    摘要： Elastomeric polymer blends and processes for their production are described. Specifically, the polymer blends comprise a first polymer and a second polymer, where the first polymer comprises from about 70 wt % to about 90 wt % units derived from propylene and from about 10 wt % to about 30 wt % units derived from ethylene and/or a C4-C10 alpha-olefin, and the second polymer comprises from about 88 wt % to about 98 wt % units derived from propylene and from about 2 wt % to about 12 wt % units derived from ethylene and/or a C4-C10 alpha-olefin. The elastomeric polymer blends are further characterized by having two or more of the following properties: an overall propylene content of between about 75 wt % and about 90 wt %, a melting point between about 110° C. and about 145° C., a Vicat softening point greater than about 45° C., a tensile stress at 300% strain of less than about 500 psi (3447 kPa), as determined by a stress strain test according to ASTM D412, or an average maximum force for pellet separation of less than about 10 N in an accelerated storage stability test. The polymer blends are produced in a dual reactor process, in which the first polymer and the second polymer are prepared using differing catalyst systems.

    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.

    摘要： Reactor designs and processes for operating such reactor designs to minimize or eliminate fouling in homogeneous polymerization processes (solution and supercritical). The process includes providing a reactor with one or more feed entry ports, wherein the reactor feed components are fed through each of the one or more feed entry ports at a linear velocity of greater than or equal to 0.3 m/min. The one or more feed entry ports may also be optionally extended beyond the interior reactor wall by greater than or equal to 2% of the internal radius of the reactor to further decrease the propensity for fouling. A stirred reactor may also include a stirrer feed port for purging the stirrer with a stirrer purge stream at a linear velocity of greater than or equal to 0.3 m/min to decrease stirrer fouling.

    摘要： In a process for selectively separating 1-butene from a C4 feed stream comprising at least 1-butene, cis-2-butene and trans-2-butene, the feed stream is passed through a first bed of an adsorbent comprising a crystalline microporous material to form a substantially trans-2-butene-free effluent stream. Then, the substantially trans-2-butene-free effluent stream is passed through a second bed of an adsorbent comprising a crystalline microporous material to form a substantially 1-butene-free effluent stream, whereby the 1-butene is separated from the feed stream. The adsorbed 1-butene is then typically desorbed from the second adsorbent bed either by lowering the pressure or raising the temperature of the bed.
