Abstract
Fresh carbonaceous particles are introduced into a fluid-bed reaction zone containing a bed of non-agglomerating particles at an injection velocity in excess of about 200 ft/sec with the fresh particles having been preheated to a temperature within the plastic transformation range of the particles and introduced rapidly and directly into said bed of non-agglomerating particles. The reaction zone may be a hydrocarbonization zone, a carbonization zone, a gasification zone or any other fluid-bed reaction zone in which defluidization may be caused by undue agglomeration of the feed particles. A fluidized stream of the preheated carbonaceous particles may be introduced at said high injection velocity in a vertically upwards direction or otherwise, as from one or more injection points positioned vertically along the side of the reaction zone.
