2018 JKM wiki IMPREGNATION AND CHARACTERIZATION OF K-DEOILED SPENT BLEACHING EARTH (K-DSBE) WITH WET METHOD
Abstract
In this research, KOH has been impregnated on Deoiled Spent Bleaching Earth (DSBE) with wet
method as a catayst. KOH was impregnated on DSBE of 40 % and 60 % (w/w), then characterized using XRay Flourescence (XRF), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), surface area test
and alkalinity test. The XRF analysis results showed that potassium oxide composition increased after
impregnation. The XRD analysis results show that DSBE belongs to the rectorite type of Na-montmorillonite,
whereas the SEM analysis results indicate a morphological change in DSBE. K-DSBE catalysts 40 % and 60
% KOH impregnation have a basicity of 1.46 mmol/g and 1.55 mmol/g with a surface area of 23.81
m2/g and 23.56 m2/g.
