Abstract: A crop prediction system performs various machine learning operations to predict crop production and to identify a set of farming operations that, if performed, optimize crop production. The crop prediction system uses crop prediction models trained using various machine learning operations based on geographic and agronomic information. Responsive to receiving a request from a grower, the crop prediction system can access information representation of a portion of land corresponding to the request, such as the location of the land and corresponding weather conditions and soil composition. The crop prediction system applies one or more crop prediction models to the access information to predict a crop production and identify an optimized set of farming operations for the grower to perform.

Abstract: Provided is a process for converting biomass waste to a solid carbon product. The process comprises passing the biomass waste batchwise into a reactor comprising a twin screw conveyor. The reactor is heated at a temperature of, e.g., 300-450° C. to avoid cracking of the hydrocarbons in the biomass waste. The biomass waste is passed with heating and mixing along the length of the reactor, and a solid carbon product is collected from the reactor. The solid carbon products can be buried to provide a more permanent removal of the carbon.

Abstract: A process is hereby provided for permanently (>1000 years) reducing carbon dioxide in the atmosphere. The process involves the cultivation of tree and plant waste (biomass), the conversion of the biomass in a reactor to a carbon product, e.g., charcoal, and subsequent storage of the carbon product. The reactor used for conversion is run at a low temperature, e.g., 300-450° C. Thus, there is negligible cracking. The product is primarily a solid carbon product, which is safe and can be easily handled. The carbon product can also be safely stored. In one embodiment, the carbon product is buried in a location that is tested for limited oxygen at burial depths. The permanence of the CO2 reduction is therefore assured.

Abstract: Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include a zeolite with a low silica to alumina ratio combined with a low surface binder, or alternatively the formulated catalyst has a high ratio of zeolite surface area to external surface area.

Abstract: A spectrophone assembly comprises a single detector chamber, a plurality of lasers, a gas inlet for supplying a gas sample to the single detector chamber, and at least one microphone. The detector chamber has an internal geometry arranged to be simultaneously acoustically resonant at a plurality of different resonant frequencies. Each laser operates at a different wavelength and is positioned to emit radiation into the single detector chamber, and is operable to emit radiation that is amplitude modulated at a frequency rate corresponding to a particular resonant frequency different from the resonant frequency of each other laser, simultaneously with each other laser. The microphone(s) are positioned in the single detector chamber so that each microphone is located at or near a maximum of a corresponding acoustic resonance defined by the internal geometry of the detector chamber.

Abstract: A process is provided for the production of xylenes from reformate. The process is carried out by methylating the benzene, toluene, or both present in the reformate to produce a resulting product having a higher xylenes content than the reformate. Greater than equilibrium amounts of para-xylene can be produced by the process.

Abstract: An oligomerization process in which hydrocarbon feedstocks are contacted with a hydrotreating catalyst in the absence of hydrogen and in the liquid phase. The catalyst is a heterogeneous catalyst selected from supported reduced metals, metals oxides, metal sulfides and combinations thereof. Preferred catalysts include mixed nickel and molybdenum oxides or mixed cobalt and molybdenum oxides. The process also oligomerizes sulfur compounds so that sulfur containing feedstocks can be treated without deactivating the catalysts.

Abstract: In a process for synthesizing a crystalline molecular sieve, an aqueous synthesis mixture is produced capable of forming the crystalline molecular sieve. Crystallization of the synthesis mixture is induced so as to form crystals of said molecular sieve in the synthesis mixture and, when crystallization is complete, the molecular sieve crystals are allowed or caused to separate from the remainder of the synthesis mixture to produce a solid phase comprising said molecular sieve crystals and a supernatant liquid phase. The supernatant liquid phase is then decanted from the solid phase to recover the molecular sieve crystals and the crystals are dried without initially being subjected to washing or filtration.
