The method of isolating products of an oligomerization reaction of olefins including a terminal double bond, in which the reaction is carried out by the action of a catalyst having chromium compounds, a nitrogen-containing ligand and organoaluminum compounds, includes a step of isolating independent olefin products and a step of treating catalyst residues. Further, the method includes the following sequential steps: a) isolating at least one liquid product of the oligomerization reaction of olefins from an output stream of an oligomerization reactor; b) treating a residue with an aqueous solution of an acid; and c) separating an organic layer and an aqueous layer.

  • Patent number: 8673312
    Abstract: Helicobacter pylori is closely associated with chronic gastritis, peptic ulcer disease, and gastric adenocarcinoma. Helicobacter pylori neutrophil-activating protein (HP-NAP), a virulence factor of Helicobacter pylori, plays an important role in pathogenesis of Helicobacter pylori infection. Since HP-NAP has been proposed as a candidate vaccine against Helicobacter pylori infection, an efficient way to obtain pure HP-NAP needs to be developed. In the present invention, recombinant HP-NAP expressed in Bacillus subtilis and Escherichia coli was purified through a single step of DEAE SEPHADEX ion-exchange chromatography with high purity. Also, purified recombinant HP-NAP was able to stimulate neutrophils to produce reactive oxygen species. Thus, recombinant HP-NAP obtained from our Bacillus subtilis expression system and Escherichia coli expression system is functionally active.

  • Patent number: 8598402
    Abstract: The present invention describes a n-butane absorption process for purifying the ethylene product from an ethane oxidation process. The ethane oxidation product is fed to a series of absorption towers using a n-butane solvent that remove the inert components as well as purifying the ethylene from the product. A first absorption tower uses n-butane as a solvent to absorb both the ethane and ethylene, allowing for inert gasses to be removed from the stream. An ethylene-rich side stream from this tower is sent to an ethylene purification tower where ethylene is purified using n-butane solvent. The bottom stream from the first absorption tower is then sent to an intermediate ethylene recovery tower where crude ethylene is purified, and the overhead ethylene stream being sent to the ethylene purification tower.
