摘要： Disclosed is a method for producing low carbon olefins and/or aromatics from feedstock comprising naphtha. The method can include the following steps: a) feeding feedstock comprising naphtha into a fast fluidized bed reactor; b) contacting the feedstock with a catalyst under conditions to produce a gas product and spent catalyst; c) separating the gas product to produce a stream comprising primarily one or more low carbon olefins and/or one or more aromatics; d) transporting the spent catalyst to a regenerator; e) regenerating the spent catalyst in the regenerator to form regenerated catalyst; and f) returning the regenerated catalyst to the fast fluidized bed reactor.

摘要： A zinc iodine flow battery includes a positive end plate, a positive current collector, a negative current collector, a positive electrode with a flow frame, a membrane, a negative electrode with a flow frame, a negative end plate. The negative electrolyte is circulated between the negative storage tank and the negative cavity by pump. The negative pipe is provided with a branch pipe for the positive electrolyte circulation. The porous membrane between the positive and negative electrodes can realize the conduction of supporting electrolyte and prevent the diffusion of I3− to the negative electrolyte. In a duel-flow battery system, same electrolyte serves as both the positive electrolyte and the negative electrolyte, which is a mixed aqueous solution containing iodized and zinc salt. The membrane is porous membrane does not contain ion exchange group. Both the positive and negative electrolyte are neutral solutions.

摘要： The neutral zinc manganese battery includes a neutral zinc manganese flow battery and a power battery. The flow battery includes positive electrode, negative electrode, electrolyte and membrane. The corresponding flow battery includes positive and negative pumps, pipelines and storage tanks. For the power battery, the electrolyte is stored in the porous electrode, while for the flow battery, the positive and negative electrolyte flows through the positive and negative electrodes through the pump and pipeline and finally returns to the storage tank to realize the circulation of electrolyte in the electrode chamber and storage tank. In addition, the positive and negative electrode electrolyte is a neutral solution of zinc salt and manganese salt with specific composition. During charging, MnO2 of the positive electrode can be oxidized directly to α-MnO2. During discharge, MnO2 dissolves into Mn2+.
