dc.description.abstractThis research is focused on developing a method that is applicable to the industrial-scale production of propylene glycol from glycerol with considerably high conversions and yields. The fundamental understanding behind this glycerol technology paves the way for future work on exploring some more commodity chemicals that will be derived from natural resources. Acetol was successfully isolated from dehydration of glycerol as the transient intermediate indicates that the reaction process for producing propylene glycerol with high selectivity can be done in two steps. Reactive distillation technology was employed to shift the equilibrium towards the right and achieve high yields. This catalytic process provides an alternative route for the production of propylene glycol from renewable resources. The low-pressure vapor-phase catalytic processing using copper-chromite catalyst has been proven as feasible for producing propylene glycol from glycerol. This approach was demonstrated in a continuous process to address the concerns of scalability and suitability for large scale production. The vapor-phase reaction approach allows glycerol to be converted to propylene glycol in a single reactor. A two-step reaction process to produce propylene glycol from glycerol via an acetol intermediate was proposed and validated. A large scale process is thereby potentially viable.eng
