Title: Jan-Erik Hook: Innovator in Peroxide Bleaching Technology
Introduction
Jan-Erik Hook is a notable inventor based in Lilla Edet, Sweden. He has made significant contributions to the field of peroxide bleaching technology, holding two patents that showcase his innovative approaches. His work has implications for the pulp and paper industry, particularly in improving the efficiency of bleaching processes.
Latest Patents
Jan-Erik Hook's latest patents include a method for controlling peroxide bleaching in a plurality of bleaching processes and a method for use in the defibration or refining of lignocellulose fiber material. His patented method involves impregnating lignocellulose fiber with an aqueous silicate solution containing a sequestering agent. The impregnated fiber is then preheated with saturated steam, which precipitates silicic acid on and within the fibers. Following this, the preheated fiber mass is defibrated between two grinding discs in an atmosphere of saturated steam at temperatures ranging from 100 to 170 degrees Celsius. An alkaline peroxide solution free of silicate is introduced into the grinding space, enhancing the bleaching process.
