Abstract

Experimental studies have been carried out to clarify the possibility of adsorption removal of malodorant gases such as ammonia, hydrogen sulfide and methylmercaptan from various environments by zeolite tuffs. The test was conducted by the Colomun method using pellets of Clinoptilolite and Mordenite. Various binding agents, i. e. magnesium silicate, sodium silicate, etc. , were added for pelletizing the powder zeolite tuffs. The results of the experiments are as follows: The adsorbing capacity of these pellets for malodorant gases depended upon the molecular diameter of these gases. When the malodorant gases adsorbed were ranked according to their quantities, from the largest to the smallest, then their order was 1) ammonia, 2) hydrogen sulfide, 3) methylmercaptan. Mordenite has a larger void diameter than that of Clinoptilolite and showed a higher absorbing capacity for these gases.
