Abstract
A two-stage coal gasification system in which high temperature synthesis gas produced in a downflowing gasifier containing a high quantity of sensible heat is subsequently reacted in a pyrolyzing reactor with a charge of carbonaceous material and limestone at a reduced temperature to utilize the sensible heat contained in the gas and simultaneously produce an increase in the hydrocarbon content thereof.
