A PROCESS FOR PRODUCING ORGANIC COMPOUNDS WHICH COMPRISES INTRODUCING A FEED MIXTURE COMPRISING HYDROGEN AND CARBON MONOXIDE IN A MOL RATIO OF HYDROGEN TO CARBON MONOXIDE BETWEEN ABOUT 0.7:1 AND ABOUT 10:1 INTO A REACTION ZONE, PASSING A GASEOUS MIXTURE UPWARDLY THROUGH SAID REACTION ZONE AT A VELOCITY BETWEEN ABOUT 0.5 AND ABOUT 40 FEET PER SECOND IN THE PRESENCE OF A FINELY DIVIDED FLUIDIZED CATALYST UNDER CONDITIONS SUCH THAT A MAJOR PROPORTION OF SAID CARBON MONOXIDE IS CONVERTED, MAINTAINING IN SAID REACTION ZONE A TEMPERATURE BETWEEN ABOUT 350* F. AND ABOUT 750* F. AND A PRESSURE BETWEEN ABOUT 50 AND ABOUT 500 POUNDS PER SQUARE INCH GAGE, WITHDRAWING A GASEOUS EFFLUENT FROM SAID REACTION ZONE, RECYCLING A PORTION OF SAID GASEOUS EFFLUENT WHOSE TEMPERATURE IS NOT LOWER THA ABOUT 100* F. OF THE EFFLUENT TEMPERATURE TO SAID FEED MIXTURE
