ABSTRACT:
A method and arrangement of apparatus is provided for catalytically cracking liquid hydrocarbons to form gaseous and liquid fuel products and effect regeneration of the used catalyst particles whereby means are provided which improve separation of formed suspensions in a substantially reduced time frame and combustion of substantial hydrocarbonaceous deposits is accomplished under restricted temperature conditions contributing to catalyst life in a two stage catalyst regeneration operation of restricted elevation. The apparatus combination of the present invention is preferably of low vertical profile by restricting the vertical length of the riser contact zone in one embodiment by providing a substantial horizontal section thereof in a downstream portion of the riser.
