Abstract: A wall-flow type particulate filter includes: a wall-flow type base material; and a coat layer formed on the base material. The base material includes: an inlet cell open only at an exhaust gas inlet end; an outlet cell open only at an exhaust gas outlet end; and a partition partitioning the inlet and outlet cells and having multiple pores through which the inlet and outlet cells communicate with each other. The coat layer is provided for the wall surfaces of the pores and contains a first inorganic oxide and a second inorganic oxide. The mean particle diameter Da of the first inorganic oxide is larger than the mean particle diameter Db of the second inorganic oxide. The weight ratio of the second inorganic oxide is designed to be from 10% to 50% inclusive when the total weight ratio of the first inorganic oxide and the second inorganic oxide is 100%.

Abstract: The present invention provides a catalyst for catalytic reduction of an industrial flue gas SO2 with CO to prepare sulfur, a method for preparing the same and use thereof. A CeO2 nanocarrier is prepared by using a hydrothermal method, La and Y are loaded as active components, pre-sulfurization is conducted with 6% of SO2 and 3% of CO, and finally, the catalyst is prepared. The catalyst has high reactivity and sulfur selectivity and strong stability. The by-product sulfur generated by the reaction is recovered with a solvent CS2, and the solvent CS2 is recovered by using a distillation process. The preparation method is low in cost, causes no secondary pollution and is high in sulfur recovery rate. The problem of low sulfur production in China at present is solved.

Abstract: Described herein are catalysts and methods for converting waste biogas (e.g., a mixture of carbon dioxide and methane) into useful products. In some embodiments, the biogas is converted into a highly purified methane, that can be further processed to generate fuel products, including recycled natural gas (RNG) and liquid fuels. The described catalysts and methods may be advantageous over conventional methods, including by reducing catalyst costs, decreasing temperature requirements and/or providing higher purity products by reducing carbon dioxide and carbon monoxide in product streams.
