Why Levulinic acid ? Platform Chemical Levulinic acid - Market share by application (current) • Current traded volumes : 3000-3500 MTA • Major supplier : China • Price : $4-7 per kg High price deterrent for market expansion Potential Market Opportunity $ 40 Billion Plasticizer $ 11 Billion Solvent Market Volumes Market $ 11 Billion Sp. polymers $ 1/Kg $ 2//Kg Price Replacement potential of 50 million MTA worth US$20 Bn if produced at <$1/kg Levulinic acid - Reaction Pathways First synthesis reported in 1840 by Prof. Mulder Levulinic acid - Challenges • Feed stock : • Sugars : Glucose, Fructose, Sucrose • Food vs chemical • Biomass (LC) • Complex • Higher sugar costs • Conversion technology : • Strong mineral acid catalyst • High temperatures • Low yield • Formation of humins/char • Reactor fouling • Separation : Difficult to separate LA from acid, humins and formic acid • Equipment Fouling Challenge to commercialization Identification of right feedstock Feedstock Advantages Challenges Starch Single sugar – Glucose Low yields Clean Competing with food Easy access Available in quantities HFCS Good yields Cost Clean feedstock Competing with food Available in quantities Poor selectivity on Glucose part Biomass No competition with food Higher cost of fractionation Abundant availability and obtaining sugars Huge CAPEX Molasses Low cost High Inorganic impurities Easy access Mixed sugars – different Available in quantities kinetics Non competing with food © Praj Industries Ltd www.praj.net 11 Current Technologies Technology Feedstock Status Segetis Current feedstock – Pilot facility of 80TPA operating in Minnesota HFCS since Oct 2013. Commercial scale target 22 MPPA (funding from IRRRB and Dept of Agri.) GF Biochemicals, Carbohydrate Currently operating a continuous process Caserta, Italy feedstock pilot with capacity 2000 TPA LA (??) Plan to set up a plant with capacity 10,000TPA LA by 2015, eventually 40,000TPA LA by 2018. Biofine Variety feedsock @ Pilot on variety of feedstocks for several years pilot; @ 1MTPD dry biomass Manufacturing Commercial plant expected to be in service with Waste by Q42015 based on waste cardboard. Cardboards. Capacity – 125 dry feed TPD.
