A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

To obtain deuterium in a gas state from a mixed gas of hydrogen and deuterium at a low cost.

A first electrode 11 is an electrode made of a metal allowing hydrogen (H component and D component) to permeate therethrough (hydrogen permeable metal), and the hydrogen permeable metal is Pd, for example. H ions and D ions having permeated through the first electrode 11 flow to the side of a second electrode 12 in a proton conduction layer 20. When the first electrode 11 is used as an anode and the second electrode 12 as a cathode, H ions and D ions flow in the proton conduction layer 20 from the left to the right in the drawing. In that case, hydrogen component in an input gas is more likely to flow into an atmosphere on the cathode side than deuterium component, and an H/D composition ratio accordingly becomes higher in a product gas than in the input gas. In an exhaust gas extracted after H and D components in the input gas are thus consumed, D component has been enriched.
