Activation of methane by transition metals-substituted aluminophosphate molecular sieves
Patent

OSTI ID:6834662
This patent describes a process for converting methane (CH[sub 4]) to C[sub 2+] hydrocarbons using a molecular sieve having a template. It comprises: calcining a transition metal-substituted aluminophosphate molecular sieve at 500-550[degrees]C in flowing air to remove the template or any coke that is present and to oxidize the transition metal to the trivalent state, passing CH[sub 4] over the aluminophosphate molecular sieve at 400 to 550[degrees]C, whereby the transition metal is reduced to a divalent state and the CH[sub 4] is converted to C[sub 2+] hydrocarbons.
