Abstract:
A method is disclosed for treating residues from biodiesel production for the isolation of highly pure potassium sulphate from potassium sulphate-containing sludge. First, potassium sulphate-containing sludge from biodiesel production is heated in the first stage under non-oxidizing conditions to a material temperature between 400 and 700° C.; in a second stage the product from the first stage is heated under oxidizing conditions to material temperatures between 700 and 900° C.
