A classifying fluid bed granulation unit includes a perforated bed floor; a fluid bed section; a solid feed inlet or internal crushing device; a fluidization air inlet; a liquid solution or melt feed inlet and nozzles; an air outlet; and a product outlet; wherein the fluid bed section comprises at least one particle classification element comprising one or more vertically inclined channels having top and bottom end feed openings, and wherein the one or more vertically inclined channels have upper and lower side slots. In operation of the above fluid bed granulation unit, each channel of the element is separating particles into large particle and small particle fractions and transporting the large particle fraction upwards and the small particle fraction downwards in each channel, and the large particle and small particle fractions are transported out of the upper and lower side slots, respectively.

The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt % to 30 wt %, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.

A method of manufacturing lithium-metal nitride including suspending a lithium-metal-oxide-powder (LMOP) within a gaseous mixture, incrementally heating the suspended LMOP to a holding temperature of between 400 and 800 degrees Celsius such that the LMOP reaches the holding temperature, and maintaining the LMOP at the holding temperature for a time period in order for the gaseous mixture and the LMOP to react to form a lithium-metal nitride powder (LMNP).

A system for watering an electrolyte or lead acid battery in which the cumulative amount of water added during each filling event is determined by detecting the amount of water passing from a supply hose to the battery. A fluid dispensing member, such as a direct fill link or nozzle, can be attached to and detached from a single point watering subsystem. A flow detector, such as a flow meter, in fluid communication with the fluid dispensing member can wirelessly output the cumulative water added to specific batteries to an interactive computer application, which can include a wireless component such as a smartphone or tablet communicating with a remotely located interactive database.

Retro-aldol processes are disclosed that use very low concentrations of retro-aldol catalyst in combination with hydrogenation catalyst of certain activities, sizes and spatial dispersions to obtain the high selectivities to ethylene glycol.

A method is disclosed in which a gas of hydrogen and nitrogen, or hydrogen and ammonia, or hydrogen, nitrogen, and ammonia, is introduced to a fluidized bed. The gas flows through the fluidized bed, and titanium dioxide particles are introduced to the fluidized bed to form a fluid mixture of the particles and gas in the fluidized bed. The particles are reacted with the gas in the fluid mixture to form particles including titanium dioxide and nitrogen. The particles can be disposed along an air flow path in operative communication with a light source for air treatment.
