摘要： A continuous process for simultaneously producing a stream of cleaned purified synthesis gas having a mole ratio H.sub.2 /CO in the range of about 2 to 12, and a separate stream of CO-rich gas. In one embodiment of the process, cleaned and purified methanol synthesis gas and substantially pur carbon monoxide are produced. Methanol may be synthesized and optionally catalytically reacted with the substantially pure carbon monoxide to produce acetic acid. In the subject process, the effluent gas stream directly from a free-flow unpacked noncatalytic partial-oxidation synthesis gas generator is split into two streams which are simultaneously processed in two separate trains. In the first train, one of the split streams is cooled by indirect heat exchange in a gas cooler and then further processed to produce a stream of cleaned and purified synthesis gas, a H.sub.2 -rich gas stream, and the product stream of CO-rich gas and preferably substantially pure CO. Simultaneously, the second split stream in the second train is cooled by direct quenching in water in a quench drum, cleaned, subjected to catalytic water-gas-shift reaction, and purified to produce a second H.sub.2 -rich gas stream. The product stream of cleaned and purified synthesis gas having a mole ratio H.sub.2 /CO in the range of about 2 to 12 is then produced by mixing together at least a portion of the cleaned and purified synthesis gas stream from the first train with 0 to 100 volume % of the H.sub.2 -rich gas stream from the first train and at least a portion of the H.sub.2 -rich gas stream from the second train.
