Development of a Sulfur Tolerant CHG Process [Abstract]

Abstract

The goal of this project is to overcome CHG catalyst sulfur poisoning to enable commercially viable CHG processing of HTL aqueous waste streams with reasonable catalyst turn-over rates. If successful, several of the following objectives will be achieved. (1) Identification and confirmation of the efficacy of sulfur-tolerant catalyst for the conversion of soluble organics in HTL aqueous byproduct to methane or hydrogen. (2) Demonstration of long-term stability of sulfur tolerant catalysts. (3) Identification and exercise of a means to produce larger quantities of the promising catalyst (i.e., sufficient catalyst for a CHG system with a through put of 10 to 20 L/h of aqueous byproduct) (4) Demonstration of the technical feasibility of a novel sulfur removal process and approach for scale up and application.
