Title: Innovations of Si-Hyun Lee in Coal Modification and Carbon Dioxide Separation
Introduction
Si-Hyun Lee is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of energy research, particularly in the modification of coal and the separation of carbon dioxide from gas mixtures. With a total of 2 patents, his work is paving the way for more efficient energy solutions.
Latest Patents
One of Si-Hyun Lee's latest patents is a method for reforming coal using palm residue. This innovative method economically modifies low rank coal (LRC) into high-grade coal while minimizing water re-absorption and the risk of spontaneous ignition. The process involves coating the coal with heavy oil directly, without the use of solvent oil. The method includes milling the coal, mixing it with palm oil residue, melting the residue to coat the coal, and drying and briquetting the final product.
Another significant patent is a method of separating carbon dioxide from a gas mixture using biopolymer. This method introduces hemocyte or extrapallial fluid extracted from shells into a reactor containing a calcium source solution. The hemocyte is dissolved to form a mixed solution, into which carbon dioxide or a gas mixture containing carbon dioxide is mixed, effectively separating the carbon dioxide from the gas mixture.
