摘要： The present invention relates to a method for production of ammonia, using an inorganic nanoparticle-microbial complex in which a nitrogen fixation reaction in a microorganism is improved by increasing the amount of inorganic nanoparticles entrapped in the microorganism. The present invention can produce ammonia at low temperature and low pressure conditions, compared to the conventional Haber-Bosch process of producing ammonia in high temperature and high pressure conditions and in a friendly environmental manner without emission of carbon dioxide that is released during conventional chemical synthesis processes, whereby the present invention may be a competitive alternative to the prior art for production of ammonia that has an unlimited potential as a future energy resource.

摘要： A process of producing a catalyst comprises forming mesoporous beta zeolite particles, impregnating mesoporous beta zeolite particles with a metal and phosphorus to produce a metal and phosphorus impregnated zeolite, and incorporating the metal and phosphorus impregnated zeolite with clay and alumina to produce the catalyst. The forming step comprises converting a crystalline beta zeolite to a non-crystalline material with reduced silica content relative to the crystalline beta zeolite, and crystalizing the non-crystalline material to produce mesoporous beta zeolite particles.

摘要： Carbon-doped graphitic carbon nitride (g-C3N4) compositions are synthesized from the chemical precursors melamine, cyanuric acid and barbituric acid. Phosphorus-doped g-C3N4 compositions are synthesized from the chemical precursors melamine, cyanuric acid and etidronic acid. Carbon- and phosphorus-doped g-C3N4 compositions, when in the presence of UV or visible light, can be used in water treatment systems to photocatalytically degrade persistent organic micropollutants such as pharmaceuticals and personal care products (PPCPs), endocrine disrupting compounds (EDCs), pesticides, and herbicides. Carbon- and phosphorus-doped g-C3N4 compositions can also be applied to surfaces of household and public items to kill protozoa, eukaryotic parasites, algal pathogens, bacteria, fungi, prions, viruses, or other microorganisms, preventing the transfer thereof between users.

摘要： The solar-powered oxygen production system for hospitals is useful for producing oxygen in hospital settings without the need for an external power source. The system includes one or more photovoltaic (PV) solar panels mounted on the roof of a hospital and an oxygen production system housed within the equipment room of the hospital. The solar panels provide the electrical power needed for the oxygen production system. The solar panels are mounted on the roof using solar panel supports. The number of panels and the power output of each panel can be selected depending on the electrical power requirements of the oxygen production system. The oxygen production system includes an LED for activating a black phosphorous catalyst in the atmospheric air to convert water vapor in the air into hydrogen and oxygen.

摘要： A process for preparing aldehydes by a homogeneously catalysed hydroformylation of C4 to C20 olefins involves withdrawing a biphasic stream (liquid/gaseous) and expanding in two stages. Before, between, or after the two stages, the liquid phase is cooled. Only after expansion and cooling is the homogeneously dissolved rhodium catalyst system separated from the residual stream.

摘要： Systems and methods are provided for modifying the composition of the conversion catalyst in a reactor for oxygenate conversion during conversion of an oxygenate feed to allow for adjustment of the slate of conversion products. The modification of the conversion catalyst can be performed by introducing a substantial portion (relative to the amount of catalyst inventory in the reaction system) of make-up catalyst having a distinct composition relative to the conversion catalyst in the reaction system. Introducing the distinct composition of make-up catalyst can modify the composition of the conversion catalyst in the reactor to allow for changes in the resulting product slate. By introducing the distinct catalyst composition, the conversion catalyst in the reactor can correspond to a different composition of catalyst than the overall average catalyst composition within the catalyst inventory in the reaction system.
