It is found that the first or zero order with respect to the catalyst can be observed for this process in the regime of external diffusion limitation for the gas reagents, depending on the concentration of the catalyst in the suspension, and the selectivity toward solid products (hydroxylamine sulfate (HAS) and ammonium sulfate) is greatest in the region of transition.
