Abstract:
Glycerin produced from biodiesel was purified using a series of methods. Crude glycerin was separated from
biodiesel by gravity settling and by centrifugaiton. Methanol and catalyst used in the production of biodiesel was removed by distillation and acidulation using HCl respectively. The colour and odour of glycerin was
reduced using Bacterial cellulose(BC) synthesized by Acetobacter xylinum. The purity of glycerin was seen to
increase after each treatment, glycerin from biodiesel had 5.18% glycerin, after methanol removal the glycerin
content was, 13 -1%. after the removal of catalyst and FF. I the glycerin content
was 20. 7%, after the reduction
of colour and odour by adsorption using BC. the glycerin content was 33%.
