Title: The Innovative Contributions of Karl N Cederquist
Introduction
Karl N Cederquist is a notable inventor based in Stockholm, Sweden. He has made significant contributions to the field of organic material combustion and fiberboard production. With a total of three patents to his name, Cederquist's work reflects a commitment to advancing sustainable practices in industrial processes.
Latest Patents
Cederquist's latest patents include a method for wet combustion of organic material. This innovative process involves oxidizing organic material dispersed in waste liquor from wood pulping processes. The method operates at temperatures ranging from 180°C to 340°C and utilizes superatmospheric pressure. The combustion occurs in two steps, first partially oxidizing the organic material to convert it into carbon dioxide and water, and then combusting residual fatty acids in the presence of oxygen-enriched air.
Another significant patent is the wet method of preparing fiberboard products in a substantially closed system. This method involves using a closed white water system to create fiberboard. It includes applying layers of separately prepared surface pulp to a base pulp layer during the wet sheet forming stage. The process utilizes lignocellulose chips in a pressure-sealed defibrating zone, generating steam that is then used to pre-steam raw chips. The innovative approach ensures efficient recycling of water and pulp, contributing to sustainable production practices.
