Latest Patents

Zhongjin Yi holds a patent for a method and system for the treatment of spent chloroaluminate ionic liquid catalyst and alkaline wastewater. This patent outlines a comprehensive process that includes several key steps. First, the catalyst is mixed with a concentrated brine for hydrolysis reaction until the residual activity of the catalyst is completely eliminated, resulting in an acidic hydrolysate and an acid-soluble oil. Next, the acidic hydrolysate is combined with an alkaline solution containing the alkaline wastewater for a neutralization reaction, producing a neutralization solution. The neutralization solution is then fully mixed with a flocculant, followed by sedimentation and separation. This process allows for the collection of concentrated brine for reuse in the hydrolysis reaction and concentrated flocs for further processing. The concentrated flocs are dehydrated to obtain concentrated brine and a wet solid slag, which is subsequently dried to yield a dry solid slag.
