Abstract
Official abstract text for this publication.
An acid-resistant alloy catalyst, comprising nickel, one or more rare earth element, tin, aluminum and molybdenum. The catalyst is cheap and stable, does not need a carrier, can be stably applied in industrial continuous production, and can lower the production cost.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acid-resistant alloy catalyst, characterized in that the acid-resistant alloy catalyst comprises nickel, one or more rare earth element, tin, aluminum and molybdenum, wherein the catalyst does not contain tungsten. 2. The acid-resistant alloy catalyst as claimed in claim 1 , characterized in that the acid-resistant alloy catalyst comprises, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin, 5-9 parts aluminum and 0.1-20 parts molybdenum. 3. The acid-resistant alloy catalyst as claimed in claim 1 , characterized in that the acid-resistant alloy catalyst comprises nickel, one or more rare earth element, tin, aluminum, molybdenum and boron or phosphorus. 4. The acid-resistant alloy catalyst as claimed in claim 3 , characterized in that the acid-resistant alloy catalyst comprises, in parts by weight, 10-90 parts nickel, 1-5 parts rare earth element, 1-60 parts tin, 5-9 parts aluminum, 0.1-20 parts molybdenum and 0.01-5 parts boron or phosphorus. 5. The acid-resistant alloy catalyst as claimed in claim 1 , characterized in that the rare earth element is a general designation for 17 chemical elements with atomic numbers 21, 39 and 57-71 in group IIIB of the periodic system.
