Adsorbent for purifying vegetable oils from phosphorus containing compounds

摘要: A granulated composition comprising 5 to 50 percent of a metal oxide Group II or III the Periodic Table, mixture thereof, and 10 40 by weight cement which is heatresistant at 500*C above, 85 alumina clay free from iron oxides. The adsorbent prepared mixing an aqueous solution salt said metals with soda alkali while simultaneously depositing, stirring, resulting carbonates hydroxides onto clay. coated filler separated give paste-like mass mixed, stirring water granulated, dried 20* 150*C calcined temperature 300* 500*C. may be regenerated quite easily has high mechanical strength up 150 kg/cm2. use this for purification vegetable oils makes it possible reduce 500 times usual consumption, eliminate separating filtration, increase 2 2.5 service life catalysts employed in hydrogenation oils.
