Syngas generation based on the conventional steam reforming process requires considerable amounts of process steam. Producing this steam has a major impact on the plant's energy bill. This industry is therefore looking for ways to reduce the steam-to-carbon (S/C) ratio of syngas generation. With conventional reforming catalysts, the reduction of steam can ultimately lead to or accelerate deactivation of the catalyst due to carbon accumulation and coke formation.
The stabilized crystal structure and tuned catalyst composition of BASF's SYNSPIRE™ G1-110 catalyst improves gasification activity and paves the way for coke-free operation under conditions with a low S/C ratio.
With conventional reforming catalysts coking is initiated through deposition and insertion of a carbon species from the vapor phase into the metallic nickel (Ni) particles. Carbon accumulates at these weak points, forming carbon “whiskers“ and soft coke. This ultimately leads to deactivation of the catalyst.
