تحضير و تشخيص العامل المساعد(Co,Mn)(Co,Mn)2O4-CaO و دراسة فعاليته في ازاله الهيدروجين من كحول الايزوبروبانول و تحويله الى اسيتون

Abstract

The catalyst (Co,Mn)(Co,Mn)2O4-CaO was prepared by coprecipitation method by adding (1M) of sodium carbonate as aprecipitating agent at constant pH (10).The precipitate of carbonate was dried at 120oC for 24 hrs and then calcined at different temperatures (400,500,600,700,800) oC for 4 hrs.The identification of the prepared catalyst was done by using the X-ray diffraction(XRD), thermal gravimetric analysis (TGA), scanning electron microscopy techniques (SEM) and BET measurements. The activity of this catalyst was investigated in dehydrogenation of isopropanol alcohol. The reaction results were followed by mass spectroscopy technique
