Process of producing methanol |
摘要 |
Prepn. of MeOH from synthesis gas (I) contg. H2 and C oxides by reaction on catalyst (II) contg. Cu at 20-120 bar and 200-350 degrees <6>C. is carried out in 2 synthesis reactors. The process comprises (a) passing (I) through reactor 1; (b) discharging a first prod. mixt. (P1) contg. MeOH vapour and cooling to condense MeOH; (c) passing the remaining gases into reactor 2; (d) discharging a second prod. mixt. (P2) contg. MeOH vapour and cooling to condense MeOH; and (e) passing at least pt. of the remaining gases from P1 and P2 into reactor 2. The novel features are that (I) is at 220-270 degrees C. on entering reactor 1, which is a shaft reactor contg. a bed of (II) and operates adiabatically and without (I) circulation; and reactor 2 has (II) in tubes cooled indirectly by boiling water. <IMAGE> |
