摘要: Abstract This paper reviews recent developments in syn-gas production processes used for partial methane oxidation with and/or without steam. In particular, we examined different process charts (fixed bed, fluidised membrane, etc.), kinds of catalysts (powders, foams, monoliths, etc.) and catalytically active phases (Ni, Pt, Rh, etc.). The explanation the various suggested technical solutions accounted reaction mechanism that may selectively lead to calibrated mixtures CO H2 or unwanted formation products total (CO2 H2O) pyrolysis (coke). Moreover, new classes allow use small reactors treat large amounts (monoliths) separate hydrogen situ from other (membrane). leads higher conversions selectivity than could have been expected thermodynamically. Although based on Rh are extremely expensive, they can be minimise H2O by maximising yield.
