METHOD OF HEAT RECOVERY Russian patent published in 2001 - IPC

FIELD: conducting catalytic reactions by liberated heat. SUBSTANCE: proposed method consists in catalytic transformation of low-concentrated gases at low initial temperatures by blowing fixed layer of catalyst by these gases when heating of gas mixture is effected by compression of this mixture; reaction is carried out under pressure; cooling the gas mixture after reaction is effected through expansion of this mixture, thus producing mechanical work. EFFECT: possibility of using heating capacity of low-concentrated gases for obtaining mechanical work; simplified technological scheme; reduced overall dimensions and mass. 2 dwg
