Abstract: A method for direct methane (CH4) oxidation (DMTM) to methanol (CH3OH) includes passing an oxygen-containing feed gas stream into a reactor containing a copper-loaded mordenite zeolite (Cu-MOR) catalyst particles such that the oxygen-containing feed gas stream is in contact with the Cu-MOR catalyst particles, at a temperature of 100 to 500° C., to form an oxidized Cu-MOR catalyst. The method further includes displacing oxygen in the reactor by nitrogen purging, and further passing a CH4-containing feed gas stream through the reactor in contact with the oxidized Cu-MOR catalyst at a temperature of 50 to 200° C., thereby converting at least a portion of the CH4 to CH3OH. The method further includes regenerating the Cu-MOR catalyst particles to form a regenerated Cu-MOR catalyst. The CH3OH is adsorbed on surfaces and pores of the regenerated Cu-MOR catalyst.

Abstract: A method of utilizing humic acid to prepare layered humic acid/manganese oxide composite catalyst and its application, the method includes the steps of: adding sodium hypochlorite, manganese salt and humic acid to a water source, stirring and mixing; then introducing into a filter device having a filter material of manganese and a support medium, and generating a layered humic acid/manganese oxide composite catalyst on a surface of the filter material while directing a continuous water flow of the water source into the filter device with a short empty bed contact time for a short time. The catalyst can be used to effectively remove manganese to maintain an effluent with a Mn2+ concentration of not more than 20 μg/L and to effectively remove heavy metals such as iron, manganese, arsenic, thallium, molybdenum or lead from the water source under neutral, acidic or alkaline conditions with a removal rate of 95% more.

Abstract: The present invention belongs to the field of new material technology and relates to a bismuth/bismuth titanate heterojunction hollow nanospheres and methods for preparing the same and applications thereof. The bismuth/bismuth titanate heterojunction hollow nanospheres is obtained by adding a bismuth salt and tetrabutyl titanate into an organic solvent, mixing evenly, adding an inorganic alkali solution to generate a precipitation, then sequentially adding an organic amine and an organic acid, performing a solvothermal treatment to obtain bismuth titanate hollow nanospheres, and then thermally reducing the bismuth titanate hollow nanospheres with a borohydride under an inert atmosphere. The bismuth/bismuth titanate heterojunction hollow nanospheres provided not only exhibit significant photocatalytic activity in degrading tetracycline hydrochloride but also enable a tighter binding of the metal to the photocatalytic material, thus offering superior structural stability.

Abstract: A method for hydrotreating and recycling waste lubricating oil, the method comprising the two steps of slurry bed pre-hydrotreatment and deep hydrotreatment, specifically as follows: mechanical impurities are removed from waste lubricating oil, and then the oil is subjected to flash distillation to separate free water and a portion of light hydrocarbons; a bottom product of the flash distillation column is mixed with hydrogen and a self-sulfurizing oil-soluble transition metal catalyst, and then enters a slurry bed reactor for pre-hydrotreatment; a liquid product obtained by performing separation on a reaction effluent is subjected to hydrocyclone separation and solvent washing to remove solid residue, and then a pre-treated lubricating oil component is obtained; said component is mixed with hydrogen and then enters a hydrofining reactor, an isomerization-dewaxing reactor, and a supplementary refining reactor, connected in series, for hydrotreatment; and the reaction products are separated to obtain high-quality naphtha, diesel oil and a lubricating base oil. The method of the present invention has such advantages as simple processing procedures, a high oil liquid yield, good lubricating oil base oil quality, and can implement full-fraction resource utilization of waste lubricating oil. In addition, the oil-soluble catalyst features simple dispersion, no need for vulcanization, a small catalyst adding amount, high low-temperature hydrogenation activity, is capable of effectively preventing the coking that could occur during a process of preheating the waste lubricating oil, and ensures long-term stable operation of the device.
