摘要: A process for enhancing H2 or CO production in a partial oxidation reaction by feeding H2O or CO2 with the feed hydrocarbon and oxygen over a transition metal monolith catalyst such as unsupported Ni monolith or alternatively contacting the hydrocarbon/oxygen first with a noble metal then with a transition metal with the H2O or CO2 being added before or after the noble metal catalyst. The addition of H2O suppresses CO and enhances H2 production and the addition of CO2 suppresses H2 and enhances CO production. Little steam or CO2 reforming occurs with the addition of up to 32% H2O or CO2 respectively. Thus, the ratio of H2:CO which is about 2 in a conventional partial oxidation is manipulated by the addition of either water or CO2 to the partial oxidation.

摘要: A high heat flux catalytic radiant burner of the present invention includes a housing with an inlet and an outlet end. A catalyst layer which has a coating disposed on a support is positioned between the two ends. The catalyst layer has a total specific surface area of 0.1 to 10 m.sup.2 /g. The support has a specific surface area of 1 m.sup.2 /g or less. The coating is a thin film of a nobel metal. A mixture of air and gas enters the housing though the inlet end and enters the catalyst layer where the gas is oxidized and releases heat such that the burner maintains operational firing rates of approximately 40 to 413 kBTU/hr ft.sup.2 and produces extremely low emissions.
