Abstract: A reformed hydrocarbon and hydrogen are produced by: subjecting a raw hydrocarbon material to thermal catalytic cracking under hydrogen for dehydrogenation to produce a reformed hydrocarbon having a degree of unsaturation higher than that of the raw hydrocarbon material and hydrogen; introducing the reformed hydrocarbon, hydrogen and an unreacted hydrocarbon into a pressure-reducing-rising device; and reducing and then raising a pressure to facilitate further cracking of the unreacted hydrocarbon and promote liquid-gas separation in a post-step. Hydrogen can be efficiently produced, and a reformed hydrocarbon of good quality (e.g., high octane number) can be produced with suppressing generation of carbon.

Abstract: A method and apparatus of cooling incinerator exhaust gas for a cleaning treatment of high temperature exhaust gas discharged from an incinerator of refuse and/or waste in a post-step are provided. A spray cooling chamber includes a chamber having a lower end portion formed into a nearly cylindrical shape of an inverted conical shape, a gas distribution chamber equipped with a revolving blade, arranged at an upstream side of the chamber, a sprayer of a cooling liquid arranged at central upper portion of the chamber, a dust exhaust port arranged at the lower end portion of the chamber, and an exhaust pipe arranged on the chamber. Waste heat recovery from exhaust gas is limited to a temperature range capable of suppressing generation of dioxins, and high temperature exhaust gas is rapidly cooled, particularly at a temperature drop rate such that the vicinity of 300.degree. C. is dropped in a short time within 1 second, so that exhaust concentration of dioxins from an incinerator plant can be decreased to 0.

Abstract: A nozzle unit having a pressure nozzle for spraying feed liquid and a cylindrical outer tube disposed around the pressure nozzle for high-speed gas blowing. The tip of the nozzle unit is of converging construction. When water is sprayed at low pressure in the nozzle unit, water is atomized to fine droplets.

Abstract: The present invention provides a spray-drying granulation apparatus having a chamber comprising (a) an upper section which is a spray-drying section for spraying a feed solution from a nozzle and drying the formed droplets with hot air and (b) a lower section which is a fluidized granulation section, in which apparatus there is used, as the nozzle for spraying a feed solution, a two-fluid pressure nozzle comprising a centrifugal pressure nozzle for spraying a feed solution and a cylindrical pipe for blowing out a high-speed gas, provided around the centrifugal pressure nozzle. This spray-drying granulation apparatus enables spraying of even a feed solution of large volume with only one nozzle. Further with the two-fluid pressure nozzle of the apparatus, there is no need of replacement of nozzle parts when the feed rate, concentration, viscosity, kind, etc.

Abstract: In conventional fluidized granulators whose housing is made of a steel plate, a powder tends to cause blocking if it is highly hygroscopic, and the bag filter used therein causes clogging. These problems have been solved in the present invention by forming the housing of a fluidized granulator with a porous membrane in place of the conventional steel plate. This fluidized granulator produces granules or a coated powder by spraying powder with water, a binder fluid or a coating fluid while maintaining the powder in a fluidized state.

Abstract: A spray-drying granulation apparatus having: a spray drying section formed in an upper position of a chamber wherein sprayed feed liquid particles are dried to powder by a hot-air; and a powder granulation section formed in a power position of the chamber, and provided with a nozzle for feeding a binder liquid. There is no need of maintaining sticky powder or completely dried powder to the lower section. The sprayed particles can be dried to powder in a wide drying range before they are granulated in the granulation section by a binder liquid. The degree of granulation can be selected as desired while preventing attachment of powder to the inner wall of the chamber due to incomplete drying.

Abstract: Process for producing microcapsules. Wax or a mixture of wax and protein is dissolved in a mixed solvent consisting of an organic solvent and water, the surfaces of particles of a core substance are wetted with the resulting solution at temperatures of 45 deg.C or below to selectively deposit the wax or the mixture of wax and protein on the particle surfaces and allow them to coat the particle surfaces. And then a slurry containing the particles is subjected to a solvent removal treatment.

Abstract: The spray drying process and the apparatus therefor, of the present invention use a spray drying chamber formed by a heat-resistant porous membrane. Said porous membrane enables rapid separation of a discharge gas and a produced powder and accordingly total recovery of the produced powder from the spray drying chamber. Therefore, there occurs no nonuniformity in product composition; cleaning and blowing-off of adhered fine powder can be conducted rapidly and easily even in frequent product changes inevitable with a less grade larger quantity production system; as a result, a fine powder of higher quality and higher purity can be produced.
