摘要： Disclosed is a system of making an olefin derivative from a dilute olefin feed. Dilute olefin is sent to an olefin reaction unit to form an olefin derivative product. The olefin derivative product is recovered from the reaction unit while a vent stream is also removed. Olefin is separated from the vent stream, and the olefin is sent to the olefin reaction unit for additional processing.

摘要： The present invention is a high efficiency reformed methanol (syngas) gas turbine power plant. The invention utilizes a Back Pressure steam Turbine (BPT) to maximize the thermal efficiency and the power output of a reformed methanol gas turbine power generation system. Methanol feed is reformed to syngas (H.sub.2 and CO.sub.2) prior to combustion in the BPT turbine. The endothermic reforming reaction, and the generation of the significant amount of process steam essential for reforming, recovers most of the useful heat in the gas turbine exhaust gas. The process steam pressure is set by the gas turbine inlet requirements, and can be referred to as low pressure steam. Additional heat in the gas turbine exhaust gas is recovered by generating the system's process steam at an elevated pressure, rather than the required low pressure. This high pressure steam is used to drive a BPT, generating additional power and the discharged low pressure steam from the BPT is used as the process steam for the methanol reformer.

摘要： A gas-solids reaction system is provided for improving product recovery in a multiple reactor reaction system. An oxygenate feedstock, desirably of high concentration in oxygenate, is reacted with a catalyst having a low to modest acidity and a Si/Al2 ratio of from 0.10 to 0.32. The reaction occurs in a reaction zone of a fluidized bed reactor at an oxygenate partial pressure of at least 45 psia and a reactor gas superficial velocity of at least 10 ft/s, conveying catalyst through the reaction zone to a circulation zone. The catalyst undergoes displacement with an inert gas in the circulation zone at a displacement gas superficial velocity of at least 0.03 m/s, after which at least a portion, preferably a large portion is returned to the reaction zone. The catalyst has a residence time in the circulation zone of at least twice that of the residence time of catalyst in the reaction zone. Extraordinary catalyst activity at high olefin selectivity results despite insignificant changes in coke on catalyst and coke yield when compared to lower pressure operations.
