The assessment of zeolite regeneration … WebThe 13X zeolite modification method was as follows. After mixing the 13X zeolite and 0.5 M HNO 3 in a ratio of 1 g of zeolite to 10 ml of HNO 3, the mixture was stirred in a water bath at 95 °C for 1 h. The modified support was filtered and washed thoroughly until the acid was completely removed and dried overnight before use.
WebIn addition, hydrogen sulfide is a highly flam-mable gas and gas/air mixtures can be explo-sive. It may travel to sources of ignition and flash back. If ignited, the gas burns to pro … WebIn this work, the TSA process uses 13X zeolite molecular sieves. 13X zeolites are available in pellet form with uniform pore size of 10A. These adsorbents are selective and have high affinity to adsorb both water and mercaptan. The adsorption characteristics of beds, such as pressure effect, bed height and operating time effects on
