PCT No. PCT/SU87/00112 Sec. 371 Date Jun. 7, 1988 Sec. 102(e) Date Jun. 7, 1988 PCT Filed Oct. 14, 1987 PCT Pub. No. WO88/02744 PCT Pub. Date Apr. 21, 1988.A method of preparing methanol consists in that a synthesis-gas containing carbon oxides and hyddrogen is passed through a fixed bed of a copper-containing catalyst under pressure of 3.0-15.0 MPa at a temperature of from 150 DEG to 300 DEG C. The catalyst is divided into two parts either in an equal proportion or in a smaller/greater ratio equal to 0.5-1. The gaseous mixture obtained after passing the first part of the catalyst bed is stirred prior to the supply thereof to the second part of the catalyst bed. As a result, the reaction mixture is formed containing the aim product. Each subsequent direction of passing the synthesis-gas through the catalyst bed and that of removing the reaction mixture are changed to opposite with respect to the previous direction. |
