摘要： A process for producing isooctane by introducing a butane feed stream (containing n-butane, i-butane) and hydrogen into a catalytic hydrogenolysis reactor to produce a hydrogenolysis product stream; separating the hydrogenolysis product stream into a butane stream (i-butane, optionally n-butane); feeding the butane stream to a catalytic dehydrogenation reactor to produce a dehydrogenation product stream comprising saturated and unsaturated four-carbon hydrocarbons; and feeding the dehydrogenation product stream to an oligomerization unit to produce isooctene and dehydrogenating the isooctene to produce isooctane.

摘要： Systems and methods for separating a mixture comprising C4 hydrocarbons and a solvent have been disclosed. The mixture is produced as a bottom stream of a rectifier column. The mixture is processed in at least two heating and flash-evaporating cycles to remove at least some C4 hydrocarbons as vapor streams. The resulted liquid stream is further degassed in a degasser column to produce a recycle vapor stream and a lean solvent stream.

摘要： An ultra-high molecular weight polyethylene polymer has: a powder bulk density of at least 200 kg/m3; an intrinsic viscosity (I.V.) of at least 8 dl/g, as measured in accordance with ASTM D4020; and wherein, a specimen prepared from the ultra-high molecular weight polyethylene can be drawn in the absence of a solvent, at a total draw ratio of at least 50, when drawing at a drawing temperature of ≥Tm−30° C., wherein Tm is the melting temperature of the ultra-high molecular weight polyethylene polymer. A supported catalyst system for producing such UHMWPE polymers includes a transition metal complex and a particulate catalyst support including particles having a volume based median particle diameter of at least 0.3 micrometer. Articles derived from such polymers having excellent strength and modulus.
