Abstract

In a process for steam reforming of oxygenates, especially at low steam-to-carbon (S/C) ratios, a feed gas containing oxygenates, such as ethanol, is converted into syngas over a ternary carbide catalyst. Then the reformed gas is either transformed into desired chemicals or mixed into the feed stream to the reformer in a plant, such as an ammonia or methanol plant. The preferred ternary carbide is nickel zinc carbide.

First claim

The invention claimed is:

1. A process for steam reforming of oxygenates, in which a feed gas containing oxygenates, is converted into syngas according to the reactions
C 2 H 5 OH+3H 2 O↔2CO 2 +6H 2 or

C 2 H 5 OH+H 2 O↔CH 4 +CO 2 +H 2

over a nickel zinc carbide catalyst, and which after use shows nickel solely in the form of alloys, where the syngas is subsequently either transformed into desired chemicals or mixed into a feed stream to a reformer in a plant selected from the group consisting of an ammonia plant and a methanol plant.
