Construction is achieved whereby durability is maintained while size and weight are reduced. Installation plate sections are provided on the top and bottom end sections of a pair of support columns. Bolts are inserted through through-holes that penetrate through the installation plate sections in the axial direction; the bolts are then screwed into screw holes provided in the axial direction of anchor sections of an actuator body and a connecting plate, and the bolts are further tightened, whereby the support columns are securely joined and fastened to the actuator body and the connecting plate.

Provided is a practical method for dry-separating arsenic compounds from a used NOx removal catalyst contaminated with arsenic. The method for removing arsenic compounds comprises heat-treating a NOx removal catalyst contaminated with arsenic compounds at a predetermined temperature in a reducing atmosphere while exposing the catalyst to hydrocarbon compounds (except CH) or oxygen-containing carbon compound.

A separation and recovery method that enables titanium and tungsten to be separated and recovered from a used DeNOx catalyst in high yield. Specifically, a method of separating and recovering metal elements that includes a first heating step of heating a DeNOx catalyst containing titanium, tungsten, vanadium and iron in a chlorine atmosphere, thereby removing the vanadium and the iron from the DeNOx catalyst, and a second heating step, performed after the first heating step, of heating the DeNOx catalyst in a chlorine atmosphere while the catalyst is exposed to a gas of a hydrocarbon compound (excluding CH) or an oxygen-containing carbon compound, thereby volatilizing the tungsten and the titanium from the DeNOx catalyst, and recovering the tungsten and the titanium from the DeNOx catalyst.

In this toroidal continuously variable transmission unit, a carrierand a discis brought into direct friction contact with each other, and power transmission between the carrierand the discis implemented by friction force. Because of this, the necessity of machining a gear or claw on the disc or carrier, which has conventionally be done, is obviated, whereby a manufacturing process can be shortened and manufacturing costs can largely be reduced.

This invention relates to a technique for removing nitrogen oxides (NO) present in exhaust gases discharged from boilers and the like. When the temperature of the exhaust gas is 100&#xb0; C. or below, a heat-treated active carbon produced by heat-treating a raw active carbon at 600 to 1,200&#xb0; C. in a non-oxidizing atmosphere so as to remove oxygen-containing functional groups present at the surfaces thereof and thereby reduce the atomic surface oxygen/surface carbon ratio to 0.05 or less is preferably used. When the temperature of the exhaust gas exceeds 100&#xb0; C., a heat-treated active carbon produced by heat-treating a raw active carbon at 600 to 1,200&#xb0; C. in a non-oxidizing atmosphere and activating the surfaces thereof with sulfuric acid or nitric acid to impart oxidizing oxygen-containing functional groups thereto is preferably used.

A flue gas desulfurization apparatus includes at least one activated carbon fiber boardprovided in a catalyst unit, the board being formed by alternatingly juxtaposing one or more plate-like activated carbon fiber sheets and one or more corrugated activated carbon fiber sheets so as to provide vertically extending conduits, wherein water for producing sulfuric acid is supplied, through a capillary phenomenon, to the activated carbon fiber boardprovided in the catalyst unit. The flue gas desulfurization apparatus attains removal of sulfur oxides (SO) by adding a minimum required amount of water to the activated carbon fiber boardso as to attain uniform water distribution and can reduce the amount of water required for removing sulfur oxides (SO).

A high temperature denitration catalyst of a gas turbine single plant contains TiO, at least one of WOand MoOand VOof 0.5 wt % or less, preferably 0.2 wt % or less, or none of VO, and is optimized to be used in a temperature range up to a maximum 450 to 600&#xb0; C. The used high temperature denitration catalyst is immersed into a V-containing water solution and dried and/or burned. An intermediate temperature denitration catalyst is produced containing a VOcomponent of 0.5 wt % or more, preferably 1.0 wt % or more, and is optimized for use in a temperature range of 250 to 450&#xb0; C. This intermediate temperature denitration catalyst is re-used in a combined cycle plant after being modified or in other plants.

In the inner and outer surfaces of the retainerthere are formed recessed grooveswhich serve as lubricating oil flow passages for allowing lubricating oil to flow into pockets. Where the axial-direction depth of the recessed grooveis expressed as H and the circumferential-direction width thereof is expressed as 2L, 0.20&#x2266;H/L&#x2266;0.97 can be satisfied. Accordingly, it is possible to provide a toroidal-type continuously variable transmission which can prevent the damage of a retainerincorporated into a thrust rolling bearing for supporting a power roller and also can enhance the lubricating efficiency of the present thrust rolling bearing.
