Optimization of pre-treatment process of glycerol residue for succinic acid production

The purpose of this study is to recover glycerol from the oleo-chemical industry waste through acid pre-treatment process. Pre-treatment intervals parameters (pH, temperature and mass substrate) was obtained from OFAT, while the optimum conditions for the recovery of glycerol obtained by using respo...
