-purity hydrogen gas that is separated by the separator to a first high-purity hydrogen gas and a first off gas, through adsorption;
- and
- a heat exchanger configured to exchange heat between at least a portion of the first off gas discharged from the first adsorber and the low-purity hydrogen gas separated by the separator,
- wherein the first off gas discharged from the heat exchanger is introduced into the plasma reactor.
