Synthesis and characterization of catalysts for the production of lactic acid from biomass residues.

Annually, the global dairy industry generates more than 200 million tons of whey, with cheese production being a significant contributor. Approximately every kilogram of cheese produced generates 9 liters of whey waste, presenting financial and environmental challenges due to its high organic content. Lactose, one of the most abundant components of cheese whey, is an economical raw material for synthesizing valuable compounds.

In this project, we propose a catalytic process that converts an aqueous lactose solution into high-value products, notably lactic acid. This conversion takes place within a fluidized bed reactor employing catalytic materials. The intern’s responsibilities include characterizing the catalyst, which was previously synthesized in Canada, and comparing it with materials developed at the host institution. Following the selection of catalysts with the desired physicochemical properties, the intern will conduct testing in Canada. We anticipate that the synthesis of the new catalyst will result in particles with a size of less than 200 micrometers, ideal for fluidization. These catalysts are expected to contain acid sites that promote acid conversion while preventing the formation of undesirable byproducts.
