Latest Patents

Among his latest patents, Shiroto has developed a detailed process for producing liquid hydrocarbon oil or dimethyl ether from a gas feed that includes lower hydrocarbons and carbon dioxide. His innovative method involves mixing the gas feed with water to create a mixed gas with specific ratios of carbon dioxide, water, and lower hydrocarbons. This mixed gas is then contacted with a Rhodium and Ruthenium on magnesium oxide catalyst, characterized by a specific surface area of 5 m²/g or less. This process achieves a carbon conversion efficiency of at least 50%. Furthermore, the synthesis gas generated exhibits a H2/CO molar ratio conducive for reaction with a Fischer-Tropsch catalyst to yield liquid hydrocarbon oil. Meanwhile, a different synthesis gas ratio is employed to produce dimethyl ether using various catalysts known for methanol synthesis, dehydrating, and carbon monoxide shift reactions.
