The Orthogonal Test of the Methanol Synthesis from Biomass

In order to research reaction conditions to change the agricultural residues into the fuel methanol, pyrolysis test of comstalk biomass fuel gas by the thermochemical method, and the optimum tests which the synthesis gas produced in comstalk fuel gas were performed. When the kinds, particle size, the ways of stuffing and activation of catalyst, and syngas composition keep constant, the orthogonal test of methanol synthesis reaction factors (such as pressure and temperature of synthesis reaction, and entrance flow of syngas) were carried out in a tubular-flow integral and isothermal reactor. The influence order of three representative factors in the time space yield of CH3OH is determined through orthogonal test. The order is arranged like this, entrance flow of syngas, reaction pressure and reaction temperature. The optimum combination of three factors is as follows, temperature 250°C, pressure 4 MPa, and entrance flow of syngas (standard condition) 0.6mol·h⁻¹.
