  • Patent number: 11279667
    Abstract: The present invention relates to a novel process for oxidative esterification, generally for reaction of aldehydes with alcohols in the presence of oxygenous gases directly to give the corresponding ester in the presence of a heterogeneous catalyst, by means of which, for example, (meth)acrolein can be converted to methyl (meth)acrylate. The new catalyst has titanium dioxide as the main component of the support material. The catalysts are especially notable for high mechanical and chemical stability and for good catalytic performance even over very long periods. The process is an improvement in the catalyst service life, activity and selectivity over prior art catalysts which lose activity and/or selectivity relatively quickly in continuous operation in media having even a small water content.

    Abstract: A manufacturing system and method for recycling and smelting crushed silica from silicon plants, including a crushed silica storage device, granulator, submerged arc furnace, transfer device, forming device and cooling system. Firstly silicon waste is collected, then crushed silica is output to a granulator. The granulator mixes the waste irregular crushed silica with water, and granulates and produces small particles having an uniform grain size as the raw material for smelting. The raw material is smelted in the submerged arc furnace. The forming device evenly pours the silicon liquid into the cooling system according to a set flow rate. The silicon liquid is solidified to form silicon pellets, and then a lift system is used to lift the formed silicon pellets, wherein the silicon liquid poured into the cooling system has a uniform diameter. The system can rapidly and efficiently smelt the silicon waste from the silicon plants.
