Abstract
Official abstract text for this publication.
Disclosed is an acid-resistant alloy catalyst comprising nickel, one or more rare earth elements, stannum and aluminum. The acid-resistant alloy catalyst is low-cost and stable, and does not need a carrier, and can be stably used in continuous industrial production, thus achieving a low production cost.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite catalyst comprising (i) an acid-resistant alloy catalyst consisting essentially of, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin and 5-9 parts aluminium and (ii) a cocatalyst consisting of a soluble tungstic acid salt and/or an insoluble tungsten compound. 2. A composite catalyst comprising (i) an acid-resistant alloy catalyst consisting essentially of, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin, 5-9 parts aluminium and 1-90 parts tungsten and (ii) a cocatalyst consisting of a soluble tungstic acid salt and/or an insoluble tungsten compound. 3. A composite catalyst comprising (i) an acid-resistant alloy catalyst consisting essentially of, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin, 5-9 parts aluminium, 1-90 parts tungsten and 0.5-20 parts molybdenum and (ii) a cocatalyst consisting of a soluble tungstic acid salt and/or an insoluble tungsten compound. 4. A composite catalyst comprising (i) an acid-resistant alloy catalyst consisting essentially of, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin, 5-9 parts aluminium, 1-90 parts tungsten, 0.5-20 parts molybdenum, and 0.01-5 parts boron or phosphorus and (ii) a cocatalyst consisting of a soluble tungstic acid salt and/or an insoluble tungsten compound. 5. The composite catalyst of claim 1 , wherein the rare earth elements are a collective term for 17 chemical elements, with atomic numbers 21, 39 and 57-71, in group IIIB of the periodic table. 6. The composite catalyst of claim 1 , wherein the cocatalyst is a soluble tungstic acid salt selected from the group consisting of ammonium tungstate, sodium tungstate, sodium phosphotungstate and a combination thereof. 7. The composite catalyst of claim 1 , wherein the cocatalyst is an insoluble tungsten compound selected from the group consisting of tungsten trioxide, tungstic acid and a combination thereof. 8. The composite catalyst of claim 2 , wherein the cocatalyst is a soluble tungstic acid salt selected from the group consisting of ammonium tungstate, sodium tungstate, sodium phosphotungstate and a combination thereof. 9. The composite catalyst of claim 2 , wherein the cocatalyst is an insoluble tungsten compound selected from the group consisting of tungsten trioxide, tungstic acid and a combination thereof. 10. The composite catalyst of claim 3 , wherein the cocatalyst is a soluble tungstic acid salt selected from the group consisting of ammonium tungstate, sodium tungstate, sodium phosphotungstate and a combination thereof. 11. The composite catalyst of claim 3 , wherein the cocatalyst is an insoluble tungsten compound selected from the group consisting of tungsten trioxide, tungstic acid and a combination thereof. 12. The composite catalyst of claim 4 , wherein the cocatalyst is a soluble tungstic acid salt selected from the group consisting of ammonium tungstate, sodium tungstate, sodium phosphotungstate and a combination thereof. 13. The composite catalyst of claim 4 , wherein the cocatalyst is an insoluble tungsten compound selected from the group consisting of tungsten trioxide, tungstic acid and a combination thereof.
