1. The configuration mounting technique appears to have an influence on mass temperature rise. Configurations 3, 4 and 14 were mounted with spacing between the individual ceramic discs, whereas configurations 5, 6, and 12 had discs apparently allows the gases exiting one disc to intermix and homogenously, and uniformly, react together before flowing into the passages of the next downstream disc. On the other hand, those discs packed tightly together tend to direct the mass flow through an almost continuous ceramic passage where most of the reaction can only be heterogeneous on the catalyst surfaces. the ceramic discs as close together as possible. The spacing between the
