Claims
- 1. A process for converting methane to higher hydrocarbons, comprising the steps of:
- providing a methane gas;
- providing a catalyst comprising a support material selected from the group consisting of oxides of silicon, zirconium and magnesium; a manganese catalytic agent supported on the support material; and an alkali metal promoter impregnated into the catalyst; wherein a surface atomic ratio of promoter to manganese is at least 5; and
- contacting the methane gas with the catalyst at effective methane conversion conditions.
- 2. A process according to claim 1, wherein the contacting step is carried out at a temperature of between about 600.degree. C. to 900.degree. C.
- 3. A process according to claim 1, wherein the step of providing the methane gas comprises providing a mixture of methane with oxygen wherein a ratio by volume of methane to oxygen is between about 2:1 to 10:1.
- 4. A process for dehydrogenating a hydrocarbon, comprising the steps of:
- providing a feedstock including oxygen and dehydrogenatable hydrocarbon;
- providing a catalyst comprising a support material selected from the group consisting of oxides of silicon, zirconium and magnesium; a manganese catalytic agent supported on the support material; and an alkali metal promoter impregnated into the catalyst; wherein a surface atomic ratio of promoter to manganese is at least 5; and
- contacting the feedstock with the catalyst at effective dehydrogenation conditions.
- 5. A process according to claim 4, wherein the contacting step is carried out at a temperature of between about 600.degree. C. to 900.degree. C.
