As the demand and production of biodiesel increase exponentially, the utilization of the biodiesel byproducts will be of commercial significance. The conversion of biodiesel byproducts to synthesis gas and then to methanol represents an important niche for byproduct processing that could reduce the dependence of biodiesel producers on natural gas, thus reducing fossil fuel needs.

520 $a The autothermal reforming of glycerol into syngas was firstly studied using the BASF dual layer monolith catalyst, which the catalytic partial oxidation catalyst layer is in direct contact with the steam reforming catalyst layer next to the monolith wall. The optimum operating conditions to produce high yields of H2, CO and H2/CO molar ratio of &sim;2 with minimal coke formation were determined. The Aspen simulation software package was used to determine the equilibrium product composition for various reaction conditions. A comparison between equilibrium and experimental data was made, and the agreement was generally good indicating that close-to-equilibrium conditions were attained for the selected reaction conditions.
520 $a Kinetic study of autothermal reforming of glycerol was performed in a dual layer monolith catalyst to be used in the design of chemical reactors to optimize product (H2 and CO) yield and more efficiently adjust the H2/CO ratio. Kinetic experiments were carried out to measure the effects of the steam to carbon molar ratio, oxygen to carbon molar ratio, and temperature on the rate of reaction. Mass and heat transfer resistances were found to be negligible. Reaction rate expressions were based on proposed reaction mechanisms using the Langmuir-Hinshelwood approach. Non-linear regression was performed to obtain kinetic constants and activation energy. The later was found to be about 131 kJ/mol. Mechanistic considerations indicated that glycerol underwent non-dissociative adsorption and steam underwent dissociative adsorption. The modeling results were successfully validated with experimental data. The autothermal reforming of biodiesel byproducts into synthesis gas was experimentally studied at last. As high as 98% total gaseous carbon yield was obtained with near equilibrium concentrations of H2, CO, CO 2, and CH4. The optimum operating conditions to produce high yields of syngas with minimal coke formation were also determined. The Aspen simulation software package was used to calculate the equilibrium product composition for autothermal reforming of actual biodiesel byproducts on molecular basis. A comparison between equilibrium and experimental data was made, and the agreement was generally good indicating that close-to-equilibrium conditions were attained for the selected reaction conditions.
