Kim, Juyeon published the artcileBio-based process for the catalytic production of ethyl levulinate from cellulose, Category: esters-buliding-blocks, the main research area is ethyl levulinate cellulose catalytic production.
This paper presents a bio-based process for the catalytic conversion of cellulose to Et levulinate and an anal. of its techno-economic feasibility. The said bio-based process relies as major feedstock on cellulose, which can be derived from lignocellulosic biomass. Cellulose is converted to Et levulinate via a homogeneous catalytic reaction whereby dilute sulfuric acid in combination with Al salts is the catalyst and ethanol is the solvent and reactant. This approach affords high Et levulinate yields but requires complex procedures for used catalyst and solvent recycling. Based on exptl. results on the homogeneous catalytic reaction and vapor-liquid equilibrium separation in the previous studies, a simulation was conducted that included process design, energy integration, and economic anal. Results from this simulation indicated the proposed bio-based process to afford a min. selling price of US$ 2,830 per ton of Et levulinate, which was highly dependent on an off-site supply of heating energy required for ethanol purification
