Latest Patents

Sakurai's notable patent is titled "Method for continuous thermal cracking of heavy petroleum oil." This invention discloses an improved method designed to achieve a high degree of cracking in a relatively small, column-like reactor. The process is adept at providing residual pitch rich in beta-resin components while minimizing the gas mixture. The method involves charging preheated heavy oil into an upright cylindrical continuous reactor. This reactor is divided into upper and lower reaction zones by a partition plate. Cracked gas and oil vapor are drawn from the upper reaction zone, while residual pitch is discharged from the bottom of the lower reaction zone. Moreover, the patent includes enhancements such as a cooling chamber and a defoaming chamber to terminate reactions and subject the resulting pitch to defoaming. Additionally, the invention features a rotary scraper within the reactor, equipped with blades that are contiguous to the reactor walls or partition plates.
