Abstract: Method for producing synthesis gas for methanol production. The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a hydrocarbon containing feed, particularly natural gas, is subjected to catalytic partial oxidation (CPO), followed by the water gas shift (WGS) reaction of a part of the reformed feed. At least part of the shifted feed is then subjected to hydrogen purification, preferably by pressure swing adsorption (PSA) to obtain pure hydrogen, which hydrogen is subsequently combined with the remaining parts of the feeds to yield synthesis gas particularly suitable for methanol synthesis. The recombined stream preferably has an R ratio, being the molar ratio (H2-CO2)/(CO+CO2), in the range 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol.
