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: 8388902
    Abstract: A method for regenerating activated coke used for treating wastewater or sewage is provided. The method includes loading the activated coke to an environment under 150 to 250° C., heating the activated coke to a temperature of 700 to 850° C. for about 40 to 90 minutes; and providing a steam to the activated coke with a rate of 0.1 to 0.5 m3/(ton of activated coke). When the activated coke is being heated at the temperature, it generates a gas mixture including a steam portion and at least a paraffine gas. The gas mixture flows along a reverse direction relative to a flow of cooling water, so that the steam portion is converted into a part of the cooling water for recycling. The paraffine gas is used as a fuel. An apparatus for regenerating the activated coke used for treating wastewater or sewage is also provided.

    Abstract: Processes and apparatuses for regenerating catalyst particles are provided. The processes include introducing spent catalyst particles to a burn zone in a continuous catalyst regenerator. When introduced, the catalyst particles, which contain a platinum group metal, carry coke deposits. In the process, a combustion gas at a temperature of at least 490° C. with an oxygen content of at least 0.5 mol % is fed to the burn zone. There, the coke deposits on the catalyst particles are combusted with the combustion gas. The catalyst particles are passed from the burn zone to a halogenation zone in the continuous catalyst regenerator and the catalyst particles are oxyhalogenated to redisperse the platinum group metal to form regenerated catalyst particles.

  • Patent number: 8263014
    Abstract: In an apparatus and method of generating a carbon nanotube (CNT), a process chamber is heated to a target temperature and a catalyst powder is supplied into the heated process chamber. The catalyst powder moves in a first direction in the process chamber. A source gas is supplied into the process chamber in a second direction opposite to the first direction, so that the source gas delays the movement of the catalyst powder in the first direction and is reacted with the catalyst powder in the process chamber to thereby produce the CNT in the process chamber. Accordingly, the flow of the source gas against the flow of the catalyst powder reduces the drop velocity of the catalyst powder. Therefore, the source gas and the catalyst powder may be reacted with each other for a sufficiently long time.
