  • Publication number: 20100280261
    Abstract: The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors are germanium doped and comprise a precursor alumina blend. It has now surprisingly been discovered that inclusion of germanium, alone or in combination with such a blend, in porous body precursors can provide control over, or improvements to, surface morphology, physical properties, and/or surface chemistry of shaped porous bodies based thereupon. Surprisingly and advantageously, heat treating the shaped porous bodies can result in additional morphological changes so that additional fine tuning of the shaped porous bodies is possible in subsequent steps.

  • Patent number: 7825285
    Abstract: A process and an apparatus for the separation of a homogeneous catalyst solution from crude monoethylene glycol (MEG) and for purifying MEG is disclosed. The process comprises separating catalyst solution by evaporating crude MEG and feeding crude MEG to a rectification section, a stripping section, and thence to a pasteurisation section, each section operated at subatmospheric pressure of 0.5×105 Nm?2 or less, the rectification and pasteurisation sections being at pressure less than that of the catalyst separation section, wherein the process provides a pressure differential across the catalyst separation and rectification sections and wherein vapour phase crude MEG from the catalyst separation section is fed as substantially vapour phase feed to the rectification section.

  • Publication number: 20100176355
    Abstract: This invention publishes new usages of kinds of carbonic ester compounds. The new usage described in this invention is related to the application of carbonic ester compounds in the preparation of solvents for chemiluminescent systems. This invention also provides luminescent compositions, luminescent liquids and oxidized liquids that contain carbonic ester compounds. Chemiluminescent compositions containing carbonic ester compounds can decrease reaction pressure effectively, facilitate reaction balance heading to luminescence reaction, generate larger luminescent output without adding catalyst, decrease the dosage of catalyst or not need adding catalyst, decrease influences of over-high output at the reaction start caused by catalyst on whole luminescent time, and ensure stable light output from luminescent compositions. Carbonic ester compounds, especially long carbon chain carbonic ester, have the characters of non-toxic and high flash point, and have suitable solubility on ordinary bis oxalate ester.
