Abstract
The present invention describes improved methods of introducing promoters to catalysts. This invention provides a method for dispersal of a promoter onto a solid surface. A catalyst material and a deliquescent material can together be contacted with a gas phase comprising a solvent under conditions effective for deliquescence whereby the promoter is dispersed onto the solid surface. This invention combines practical benefits of dry-mixing with the enhanced dispersion that can be realized by solvent-based methods.
Claims22
A method for dispersal of a promoter onto a solid surface, said method comprising:
- (i) providing a catalyst material comprising a solid surface that is at least partially hydrophilic;
- (ii) providing a deliquescent material comprising, in free or combined form, a promoter;
- (iii) mixing said catalyst material and said deliquescent material, thereby creating a mixture;
- and
- (iv) contacting said mixture with a gas phase comprising a solvent, under conditions effective for deliquescence, whereby said promoter is dispersed onto said solid surface.
A method for dispersal of a promoter onto a solid surface, said method comprising:
- (i) providing a catalyst material comprising a solid surface that is at least partially hydrophilic;
- (ii) providing a deliquescent material comprising, in free or combined form, a promoter;
- (iii) mixing said catalyst material and said deliquescent material, thereby creating a mixture;
- and
- (iv) contacting said mixture with a gas phase comprising a solvent, under conditions effective for deliquescence and at a temperature such that said solvent is condensable, whereby said promoter is dispersed onto said solid surface.
A method for producing at least one C1-C4 alcohol, said method comprising
- (i) providing a catalyst material comprising a solid surface that is at least partially hydrophilic;
- (ii) providing a deliquescent material comprising, in free or combined form, a promoter;
- (iii) mixing said catalyst material and said deliquescent material, thereby creating a mixture;
- (iv) contacting said mixture with a gas phase comprising a solvent, under conditions effective for deliquescence, whereby said promoter is dispersed onto said solid surface, thereby generating a promoted catalyst;
- and
- (v) contacting said promoted catalyst with syngas to produce at least one C1-C4 alcohol.
