Fuel cell power plants may be required to use coal derived liquid fuels or heavy petroleum distillates as fuels. Among the fuel processor candidates, the adiabatic reformer is at the most advanced state of development. The objective of the present program is to establish a reactor model for the adiabatic reformer which will predict process stream compositions and include carbon formation processes. Four subordinate tasks were proposed to achieve the objective. These are: 1) to determine on selected catalysts rate expressions for catalytic reactions occurring in the entrance section of the adiabatic reformer; 2) to determine with microbalance experiments critical conditions for carbon formation on selected catalysts; 3) to establish a reactor model to predict process stream compositions in the adiabatic reformer using data from Task 1 for catalytic reactions and data from the literature for homogeneous gas phase reactions; and 4) to establish a model to predict carbon formation by combination of the model for process stream composition from Task 3 and data for carbon formation from Task 2. Progress is reported. (WHK)
