THE EFFECT OF NICKEL-CATALYST GRANULATION ON ITS ACTIVITY IN THE PROCESS OF THE RAPESEED OIL HYDROGENATION AND ON THE FILTRATION-RATE

The hydrogenation of the rapeseed oil was conducted under the atmosphe ric and 0,3 MPa pressure with nickel catalyst from Fertilizer Institut e Pulawy and an imported one. The catalysts investigated varied in gra in size It was found out that the size of the catalyst grain affected the rate of hydrogenation and filtration of catalyst from oil. The cat alyst showed different activities. The highest activity was noted for fined-grained catalyst. A medium one was observed in the case of mixed catalysts, while the smallest one for coarse-grained one. However, th e filtration rate was the highest for coarse-grained catalysts.
