Pilot plant production of pulp, linear lignin and xylose

摘要

The process developed by CIMV is a world premiere for the manufacture of whitened paper pulp, sulfur free linear lignin and xylose syrup from cereal straw. Indeed, this new technology allows the separation without degradation of the three main components of the vegetable matter which are the cellulose, the hemicelluloses and the lignins. It is about a vegetable refinery working on the model of an oil refinery. The organic acids are then recycled by evaporation from the organic solution. The remaining syrup is treated with water to precipitate lignins which are after easily separated. The development at an industrial scale which is scheduled for June 2006 will allow to create 130 to 150 jobs by factory designed to treat 120.000 tons of dry fibre annual plants per year.
