Abstract :
The true reasons of decrease in efficiency of "breathing" gases cleaning of tanks and railway tanks from methanol on CJSC "Methanol" (Tomsk, Russia) are determined. Platinum catalyst aging is caused by sintering and partial destruction of ceramic blocks owing to excess of ultimate service temperature, blocking of the active centers by coke, nonoptimum working of the catalytic installation. The economic way of block platinum catalysts regeneration is developed. Also the kinetics of the methanol deep oxidation on platinum and metal-complex catalysts is investigated. Moreover optimal operation of installation for "breathing" gases purification is defined.
