His innovative processes have implications for various industries, including materials science and energy.

Latest Patents

Oshiguri holds a patent for a process of producing carbonaceous pitch. This continuous process involves heat-treating an aromatic heavy oil to obtain a first cracked product. The first product is then thermally cracked in a cracking zone by direct contact with a gaseous heat transfer medium. This method yields distillable cracked components and a mesophase-containing pitch. A portion of the liquid phase in the cracking zone is separated into a mesophase-rich pitch and a matrix pitch with a low concentration of mesophase. The mesophase-rich pitch is recovered, while some of the matrix pitch is recycled back to the cracking zone. The distillable cracked components are withdrawn and separated into light, middle, and heavy fractions. Additionally, a portion of the heavy fraction is heat-treated and recycled, while the middle and/or heavy fractions are hydrotreated to produce a hydrogen-donating oil. This oil is then reacted with a second portion of the liquid phase to hydrogenate the mesophase contained therein, with the reaction product being recycled to the cracking zone. Noriaki Oshiguri has 1 patent to his name.
