Latest Patents

One of Shenjun Dai's latest patents involves a preparation method for a supported catalyst Mo-O-K-MeO for the synthesis of methanethiol from HS-containing syngas. This innovative catalyst comprises an active component of Mo-O-K-based species, an active promoter, and a support denoted as metal (or metals)-carrier. The support is prepared using an electroless plating method, where selected metals are plated onto the surface of the carrier. Transition metals such as Fe, Co, or Ni are chosen for plating, while SiO, AlO, or TiO serve as carriers. The resulting catalyst demonstrates high efficiency in synthesizing methanethiol, particularly with minimal formation of the by-product CO. Another significant patent describes a continuous process for manufacturing methyl mercaptan using Mo-O-K-based catalysts, highlighting that total selectivity can be increased by lowering the total gas hourly space velocity.
