Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading and reactor pressure drop. More particularly, a scale collection device is in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.

The present disclosure provides a method for preparing a transition metal lithium oxide, comprising steps of: A) mixing a lithium salt and a transition metal compound, and performing a pretreatment to obtain a precursor; wherein the pretreatment temperature is 100-300° C.; and the pretreatment time is 1-10 h; B) precalcining the precursor to obtain an intermediate; and C) continuously feeding the intermediate into a feed port of a moving bed reactor, and calcining, to obtain a transition metal lithium oxide. In the present disclosure, a pretreatment process is performed before the precalcination, and the pretreatment temperature and time are further limited, thereby solving the problem of material hardening during the calcination process of battery materials. In conjunction with using a moving bed reactor, the gas phase and the solid phase are sufficiently contacted, and at the same time the thickness of the filler is increased, the productivity is enhanced and the oxygen consumption is largely decreased at the same time. The present disclosure further provides an apparatus for preparing a transition metal lithium oxide.

An apparatus for the production of solid dosage forms is presented, wherein the apparatus comprises a material processing chamber which is operable for manufacturing a product according to a pre-set product formation process path. The apparatus has at least one sensor for continuously monitoring formation of the product in the material processing chamber during the product formation process non-invasively in real time by sensing at least one product functional attribute value and a means for comparing each sensed product functional attribute value with a desirable product functional attribute value for that point on the product formation process path. A controller controls operation of the material processing chamber in response to the sensed product functional attribute value for maintaining the product on the product formation process path.

A process for catalytic cracking of hydrocarbon oils includes the step of contacting a hydrocarbon oil feedstock with a catalytic cracking catalyst in a reactor comprising a dilute-phase transport fluidized bed and a fast fluidized bed connected in series for reaction. In the fast fluidized bed, the axial solid fraction c of the catalyst is controlled within the range of about 0.1 to about 0.2. When used for catalytic cracking of hydrocarbon oil feedstocks, particularly heavy feedstock oils, the process and system show lower yields of dry gas and coke, and good product distribution.
