PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS ABSTRACT OF THE DISCLOSURE A process starting from a hydrocarbon feedstock, and aiming to produce a synthesis gas suitable either for methanol synthesis or for other applications requiring a low H2/CO ratio. In this process, the feedstock is first desul- furized if necessary, then divided into two fractions; a first fraction undergoes a primary steam reforming at high pressure and moderate temperature; the gas effluent from said primary steam reforming, as well as the second fraction of the feedstock, subsequently undergo jointly a secondary reforming by reaction with an oxygen contai- ning gas in a reactor operating under essentially adia- batic conditions. The synthesis gas obtained as effluent from said secondary reforming, has a composition adjustable at will in a wide range, and therefore can be made as close as necessary to the stoechiometric composition required for methanol synthesis, or has a low H2/CO ratio for other applications, and this synthesis gas is available at high pressure, and can therefore feed directly, without com- pression, the synthesis loops downstream. The process of the present invention is particu- larly suitable for methanol production on a very large scale. - 1 -
