Title: Innovations of Lawrence J Kirby in Coal Liquefaction

Introduction

Lawrence J Kirby is a notable inventor based in Littleton, Colorado, recognized for his contributions to the field of coal liquefaction. He holds two patents that showcase his innovative approaches to enhancing the efficiency of coal processing.

Latest Patents

Kirby's latest patents include a coal liquefaction process employing internal heat transfer. This process involves preheating a feed coal-solvent slurry in a thoroughly back-mixed preheater zone before passing it to a dissolver zone. Hot hydrogen is introduced downstream from the preheater zone, facilitating exothermic hydrocracking reactions. The effluent stream from the dissolver zone is then processed through a vapor-liquid separator, allowing for the efficient transfer of heat generated during the liquefaction process.

Another significant patent by Kirby is a coal liquefaction process utilizing selective heat addition. This method involves heating a portion of the total process hydrogen stream to a high temperature and mixing it with a portion of the coal slurry in the dissolver zone. The presence of recycle mineral residue catalyzes hydrocracking reactions, generating sufficient process heat to allow for the addition of the remaining slurry and hydrogen in a cooler condition.
