Title: Innovations of Pedram Fatehi in Lignin Copolymer Synthesis
Introduction
Pedram Fatehi is an accomplished inventor based in Thunder Bay, Canada. He has made significant contributions to the field of lignin copolymer synthesis, holding a total of 4 patents. His work focuses on developing innovative processes that enhance the properties and applications of lignin-based materials.
Latest Patents
Fatehi's latest patents include a process for producing cationic lignin copolymer under aqueous acid conditions. This water-based process synthesizes aminated lignin copolymers with high molecular weight, thermal stability, and solubility in water across a wide range of pH values. The cationic lignin copolymer features a grafting ratio of 70 to 200% and a charge density of +1.4-3.0 meq/g. This innovation can be utilized as a flocculant in various wastewater streams, including municipal and industrial systems, as well as sludge dewatering in the pulp and paper, mining, and oil industries.
Another notable patent is the process for producing an anionic lignin copolymer under aqueous acid conditions. This acidic water-based process allows for the synthesis of anionic lignin copolymers with adjustable molecular weight, thermal stability, and solubility in water. The anionic lignin copolymer has a molecular weight ranging from 5,000 to 7.4×10 g/mol and a charge density of -1 to -7.2 meq/g. These copolymers can serve as dispersants for negatively charged molecules or particles in various processes or wastewater streams, such as concrete admixtures and textile dye, while those with higher molecular weights can act as flocculants in industrial and municipal systems.
