Stu y on m ethanol synthesis has been carrie out in the hot m o el expermi ental apparatus, an the effects of these factors such as slurry recirculation flow rate, space velocity, concentration of catalyst, the num ber of nozzle on the m ethanol synthesis has been investigate in the present stu y. The results show that the outlet pro uct concentration an spacetmi e y iel increase w ith slurry recirculation flow rate, concentration of catalyst an the number of nozzle. H igh space velocity of syngas enhance the spacetmi e yiel of catalyst, but ecrease the outlet pro uct concentration.
