Abstract: The present invention relates to the technical field of rubber materials, and discloses a functional modification of reclaimed rubber material and use thereof in making safety gloves, wherein by using the hyperbranched nitrile butadiene rubber-polyurethane as the filling and modification agent, mixing with the nitrile butadiene rubber and reclaimed nitrile butadiene rubber for modification, the hyperbranched polyurethane has three dimensional branched network structures, in the meanwhile, nitrile butadiene rubber molecular chains are contained in the main chains, so that the hyperbranched nitrile butadiene rubber-polyurethane, the nitrile butadiene rubber and the reclaimed nitrile butadiene rubber have good interface compatibility, and the hyperbranched nitrile butadiene rubber-polyurethane, the nitrile butadiene rubber and the reclaimed nitrile butadiene rubber form three-dimensional interlinking networks, so that the mechanical properties such as tensile strength and tear strength of the reclaimed rubber co

Abstract: A catalyst system for purifying an exhaust gas, comprising one or more antimony-containing regions comprising an antimony-containing catalyst, particularly antimony-containing SCR catalyst, and one or more antimony-trapping regions comprising a molecular sieve which is optionally metal-promoted, wherein at least one of the antimony-trapping regions is located downstream of the one or more antimony-containing regions in a flow direction of the exhaust gas, and also a method for treatment of an exhaust gas containing nitrogen oxides.

Abstract: The present invention relates to a catalytic article for purifying an exhaust gas containing nitrogen oxides, which comprises a first region containing a vanadium-based SCR catalyst, a second region containing a metal-promoted molecular sieve catalyst, and a third region containing a vanadium-based SCR catalyst, wherein at least part of the second region is located downstream of at least part of the first region and upstream of at least part of the third region in the exhaust gas flow direction, provided that no part of the second region is located upstream of the first region or downstream of the third region. The present invention also relates to a method and a system for treatment of an exhaust gas containing nitrogen oxides by selective catalytic reduction using the catalytic article.
