Abstract

Abstract Process for production of synthesis gas in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complate combustion are introduced into a bed of particulate material. The bed comprises material which is catalytically active for partial oxidation and/or steam reforming reactions. The upward flow rate of the hydrocarbon/oxygen containing gas steam is sufficiently large to cause a spouting action of the bed material. The hydrocarbon and oxygen react together and the products of the reaction are withdrawn.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 97 words
A process for the production of synthesis gas in which (a) a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichmetric ratio for complete combustion are introduced into a bed of particulate material, the bed comprising material which is catalytically active for partial oxidation and/or steam reforming reactions, (b) the upward flow rate of the hydrocarbon/oxygen containing gas stream being sufficiently large to cause a spouting action of the bed material, (c) the hydrocarbon and oxygen reacting together and (d) the products of the reaction being withdrawn.
Claim 2
Dependent Claim 97 words
A process for the production of synthesis gas in which (a) a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichmetric ratio for complete combustion are introduced into a bed of particulate material, the bed comprising material which is catalytically active for partial oxidation and/or steam reforming reactions, (b) the upward flow rate of the hydrocarbon/oxygen containing gas stream being sufficiently large to cause a spouting action of the bed material, (c) the hydrocarbon and oxygen reacting together and (d) the products of the reaction being withdrawn.
Claim 3
Dependent Claim 33 words
A process according to claim 1 in which the catalytically active material comprises a metal or metals of Group VIII of the Periodic Table of the Elements deposited on a porous refractory support.
Claim 4
Dependent Claim 16 words
A process according to claim in which the metal or metals is nickel, iron of platinum.
Claim 5
Dependent Claim 24 words
A process.according to claim 2 in which the catalytically active material comprises a mixture of Group VIII metals deposited on a porous refractory support.
Claim 6
Dependent Claim 17 words
