Latest Patents

One of Yu's latest patents is a method for preparing ammonia by using ammonium salt and silicate. This method involves a reaction between an aqueous solution of ammonium salt, in the form of atomized droplets, and silicate at high temperatures to generate ammonia gas and a solid substance. The silicate can be solid particles that form a bed, allowing for the collection of generated ammonia gas while extracting the solid substance. Additionally, part of the solid substance is mixed with fresh silicate solid particles, enabling continuous reactions with the atomized droplets of the ammonium salt solution. Another significant patent is the preparation device and method for ammonia gas. This device utilizes a fluidized bed reactor with at least two fluidization chambers, including a preheating chamber and a reaction chamber equipped with atomizing nozzles. The particulate inorganic salt forms a fluidized bed layer and reacts with an aqueous solution of ammonium chloride to produce ammonia gas.
