A catalytic partial oxidation or secondary reforming process wherein a flame is established at a burner upstream of the catalyst is started-up by catalytic combustion of a suitable combustible material to produce a hot gas stream and directly, or indirectly, using the heat from the gas stream to heat the reactants fed to the burner to the autoignition temperature. After a flame has been established at the burner, production of the hot gas stream by combustion of the combustible material is discontinued.

A method of start-up of a continuous process for the production of a gas stream containing hydrogen and carbon oxides wherein reactant streams including (a) a stream containing a gaseous hydrocarbon, or hydrocarbon derivative, feedstock, and (b) a stream containing an oxidant gas containing free oxygen, are separately fed, at elevated pressure, to a burner where partial combustion takes place, and the combustion products are fed over a catalyst to bring the combustion products towards equilibrium, comprising (i) producing a hot gas stream by effecting at least partial combustion of a stream of a gaseous combustible material and an oxidant gas containing free oxygen, said hot gas stream being produced at least initially by catalytic combustion by passing said combustible material and said oxidant gas over a combustion catalyst; (ii) heating at least one of the reactant streams, directly or indirectly, with said hot gas stream to a temperature above the autoignition temperature of said reactants and feeding the reactants streams to said burner, whereby autoignition of said reactant streams is effected to produce a flame at said burner and self-sustaining combustion of said feedstock is established; and thereafter (iii) discontinuing the production of said hot gas stream while continuing feed of said reactant streams to the burner.
