Abstract
A process for the direct catalytic oxidation of methane to methanol comprises chromium chemically bound to the oxygen of a metal oxide catalytic support surface. The support may comprise silica, alumina, magnesia, titania, or zirconia.
Claims22
A method for the direct conversion of light alkanes to alcohols comprising contacting said light alkanes with an oxidant in the presence of catalyst comprising a surface oxide chromate in which chromium is chemically bound to oxygen of a metal oxide support surface.
A method for the direct conversion of light alkanes to alcohols comprising contacting said light alkanes with an oxidant in the presence of catalyst comprising a surface oxide chromate in which chromium is chemically bound to a zeolite, wherein said catalyst comprises the structure:
- ##STR4## wherein valence n is (VI), (IV), or (II) and y is 2, 1, or 0, respectively;
- and wherein X is zeolite.
