Abstract:
1. Power generation apparatus comprising: a gas-fueled power generator; two-stage reaction apparatus for producing a fuel gas product from a hydrocar-bonaceous material, operatively connected to supply fuel gas to said power generator, said reaction apparatus including a pyrolysis chamber comprising a first stage thereof, and a second chamber containing a non-consumable catalyst, comprising a second stage thereof and means for controlling the flow of fuel gas from said reaction apparatus to said generator, said reaction apparatus being constructed to enable effecting a process comprising the following steps: (a) introducing a non-gaseous hydrocarbonaceous material into said pyrolysis chamber; (b) pyrolyzing the hydrocarbonaceous material in said pyrolysis chamber so as to produce a primary fuel gas mixture, a pyrolysis liquid, and a first carbonaceous residue; (c) introducing the primary fuel gas mixture and the pyrolysis liquid into said second chamber, and heating said liquid therein, in a substantially non-oxidizing atmosphere, to a temperature of 900° to 1100° C. and substantially above the temperature at which pyrolysis is effected in step (b), so as to produce additional fuel gases and additional solid carbonaceous residue, without substantially altering the composition of said primary fuel gas mixture; (d) withdrawing the primary fuel gas mixture and the additional fuel gas from said second chamber; and (e) introducing air, oxygen, carbon dioxide or steam into each of said chambers to effect reaction with, and at least partial removal of, said carbonaceous residue therein; and electronic data processing means programmed for monitoring the formation of at least one gas phase product and for controlling said steps (a) through (e), carried out batchwise as a cycle, based upon such gas phase product formation monitoring.
