Claim:
1. A method for producing a product composition comprising methanol, comprising the steps of (i) producing a first stream of synthesis gas having a module greater than 2.0, in a steam methane reformer (SMR) or in a steam methane reformer followed by an autothermal reformer, by reforming a first hydrocarbon feed stream and steam in the presence of a catalyst; (ii) producing a second stream of synthesis gas having a module less than that of the first stream of synthesis gas, by partial oxidation or autothermal reforming of a second hydrocarbon feed stream; (iii) combining the first stream of synthesis gas and the second stream of synthesis gas to form a combined synthesis gas stream; and (iv) synthesizing the combined synthesis gas product stream in a methanol synthesis reactor into a product composition comprising methanol; and further comprising the step of recycling a portion of the excess hydrogen and methane slip formed during synthesis of the product composition comprising methanol to the steam methane reformer.
