摘要： THE DIRECT REDUCTION OF IRON ORE IS IMPROVED BY PASSING THE ORE DOWNWARDLY THROUGH AN INITIAL NON-FLUIDIZED OR HINDERED-FALL REDUCTION ZONE IN COUNTERCURRENT CONTACT WITH REDUCING GAS TO PARTIALLY REDUCE THE ORE TO WUSTITE. THE WUSTITE PRODUCED IN IMMEDIATELY ADDED TO A FERROUS REDUCTION ZONE IN WHICH THE ORE IS FLUIZED AND REDUCED TO A HIGHLY METALLIZED MATERIAL. THE PROCESS ELIMINATES THE NEED FOR AN ORE PREHEATER.

摘要： In a fluid coking process in which coke from the coker is passed to a heater and then to a gasifier and in which part of the heat for the heater is supplied by the gases from the gasifier, ungasified coke from the bottom of the gasifier is conveyed through a riser to the heater to supply additional heat and thence back to the coker whereby strength of the coke is increased by fresh coke deposition and in which all the oxygen is injected into the lower gasifier bed thereby eliminating possibility of oxygen breakthrough. The same results can be accomplished by passing the coke from the gasifier directly back to the coke reactor and eliminating the coke stream from the upper heater bed to the reactor.
摘要翻译： 在来自焦化器的焦炭通入加热器然后进入气化器并且其中加热器的部分热量由来自气化器的气体供应的流化焦化工艺中，来自气化器底部的未气化焦炭被输送 通过提升器到加热器以提供额外的热量，然后返回到焦化器，由此通过新鲜焦炭沉积增加焦炭的强度，并且其中所有的氧气被注入到下部气化器床中，从而消除了氧气穿透的可能性。 通过将来自气化器的焦炭直接返回到焦炭反应器并且将上游加热器床的焦炭流除去反应器，可以实现相同的结果。

摘要： 1. A TWO-STEP PROCESS FOR ACTIVIVATING FLUID COKE FOR USE IN REMOVING ORGANIC CONTAMINANTS FROM WASTE WATER WHICH COMPRISES CONTACTING SAID FLUID COKE TO EXOTHERMICALLY PARTIALLY ACTIVATE SAID COKE WITH A GASEOUS STREAM CONTAINING OXYGEN IN A FLUID BED REACTION ZONE AT A TEMPERATURE IN THE RANGE OF FROM ABOUT 500* TO ABOUT 800* F. FOR A PERIOD OF TIME TO CONVERT ABOUT 15 TO ABOUT 35 WEIGHT PERCENT OF THE FLUID COKE TO GASEOUS PRODUCTS AT A CONVERSION RATE IN THE RANGE OF FROM ABOUT 1 TO ABOUT 4 WEIGHT PERCENT AN HOUR AND THEREAFTER PASSING SAID PARTIALLY ACTIVATED FLUID COKE INTO A SECOND FLUID BED
REACTION ZONE WHEREIN SAID PARTIALLY ACTIVATED FLUID COKE IS CONTACTED WITH A GASEOUS STREAM CONTAINING STREAM TO ENDOTHERMICALLY REACT WITH AND FURTHER ACTIVATE SAID PARTIALLY ACTIVATED AT A TEMPERATURE IN THE RANGE OF FROM ABOUT 1400* TO ABOUT 1650* F. IN ORDER TO CONVERT FROM ABOUT 45 TO ABOUT 70 WEIGHT PERCENT OF THE TOTAL FLUID COKE TO GASEOUS PRODUCTS, AND RECOVERING SAID ACTIVATED FLUID COKE.
