A heat transfer media comprises a particle. The particle comprises a discontinuous phase and a matrix material. The discontinuous phase is disposed within the matrix material, and the matrix material has a higher melting point than the discontinuous phase. The discontinuous phase has a melting point selected to be within a reaction temperature range.

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 to decompose a hydrocarbon reactant into a gaseous product and a solid product includes a reactor volume, a reservoir of liquid material, a plurality of nozzles connected to the reservoir of liquid material, the plurality of nozzles configured to distribute the liquid material into the reactor volume from the reservoir as a liquid mist, a gas inlet connected to a hydrocarbon gas source to receive hydrocarbon gas reactant, a distributor connected to the inlet to distribute the hydrocarbon gas reactant into the reactor volume, a heat source located adjacent the reactor volume configured to heat the reactor volume, a separator to separate the solid product from the liquid material, a re-circulation path connected between the reactor volume and the reservoir to re-circulate the liquid material from the reactor volume to the reservoir, a gas outlet connected to the reactor volume configured to outlet hydrogen gas from the reactor volume, and at least one filter connected to the gas outlet to remove entrained solid product from the hydrogen gas.

A method to decompose a hydrocarbon reactant into a gaseous product and a solid product includes generating a mist of a liquid material within a reactor volume, heating the reactor volume, introducing a hydrocarbon reactant into the reactor volume to produce a solid product and a gaseous product, separating the solid product from the liquid material, removing the solid product and gaseous product from the reactor volume, and recirculating the liquid material be re-introduced to the reactor volume.

Systems and methods are provided for conversion of oxygenate feeds to distillate boiling range products using multiple moving bed reactor stages. The systems and methods allow for multiple stages to be used while avoiding the need for distillation or other boiling point based separation as the mixture of feed and effluent is passed between stages. Instead, a stripping gas is used to disengage the feed and effluent from the catalyst solids. In combination with an improved moving bed reactor design, this can allow substantially all of the feed and effluent from a first moving bed reactor stage to be passed into a second moving bed reactor stage, even when the feed and effluent include both vapor and liquid phase portions.

A steam-assisted catalytic cracking process for a hydrocarbon feed is provided. The process includes: introducing the hydrocarbon feed, a fluid catalytic cracking (FCC) catalyst, and steam to a FCC reactor with a mass ratio of steam to hydrocarbon feed between 0.05 and 1.0; cracking the hydrocarbon feed in the presence of the FCC catalyst and steam to produce a cracked hydrocarbon feed and spent FCC catalyst, the spent FCC catalyst comprising coke deposits and hydrocarbon deposits; stripping the hydrocarbon deposits from the spent FCC catalyst with steam in a stripper to obtain a hydrocarbon-stripped spent FCC catalyst; regenerating the hydrocarbon-stripped spent FCC catalyst in a regenerator by subjecting the stripped spent FCC catalyst to heat in the presence of oxygen to combust the coke deposits on the stripped spent FCC catalyst and produce a regenerated FCC catalyst; recycling the regenerated FCC catalyst.
