Title: Innovations by Inventor Fred L. Schmidt in Lignocellulose Pretreatment
Introduction
Fred L. Schmidt, a prominent inventor based in Camas, WA, has made significant contributions to the field of lignocellulose pretreatment with a total of three patents to his name. His innovative approaches have aided in advancing the efficiency of papermaking processes, thereby optimizing the usage of raw materials and reducing environmental impacts.
Latest Patents
Fred’s most recent patents showcase cutting-edge techniques that enhance the processing of lignocellulosic materials. One notable patent is for the continuous countercurrent pretreatment of lignocellulose, where the lignocellulose is treated with an alkaline pretreatment liquor containing anthraquinone or similar agents. This process flows in a countercurrent manner, allowing for effective recycling of the pretreatment agent, which is substantially soluble in the input liquor and insoluble in the withdrawn liquor.
Another key patent focuses on the pretreatment of lignocellulose with anthraquinone prior to the pulping process. By incorporating an alkaline pretreatment liquor with anthraquinone, Fred's method increases pulp yield while reducing the amount of alkali required. This approach maintains at least 50% of anthraquinone in the pretreatment liquor, which can be separated and reused for subsequent pretreatments.
