| Abstract: | A method of dilute ethylene recovery by AgNO3 solution was developed by spreading the bulk liquid into micron-scale droplets or films over the inside surface of the porous media,so that the absorption efficiency of the solution could be utilized to the largest extent by keeping the absorbing characteristic of ions in liquid.In studying the effects of solid surface charge property on absorption,porous medium diatomite was firstly treated with hydrochloric acid and calcined to remove the impurities.The crude ... |
