    摘要： An integrated process providing for a gas phase hydro-oxidation of an olefin, preferably, propylene, with oxygen in the presence of hydrogen and a catalyst under reaction conditions such as to form a gaseous hydro-oxidation effluent stream containing an olefin oxide product, preferably, propylene oxide, water, unconverted olefin, oxygen, and hydrogen; and further providing for separation and recovery of the olefin oxide product from the effluent stream. The separation involves feeding the hydro-oxidation effluent stream into a first distillation column employing a liquid reflux rectification agent to obtain a first overhead stream containing unconverted olefin, oxygen, and hydrogen, which is recycled to the hydro-oxidation reactor, and a first bottoms stream containing water and the olefin oxide, from which upon further separation a purified olefin oxide product is recovered.

    摘要： A method to achieve a controlled start-up temperature of an expoxidation process which exceeds the maximum achievable temperature of the epoxidation reactor relative to using an external heat source. The method of the present invention employs an oxidation reaction within the reactor to bring the temperature of the reactor to a temperature that is suitable for conditioning a high selectivity catalyst. The method of the present invention includes first bringing a reactor including a high selectivity catalyst to a first temperature using the external heat source to the reactor, while staying within the reactor design limitations and maintaining a gas flow to the reactor that is within 25 to 100% of the design rates. Once the reactor has achieved the first temperature, at least an olefin, e.g., ethylene, and then oxygen are introduced to the reactor feed gas. The olefin and oxygen concentrations are adjusted to have a heat of reaction that will allow raising the reactor gas flow to 100% of design and then have sufficient heat of reaction to raise the reactor temperature to a second temperature which is greater than the first temperature and greater than the temperature of the reactor achievable by the external heat source.

    摘要： Described is a method of improving the process and operation of an existing system for manufacturing ethylene oxide. The ethylene oxide manufacturing system includes an epoxidation reactor system containing a volume of high activity epoxidation catalyst. The method includes replacing a portion of the volume of high activity epoxidation catalyst with a volume of high selectivity catalyst, and modifying the operation of the process system so as to provide for a feed to the epoxidation reactor system having a reduced carbon dioxide concentration.

    摘要： A vapor-phase tubular reactor in a shell heat exchanger for removal of the heat of reaction at essentially isothermal conditions has porous wicking surface (211) applied to the external surface of reactor tubes (210). The porous wicking surface on the reactor tubes draws liquid heat transfer fluid from a reservoir at the bottom of the wicked tube section and provides enhanced evaporative cooling. The invention is particularly useful for highly exothermic reactions or when reaction selectivity is negatively affected by high temperature excursions.

    摘要： Disclosed are improved processes for the recovery of 3,4-epoxy-1-butene (epoxybutene) from an epoxidation effluent comprising epoxybutane, butadiene, oxygen and an inert diluent obtained by the selective epoxidation of butadiene with an oxygen-containing gas in the presence of a catalyst and an inert gas. Epoxybutene is separated from the effluent by means of an absorption process using an extractant comprising liquid butadiene and, optionally, a hydrocarbon diluent. The formation of butenediols, by the reaction of epoxybutene and water, in the recovery process is inhibited by the addition of a base, preferably an alkali metal base, to the recovery system.
