Inventor: ZHILOU LIU
IPC: B01J23/755
Filed: 2020-11-09
Abstract: The disclosure provides a method for preparing a mercury (Hg) removal catalyst from a cathode scrap material, including the following steps: step (1): dealuminating a cathode scrap material to obtain a dealuminated cathode material; step (2): heat treating the dealuminated cathode material obtained in step (1) in the presence of an inert gas to obtain a metal oxide/carbon composite catalyst; step (3): grinding the metal oxide/carbon composite catalyst obtained in step (2), heating and activating in a reducing gas, and cooling to obtain a mercury removal catalyst. The disclosure also provides use of the above mercury removal catalyst. The disclosure uses a scrap ternary cathode material as a raw material to prepare a mercury removal catalyst, which turns a scrap material into a useful material, achieving resource recycling. Moreover, the disclosure has a low cost of raw material for preparing the mercury removal catalyst and a high economic value. The catalyst of the disclosure is highly efficient in Hg removal with a catalytic oxidation efficiency reaching more than 90%, which can significantly improve economic benefits.

Patent NL-7712792-A (NL)
IPC: G10L15/02
Filed: 1977-11-21
Abstract: A speech recognition system is realized by applying a speech signal to a feature extractor wherein a sequence of predetermined features representing the speech signal are determined, and by comparing the determined features, in an acceptor, to predetermined sequences of features which represent selected words. One attribute of the feature extractor is the ability to represent certain classes of sounds in terms of the position and direction of motion of the movable structures of a human vocal tract model, such as the position and direction of movement of the speaker's tongue body. The tongue body position is derived by determining the formant frequencies in the applied speech signal and by employing the Coker vocal tract model to find the tongue body position which best matches the determined formants.
