Screening sulfur trioxide

While the current catalyst screening is done at atmospheric pressure, commercial reactors would operate at pressures up to perhaps 20 atmospheres. The effect of pressure on the decomposition kinetics has to be explored. Therefore, a pressurized catalytic sulfur trioxide reduction reactor has been designed and plans for its construction and operation have been made.

Where screening smoke must be delivered by explosive action, and where at the same time smoke screens without fire hazard are desired, a solution of 55 parts of sulfur trioxide (SO3) in 45 parts of chlorosulfonic acid (CLSOjH) is cheap and effective though its screening power is about one-half or less that of phosphorus. This FS mixture and the more expensive and otherwise less desirable titanium tetrachloride (TiCL4) called FM become aerosolized droplets only in the presence of water and presumably display their power of obscuration best and fastest in humid air. 

Past studies have focused on not only the process evaluation using a commercial computer code, but also the screening test of the component structural materials. Experiments to develop the catalysts for sulfur trioxide and hydrogen iodide decompositions were carried out successfully, and their manufacturing technologies were established. The experimental feasibility test of a 3.5 NL H2/h-scale SI test facility under atmospheric operation conditions has been performed in early 2008. As a result, we secured the continuous operation hydrogen production data for 6 h.
