Latest Patents

Seiji Togawa holds a patent for a "Method of producing middle distillate products by two-stage hydrocracking and hydrocracking apparatus." This patent describes a two-stage hydrocracking process that involves bringing the first-stage feed oil, which contains a hydrocarbon component with a boiling point of 316°C or higher, into contact with a first-stage catalyst in the presence of hydrogen. The process yields a first-stage product that is then separated into heavy and light components, with the light component containing the desired middle distillate products. The second-stage feed oil, which consists of the heavy component from the first-stage reaction product, is treated with a second-stage catalyst to obtain a second-stage product. This product is also separated into heavy and light components, with part of the heavy component being recycled back to the second-stage feed oil. The hydrocracking activity of the first-stage catalyst is notably higher than that of the second-stage catalyst.
