Latest Patents

One of Ishikawa's latest patents is the development of a multiple zeolite catalyst. This catalytic composition is designed to convert calkylaromatic hydrocarbons into BTX, particularly commercially valuable xylenes. The catalyst is created by mixing at least two zeolites selected from a variety of types, including mordenite, beta zeolite, ZSM-5, and others. Additionally, it incorporates at least one metal component from Group VIB and Group VIII of the Periodic Table. The unique combination of zeolites with different physical and chemical characteristics, such as pore size and acidity, enhances the catalyst's effectiveness. An exemplary formulation includes mordenite, ZSM-5, and 3 wt. % molybdenum. The transalkylation reaction can be conducted under specific conditions, including temperatures ranging from 200-540°C and pressures of 1.0-5.0 MPa.

Another notable patent involves low sulfur gas oil. This innovation pertains to gas oils derived from distilled petroleum fractions that undergo hydrogenating treatment under specific conditions. The resulting gas oils maintain a sulfur concentration of 350 ppm or below, making them more environmentally friendly.
