摘要： The present invention provides a process for preparing a catalytic cracking catalyst, which is characterized in that the process comprises: mixing raw materials including a rare earth-containing NaY molecular sieve obtained by contacting a NaY molecular sieve with a rare-earth salt solution or a mixed solution of rare-earth salt solution and ammonium salt solution, filtering, and water-washing, an inorganic oxide binder and a natural mineral, slurrying and shaping into shaped bodies; hydrothermally calcining shaped bodies in an atmosphere condition where a pressure is externally applied and an aqueous solution containing an acidic substance or an alkaline substance is extennally added; and then ammonium-exchanging to remove the alkali metal. The present invention optimizes and shortens the preparation process of the catalyst, which can reduce the preparation cost, and the prepared catalyst has excellent heavy oil conversion ability, higher gasoline and diesel yield, lower coke selectivity, and relatively reduces the used amount of the molecular sieve in the catalyst.

摘要： Provided in the embodiments of the present invention are a wind power generation apparatus and method. The wind power generation apparatus comprises an acquisition unit, a wind turbine, a generator, an electric power storage unit and a controller, wherein the acquisition unit is used for acquiring a wind power value; the controller is used for selecting, according to the wind power value, the wind turbine to drive the generator to generate power and/or the wind turbine to drive the electric power storage unit to charge, comprising: if the wind power value is between a first wind power threshold value and a second wind power threshold value, the wind turbine only drives the generator to generate power; if the wind power value is greater than the second wind power threshold value, the wind turbine simultaneously drives the generator and the electric power storage unit to charge; and if the wind power value is less than the first wind power threshold value, the wind turbine only drives the electric power storage unit to charge or drives the electric power storage unit to output induced electric energy to the outside, wherein the first wind power threshold value is less than the second wind power threshold value. The wind power generation apparatus can effectively convert wind energy into electric energy, thereby improving the output and stability of a wind generating set.

摘要： The present invention provides an electrolysis device, electrolysis system, and electrolysis method for alternating current induction power supply. The electrolysis device comprises: at least one group of magnetic circuits and an electrolytic cell, wherein the magnetic circuits comprise a magnetic core on which an electromagnetic coil is wound, the magnetic core being provided outside the electrolytic cell; and the magnetic circuits are used for using an alternating current power source to generate a rotating magnetic field surrounding the electrolytic cell, the rotating magnetic field acting on an electrolyte in the electrolytic cell to generate an induction direct current, such that the electrolyte is electrolyzed. According to the electrolysis device, the electrolytic cell generates the induction direct current directly by means of an alternating current, such that alternating current and direct current conversion links are reduced, and energy loss caused by energy conversion is reduced.
