    摘要： Synthesis gas is produced though a cyclic method where the first step of the cycle includes reforming a hydrocarbon feed over a catalyst to synthesis gas in a first zone of a bed and the second step reheats this first zone. A hydrocarbon feed is introduced to a bed along with CO2 and optionally steam where it is reformed into synthesis gas. The synthesis gas is collected at a second zone of the bed and an oxygen-containing gas is then introduced to this second zone of the bed and combusted with a fuel, thereby reheating the first zone to sufficient reforming temperatures. Additionally, a non-combusting gas can also be introduced to the second zone to move heat from the second zone to the first zone.

    摘要： A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for recovery and/or subsequent hydrocarbon synthesis. Sources of a light hydrocarbon gas, such as methane, and oxygen or an oxygen-containing gas are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired relative proportions, at a plurality of mixing nozzles which are open to the catalytic partial oxidation reaction zone and are uniformly-spaced over the face of the injector means, to form a reactant gaseous premix having a pressure drop equal to at least about 3% of the lowest upstream pressure of either of said gases. The gaseous premix is injected in a time period which is less than its autoignition time, preferably less than 9 milliseconds, at a velocity between about 25 to 1000 feet/second, into a catalytic partial oxidation zone so that the gaseous premix reacts in the presence of the fixed catalyst to reduce the amounts of CO2, H2O and heat produced by the partial oxidation reaction, to form a useful syngas which is cooled and recovered.
