Abstract: A gas nozzle (100), a gas reaction device (10) and a gas hydrolysis reaction method. A plurality of fuel gas channels (116) are provided on a side wall of a nozzle cavity (110) of the gas nozzle (100); the plurality of fuel gas channels (116) are arranged around the side wall of the nozzle cavity (110); a mixed gas introduced from a nozzle inlet (112) is surrounded by a fuel gas (21) introduced from the plurality of fuel gas channels (116); and the fuel gas channels (116) are inclined towards a nozzle outlet (114), and the fuel gas channels (116) are further inclined in the same clockwise direction. In this way, the fuel gas (21) introduced from the plurality of fuel gas channels (116) forms a downwardly conical spiral flame, and a flame formed by the mixed gas introduced from the nozzle inlet (112) is wrapped therein and sprayed out from the nozzle outlet (114).

Abstract: Methods of converting a variety of fluorinated materials into anhydrous hydrogen fluoride are described. The methods include thermally decomposing the fluorinated materials into a gaseous effluent comprising hydrogen fluoride and carbon dioxide. This gaseous effluent is then treated with carbon at a temperature of at least 830° C., converting the carbon dioxide to carbon monoxide (CO) and producing a gaseous product comprising the hydrogen fluoride, which can be condensed to generate anhydrous hydrogen fluoride. These methods can also be used to convert water contained in the gaseous effluent into hydrogen.

Abstract: A universal chemical processor (UCP) including a reactor vessel with a main chamber, comprises inlets for feedstock, a fluidizing medium and reactants. The UCP further includes a reactive X-ray chemical processor (RXCP) having a large area hollow cylindrical cold cathode in the main chamber, a grid positioned concentrically with respect to the cathode, and an anode positioned concentrically with respect to the cathode and grid. In operation, when activated, the cathode of the RXCP emits electrodes onto the anode, which then emits X-rays into a radiation zone within the main chamber capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing organic materials within the radiation zone, and wherein, a fluidized bed is supported in the main chamber when the fluidizing medium and feedstock are supplied. The RXCP and the fluidized bed portions can be operated separately or in conjunction to achieve unanticipated results.

Abstract: The present invention provides a novel method for producing hydrogen fluoride which can suppress the occurrence of the pasty state over the whole process of producing hydrogen fluoride, reduce the problem of corrosion caused by sulfuric acid, and improve energy efficiency of the process. A method for producing hydrogen fluoride by reacting calcium fluoride and sulfuric acid comprises: (a) mixing and reacting calcium fluoride and sulfuric acid such that a mixture comprising calcium fluoride particles and sulfuric acid substantially maintains a form of particulate to obtain hydrogen fluoride while supplying sulfuric acid to the calcium fluoride particles at a flow rate of 0.002 to 1 mol/min relative to 1 mol of calcium fluoride to such an amount that a molar ratio of sulfuric acid/calcium fluoride is 0.9 to 1.1.
