Abstract

The evaluation of plant performing gas phase glycerol hydrogenolysis is presented. The study is based on experimental data obtained in our laboratory. Information about the glycerol conversion and selectivity towards several interesting products was obtained by experiments performed over a copper-chromite catalyst in a fixed-bed reactor. The main product was 1,2-propanediol, by-products as acetol and propanol being also observed. The following set of operating conditions was selected for further evaluation: reaction at 240°C, 20 bar and 1 Nm3/L hydrogen : glycerol ratio, leading to 93% glycerol conversion and 72% selectivity towards 1,2-propanediol. The design of a glycerol hydrogenolysis plant was performed in AspenPlus. Economic evaluation lead to a Total Annual Cost of 2701 103 US$ / year, for a production of 14500 tonnes/year 1,2-propanediol.
