  • Publication number: 20150144842
    Abstract: A technology for producing synthesis gas from crude gas from various gasification processes for solid or liquid fuels. To limit the temperatures in a subsequent strongly exothermic CO shift reaction to adjust the H2/CO ratio, the crude gas which has been freed of dust flows through two shift reactors arranged in series. The first reactor has a specific reaction-kinetically limited catalyst and the second reactor has a conventional sour gas catalyst. The specific catalyst used in the first reactor limits the exothermic shift reaction to such an extent that the reaction temperatures in the first and second reactors remain so low to avoid thermal damage to the catalysts even without introduction of external steam, and the desired gas composition is achieved.

The dual-bed catalytic distillation tower has the advantage of flexible set up depending on various feeds, such as anhydrous or crude methanol and on different grades of DME to be obtained.

  • Patent number: 8420703
    Abstract: The purpose of the present invention is to provide a method for collecting effective components from polyester fiber waste containing polyalkylene telephthalate as the main component, more specifically to provide a method for separating and removing foreign matters (mainly cotton) contained in polyester fiber waste. The purpose of the invention can be achieved by a method for separating and removing foreign matters from polyester waste, which includes throwing polyester fiber waste that contains polyalkylene telephthalate as the main component and foreign matters other than the polyalkylene telephthalate into a depolymerization reaction tank, subjecting a part or all of the polyester fiber to a depolymerization reaction with alkylene glycol to give a depolymerization reaction liquid, and then continuously or intermittently feeding the liquid to a foreign matter-separating and removing apparatus having specified characteristics.

  • Patent number: 8309041
    Abstract: Systems for hydrocracking a heavy oil feedstock employ a colloidally or molecularly dispersed catalyst (e.g., molybdenum sulfide) which provide for concentration of the colloidally dispersed catalyst within the lower quality materials requiring additional hydrocracking. In addition to increased catalyst concentration, the inventive systems and methods provide increased reactor throughput, increased reaction rate, and of course higher conversion of asphaltenes and lower quality materials. Increased conversion levels of asphaltenes and lower quality materials also reduces equipment fouling, enables the reactor to process a wider range of lower quality feedstocks, and can lead to more efficient use of a supported catalyst if used in combination with the colloidal or molecular catalyst.
