Title: Nils E Virkola: Innovator in Hemicellulose Processing

Introduction

Nils E Virkola is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of hemicellulose processing, holding a total of 3 patents. His work focuses on innovative methods that enhance the production and processing of cellulose materials.

Latest Patents

Virkola's latest patents include a process for the production of a hemicellulose hydrolysate and special pulp. This two-step process involves the prehydrolysis of the material, followed by the dissolving of lignin contained in the prehydrolyzed material. The lignin dissolving is achieved through neutral sulphite cooking with anthraquinone or a derivative as a catalyst, with the cooking liquor's pH initially set at least at 10. Another significant patent is a method for decreasing the viscosity of sulfate black liquor from the cellulose cook. This method improves the evaporability of the black liquor by raising its temperature above the cooking temperature, which splits the macro-molecular lignin fraction contained in the liquor.
