Project DescriptionEdit

Our project is dedicated to the process design for the conversion of sorbitol to the following: glycerol , ethylene glycol , propylene glycol , alcohols, and other byproducts. The goal of this work is to produce propylene glycol and ethylene glycol in approximately a 2:1 ratio while having converted more than 60 wt% of the sorbitol feed. In order to convert the sorbitol feed into the products, a ruthenium catalyst supported on activated carbon was chosen. This catalyst will then be continually fed into an upflow slurry-phase reactor. The process we are designing will also incorporate a bioreactor to convert the byproduct glycerol into 1,3-propanediol .

It is important to note that all of our current information can be found in the informational handouts.  All updated materials are also found on the UIC Engineering EXPO page.
