Title: Isomerization
Inventor: DEBITSUDO HARORUDO ORUSON
IPC: B01J29/40
Filed: 1990-01-10
Abstract: PURPOSE: To obtain an enhanced content of p-xylene by contacting a mixture of ethylbenzene and xylene with a catalyst containing a crystalline aluminosilicate zeolite of a specific average crystal size, a silica/alumina ratio and a constraint index.  
     CONSTITUTION: A mixture of ethylbenzene and xylene in which the p-xylene content is lower than the equilibrium concentration is contacted with a catalyst containing a crystalline aluminosilicate zeolite (e.g.; ZSM-5) of an average crystal size of 1-6 μ, a silica/alumina ratio of larger than 12 and a constraint index of 1-12 to enhance the p-xylene content. Conversion conditions are pref. at a temperature of 260-510°C, at a pressure of 1.7-70 kg/cm 2 G and a weight-time space rate of 1-50. The capacity of adsorption of xylene by zeolite is required to be larger than 1 g per 100 g of zeolite and the time for absorbing o-body up to 30% of the absorption capacity is longer than 10 min. These properties are controlled by a combination with a reduction resistant oxide such as Mg.

Title: Pipe jacking method
Inventor: KOGA KENZO
IPC: E21D9/06
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the execution of works by inserting a curved propulsive body into a linear hole drilled by a rectilinear propulsive body, in which a maximum diameter is specified, and drilling a curved hole after the linear hole. SOLUTION: A front end is formed in a tapered shape in the rectilinear propulsive head 24A of a rectilinear propulsive body 3A while a maximum diameter is set in 1.3 times or more as large as the diameter of a rectilinear propulsive pipe 25A, and an inclined turning pressure-receiving surface 24a is formed at a front end in the curved propulsive head 24B of a curved propulsive body 3B, and the pipe 25A and a curved propulsive pipe 25B are extended in a concentric series shape at the time of soil propulsion. A linear hole in required length is bored by the propulsive body 3A at the time of the execution of works, the pipe 25A and the propulsive body 3A are extracted and the propulsive body 3B is inserted up to the front end of the linear hole. Since the diameter of the head 24B is made smaller than the head 24A at that time, resistance at the time of insertion is lowered.  Upward earth pressure is applied to the pressure-receiving surface 24a by the front end of the linear hole, and the propulsive body 3B is propelled upwards and made to reach an aimed ground-surface place. Accordingly, the linear hole can be drilled easily with high accuracy, and can be made to reach the arrival place of a ground surface accurately.

Title: Arsenic fixation agent and treatment of arsenic-containing wastewater
Inventor: MUKAI KATSUYUKI
IPC: C02F1/62
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To provide excellent arsenic fixation performance even in the condition of higher pH than that for a conventional arsenic fixation agent and at the same time easily precipitate and remove trivalent arsenic from wastewater by adding dithiocarbamic acid derivatives of polyamines or their salts to an arsenic fixation agent. SOLUTION: An arsenic fixation agent to fix and remove trivalent arsenic from wastewater is produced by adding dithiocarbamic acid derivatives of polyamines or their salts and arsenic is removed from wastewater by brining arsenic-containing wastewater into contact with the arsenic fixation agent in pH8 or lower condition and carrying out solid-liquid separation. In this case, the dithiocarbamic acid derivatives of polyamines are compounds having dithiocarboxyl group bonded to at least one nitrogen atom of polyamines containing primary amino group and/or secondary amino group and ethylenediamine is an example of the polyamines. Moreover, it is preferable that the arsenic fixation agent is added in 0.1-10 equivalent to trivalent arsenic.

IPC: C22F1/04
Filed: 1989-01-09
Abstract: PURPOSE:To efficiently heat an ingot without causing dew condensation by specifying a gas flow direction in a direct heating furnace to lower the dew point in an initially charged zone and indirectly heating the zone. CONSTITUTION:An ingot S is charged into the heating furnace 1 from its inlet 5, moved successively through the partitioned a zones 15, heated by a direct-fired burner 23 in each zone, and then extracted from an outlet 8. At this time, a valve 31 in an exhaust pipe 28 is opened to exhaust the combustion gas. When the last ingot S moves into the zone 15B a specified time later and the zone 15A is emptied, the burner 23 there is extinguished, only the valve 31 of the exhaust pipe 28B is closed, and the combustion gas in the zones 15A and 15B flows toward the zone 15D. The external air having a low dew point flows into the depressurized zone 15A from the inlet 5, and the dew point of air in the zone 15A is lowered. In addition, heating of the zone 15A by an indirect burner 27 is started, and the dew point of the air in the zone 15 is made higher than that of the combustion gas without increasing the humidity. By this method, the ingot can be heated without dew being condensed thereon.

Title: Method of improving dehydrating property of organic sludge
Inventor: KASAI TATSUYUKI
IPC: C02F11/14
Filed: 1979-01-12
Abstract: PURPOSE: To very easily raise the velocity of filtration and the percentage of dehydration, by adding hydrogen peroxide to organic sludge in the presence of iron ions and then heating the sludge at 60W100°C for 10W60 minutes.  
     CONSTITUTION: An iron salt such as ferrous sulfate or ferric chloride is added at the rate of 5000W15000ppm to waste water which contains organic sludge. Hydrogen peroxide is then added at the rate of 1000W3000ppm to the waste water in the presence of iron ions from the iron salt. The waste water is heated at 60W 100°C for 10W60 minutes. The pH level of the waste water is thereafter adjusted if necessary. If the molar ratio of FeSO 4 WH 2 O 2  is about 0.8W1.2, the H 2 O 2  reacts well with the iron ions to serve as a strong oxidizer. The velocity of the reaction is raised by the heating. As a result, protein is solidified, the filtering property is improved and the water content of dehydrated cakes is greatly reduced.
