Finishing of micro crystalline wax (MCW) using bauxite percolation to
obtain food grade quality product having acceptable colour and colour
stability has been studied. Deoiled MCW percolated over an activated b
auxite at a temperature of 110-130-degrees-C and flow rate varying bet
ween 0.2 to 0.7 bbl/ton h has been found to be comparable in quality w
ith that of reference sample and quality requirements prevalent in Ind
ia. Obtainable yield is comparable to the values reported in literatur
e.
