Abstract
The hydrogenation and methyl esterification of furoic acid over Pd/γ-Al2O3 catalysts was investigated in fixed bed micro-reactor by one-step method.Effects of the reaction temperature,pressure,gas flow rate of H2,liquid flow rate of furoic acid and methol were studied.Under the optimal reaction conditions of 0.5MPa pressure,at 150℃,H2 gas flow rate of 5000mL·h-1 and liquid flow rate of 5.0mL·h-1,the conversion of furoic acid,selectivity to methyl tetra-hydro-furan formiate and yield of methyl tetra-hydro-furan formiate can reach 99.0%,98.2% and 97.2%,respectively.Performance of the catalyst does not deteriorate after being used for 360h.This green technology has the characteristic of low reaction pressure,easy operation,high activity and selectivity and stability of the catalyst and facile separation of the catalyst from products.
