Development of highly active catalysts for steam natural gas reforming process

摘要

Toyo Engineering corporation developed thecatalysts as titled above, whose high activity is realized by porestructure having meso pores and macro pores, and by well-dispersed and retained Ni particles. Commercial catalysts arecommonly controlled by the diffusional resistance and showsimilar activities under commercial operating conditions. Thedeveloped catalyst proved by 3-4 times as active as those in 2 yearscommercial operation and deposited carbon on the developedcatalyst was 1/3 of that on a commercial one. The developedcatalyst ahs commercial merits such as tube life extension ofreformer, saving fuel than use of commercial ones. The developedcatalyst can apply to Naphtha feed stock by a combination withpre-reforming catalyst.
