Abstract
A process is disclosed for the partial oxidation of a hydrocarbon feedstock to produce a hydrogen and carbon monoxide synthesis gas employing a temperature of 800.degree. C. or more, one or more inorganic oxide or oxides and space velocities of 500,000 Nl/kg/hr or higher. The catalyst is present on a foamed support which has been present with an impregnating medium comprising one or more inorganic oxide or oxides having a viscosity of greater than 1 cps at 20.degree. C.
Claims18
In a process for the catalytic partial oxidation of a hydrocarbon feedstock to produce a synthesis gas comprising hydrogen and carbon monoxide which employs temperatures greater than or equal to 800.degree. C., a catalyst comprising a foamed support for one or more inorganic oxide or oxides catalysts and space velocities greater than or equal to 500,000 Nl/gk 1 hr, the improvement which comprises impregnation of said foamed catalyst support with an impregnating medium comprising one or more inorganic oxide or oxides and having a viscosity of greater than 1 cps at 20.degree. C. which is treated by means of ultrasound to minimize the content of inorganic precursor particles having a size greater than 300 nm and;
- whereafter the support is dried before use in the catalytic partial oxidation process.
The process according to claim I wherein the viscosity of the impregnating medium ranges from 7 to 50 cps at 20.degree. C.
The process according to claim i wherein pores of the ceramic foam are substantially filled with impregnating medium prior to drying and said drying is performed without substantial draining of excess impregnating medium from the ceramic foam.
