摘要：

The rate of furfural decarbonylation was investigated in the presence of a charcoal supported palladium catalyst using potassium carbonate as accelerator in the liquid phase between 150 and 160 degree C. Reaction speed varied with the quantity of catalyst and increased exponentially with temperature. Activation energy under the experimental conditions was 310 kJ/mol. Reactions by-products were mainly of high molecular weight, resulting from various dimerization reactions involving furan and/or 2-methyl furan. These products covered the surface of the catalyst and blocked active sites, resulting in deactivation.
