        This paper which was read before the 11^th International Congress of Pure and Applied Chemistry, explains the basic elements of the fluid solids technique and describes 3 special applications of this development in the petroleum field, namely, the catalytic processing of gas oils, the extraction of liquid fuels from shale, and the synthesis of the higher hydrocarbon homologs from natural gas.  Simplified diagrams showing the basic features of the above processes are shown.  Other applications are under active development, among which are the coking of residual fuel oils and the carbonization and gasification of coal.
