Abstract
An improved process for manufacture of a purified gas containing hydrogen and carbon monoxide is described wherein a fuel is partially combusted in a reactor to produce a crude gas product containing soot, ash and contaminating gases such as HCN, H.sub.2 S and COS, the crude gas product is subsequently cooled in a waste heat boiler and the cooled gas is washed in a scrubber to remove the entrained soot particles. In this improved process, removal of soot, ash and gaseous contaminants from the cooled crude gas product is facilitated by washing the cooled gas in a scrubber with an aqueous salt solution containing at least 10% by weight of an alkaline water-soluble salt, which salt solution is subsequently regenerated by removal of absorbed gases and suspended solids (soot and ash) and recycled to the scrubber.
