In this study, organic amines were used to modify zeolite NaA and analcime synthesized using fly ash iron tailing slag as raw materials, respectively, the adsorption properties of modified zeolites toward CO2 determined. We found that when tetraethylenepentamine (TEPA) was used, had highest nitrogen content. The capacity for 4.02 mmol/g 1.16 temperature 70 °C flow rate 50 mL/min. According isot...
Liquid fuel dimethyl aminoethyl azide (DMAZ) has been attended by many researchers as a new green fuel in recent years. Ssynthesis of the fuel has led to a process contains dehydration of DMAZ as a highlighted section. In this study, dehydration of DMAZ/water solution has been investigated by using four different zeolite membranes as HSOD, NaA, LTT and NaX that cover different pore sizes. Many ...
Abstract The performance of zeolite membrane supports directly determines the synthesis and industrial application membranes. In this study, a novel high permeation SiC for NaA were prepared by carrying out in situ reaction bonding at temperature air atmosphere to coat particles with aluminum sol. effects process parameters on formation porous structure systematically investigated, underlying m...
The activation of soil-fixed phosphorus is a long-term concern in soil science. In order to enhance the activation effect to soil-fixed phosphorus in red soil, different modified zeolite, through physical, chemical method and the associated both physics and chemistry, was used in this paper. The results showed as following: 1) the activated ability to soil-fixed phosphorus in red soil for modif...
