Abstract
Disclosed is an apparatus for producing a hydrogen gas according to the present disclosure. The apparatus includes a desulfurizer, a plasma reactor, a separator, a first heat exchanger, a second heat exchanger, and a first adsorber, and circulates at least a portion of a first off gas to the plasma reactor again.
Claims5
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 a 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 heat exchanger configured to exchange heat between the desulfurized hydrocarbon containing gas and the low-purity hydrogen gas;
- a second heat exchanger configured to exchange heat between the hydrocarbon containing gas and the low-purity hydrogen gas that exchanged heat in the first heat exchanger;
- a first adsorber configured to separate the low-purity hydrogen gas that exchanged heat in the second heat exchanger into a first high-purity hydrogen gas and a first off gas, through adsorption;
- and
- a second adsorber configured to separate the first off gas to a second high-purity hydrogen gas and a second off gas through adsorption.
