Abstract
A method of preconditioning agglomerating coal particles to substantially prevent agglomeration of a fluid-bed reaction zone in a reactor comprising preheating thd coal particles in dense phase flow, rapidly oxidizing the particles in a vertical standpipe having a regulated thermal environment, pressurizing the particles to a pressure above reactor pressure and introducing the preconditioned coal particles into the fluid-bed reactor zone at substantially reaction pressure for reaction at an elevated temperature and at reaction pressure in the presence of a reagent.
