Title: Innovations of Hongbin Xu in Chromate Production
Introduction
Hongbin Xu is a notable inventor based in Beijing, China. He has made significant contributions to the field of chemical engineering, particularly in the production of alkali metal chromates. His innovative methods have the potential to enhance the efficiency and environmental sustainability of chromate production.
Latest Patents
Hongbin Xu holds a patent for a method for the production of alkali metal chromates. This invention relates to a method that involves several steps, including the obtaining of a mixture of alkali metal hydroxide, alkali metal chromate, and ferrous residue after the reaction of chromite ore with an oxidant. The process is conducted in the presence of molten salt or in an aqueous solution of alkali metal hydroxide. The method results in a leaching slurry, from which the primary chromate product is separated. The pure chromate crystal is then obtained by purifying the primary chromate product. This innovative method offers several advantages over the currently-used roasting method, such as a reduction in reaction temperature by about 700°C, an improved chromium recovery rate of nearly 100%, and the minimization of ferrous residue. Additionally, it eliminates the disposal problem of chromium-containing residue and reduces environmental pollution.
Career Highlights
