Title: Innovations in Coal Liquefaction by Srikant Gir
Introduction
Srikant Gir is an accomplished inventor based in Memphis, TN (US). He has made significant contributions to the field of coal liquefaction, holding a total of 2 patents. His innovative methods aim to enhance the efficiency and effectiveness of coal processing.
Latest Patents
Srikant Gir's latest patents include a multi-stage coal liquefaction and fractionation method. This method involves slurrying coal with a primary light solvent, such as toluene, hexane, and/or cyclohexane, along with a process-derived primary heavy solvent. The coal-primary solvent slurry is treated under coal-liquefying conditions to create a first feed solution containing coal liquefaction products. This solution undergoes a multi-stage supercritical solvent extraction procedure. The final heavy phase produced is mixed with a secondary solvent, such as pentane, to create a second feed mixture, which is then treated in a second multi-stage supercritical solvent extraction procedure. The heavy phases recovered from both extraction procedures are blended to provide a recycled primary heavy solvent.
Another notable patent by Srikant Gir is a method of liquefying coal using a process solvent that comprises at least partially hydrogenated coal tar material. In this method, coal is mixed with the solvent to produce a coal-solvent slurry. This slurry is treated under coal-liquefying conditions, preferably in a hydrogen atmosphere and at elevated temperatures, to yield a solution containing coal liquefaction products. The recovered products can be recycled to supplement the process solvent.
