  • Heterogeneous catalysis solid base catalyst and a preparation process and a use thereof
    Publication number: 20070232824
    Abstract: The present invention relates to a solid base catalyst including 10.0%-30.0% by weight of calcium oxide and 70.0%-90.0% by weight of zirconium oxide, in which the calcium source is CaCl2 or Ca(NO3)2, and the Zirconium source is ZrOCl2 or ZrO(NO3)2. The invention also provides a process for the preparation of the catalyst and a use of the catalyst in synthesizing dimethyl carbonate via heterogeneous catalysis. The catalyst shows good catalytic stability and catalytic activity, and can be separated from products easily and is reusable.

  • Methods for performing DAF data filtering and padding
    Patent number: 7272265
    Abstract: A method for padding, filtering, denoising, image enhancing and increased time-frequency acquisition is described for digitized data of a data set is described where unknown data is estimated using real data by adding unknown data points in a manner that the padding routine can estimate the interior data set including known and unknown data to a given accuracy on the known data points. The method also provides filtering using non-interpolating, well-tempered distributed approximating functional (NIDAF)-low-band-pass filters. The method also provides for symmetric and/or anti-symmetric extension of the data set so that the data set may be better refined and can be filtered by Fourier and other type of low frequency or harmonic filters.
