ABSTRACT:
A catalyst for adiabatically prereforming a feedstock wherein the catalyst comprises 1 to 20 wt. % nickel and 0.4 to 5 wt. % potassium on a calcium aluminate support. The overall catalyst porosity is greater than 40% with greater than 70% of the overall catalyst porosity contributed by pores having pore diameters of at least 500 Å, and having a median pore diameter greater than 2600 Å, and having a nitrogen BET area less than 6.5 m2/g.
