Development of CO2 reforming technology

A CO 2 reforming catalyst and process have been developed. The commercial scale CO 2 reforming catalyst has demonstrated its activity and stability in pilot plant tests under operating conditions for the manufacture of synthesis gas with a H 2 /CO ratio of 2.0 for approximately 7,000 hours. In these tests, synthesis gas was generated by CO 2 and H 2 O reforming with high energy efficiency: low CO 2 /carbon and low H 2 O/carbon ratios in feed gas composition. Our catalyst exhibited high carbon removal characteristics with steam from the catalyst surface, which prevents carbon deposition on our CO 2 reforming catalyst.

Advanced auto-thermal gasification process

Abstract The Advanced Auto-thermal Gasification (A-ATG) Process, developed through a large-scale national project in Japan, is a synthesis gas production process that combines ultra-deep desulphurization of a feed gas (i.e., natural gas) with a new, high performance reforming catalyst. The A-ATG catalyst allows the oxidation reaction and the reforming reaction to take place simultaneously and has a high activity and a high reaction rate. Therefore the amount of catalyst can be reduced to one fourth of that previously required by a conventional process using a pre-reformer. A pilot plant has demonstrated that the A-ATG Process results in a compact plant and reduced construction costs, and operation of this pilot plant has provided a firm basis for the development of commercial plants.
