    摘要: A process for producing polyethylene resins containing carbon black in a gas fluidized bed reactor which comprises introducing into said reactor, polymerizable monomers capable of producing polyethylene resins at polymerizable reaction temperatures in the presence of a catalyst while directly introducing into said reactor during said polymerization, carbon black, in an amount to produce said polyethylene resins containing carbon black.

    摘要: A process for the separation of ethanol from water using solvent extraction at elevated pressures is disclosed. Separation is effected by contacting aqueous ethanol with either propylene (propene), allene (propadiene), methyl acetylene (propyne), or methyl allene (1,2-butadiene). This produces two liquid phases which separate because of the difference in their densities, and are easily drawn off as separate streams. The solvent is recovered by distillation and condensation using a heat pump to transfer heat. The ethanol and water remain in a liquid state and are substantially recovered.

Separation is effected by contacting aqueous ethanol with either propylene (propene), allene (propadiene), methyl acetylene (propyne), or methyl allene (1,2-butadiene). This produces two liquid layers which separate because of the difference in their densities, and are easily drawn off as separate streams. The solvent is recovered by reverse osmosis means in a liquid state. The ethanol and water remain in a liquid state and are substantially recovered.
