摘要：

ChemCad 6.5.6 simulation package has been used to study the effect of light hydrocarbons (n-C-5 to n-C-10) on the effective diffusivity of reactants in solid catalyst during the conversion of waste vegetable oils (WVO) into biodiesels in presence of methanol. The WVO was simulated as a mixture of triolein and oleic acid. The results suggest that light hydrocarbons significantly lower the reaction medium viscosity and consequently improve reactants diffusivity in the catalyst. Comparisons based on the same hydrocarbon-to-WVO ratio suggest that short-chain hydrocarbons are more effective in lowering the reaction medium viscosity than hydrocarbons with long carbon chain.
