This paper intends to show a model of a monolithic reactor for the autothermal reforming process (ATR), a process that uses hydrocarbons to produce H2. The ATR chemical reactions take place on the surface of monolith channels coated with a catalyst.

The isothermal ATR reactor is modeled using 42 catalytic surface chemical reactions that involve 13 solid species and 7 gas species. To solve the model, two numerical techniques with COMSOL are compared: the Surface Model using weak form equations (SM) and a standard thin Volume Model (VM).

This paper shows that the surface modeling (SM) is the better way to calculate the monolith catalytic reactions.
