  • Patent number: 11713758
    Abstract: A cam ring is capable of moving while rolling on a cam support surface. The cam ring is provided such that within a range in which the cam ring can move on the cam support surface, an eccentricity amount increasing-side angle is always greater than an eccentricity amount decreasing-side angle. On a plane perpendicular to the rotation axis of a driving shaft, the eccentricity amount increasing-side angle is an angle, in a direction opposite to a rotation direction of the driving shaft, from a first reference line, which connects a tangent point between the cam ring and the cam support surface to a rolling center of the cam ring, to a starting end of a first discharge port. The eccentricity amount decreasing-side angle is an angle, in the rotation direction of the drive shaft, from the first reference line to a terminal end of the first discharge port.

    Abstract: It is an object of the present invention to downsize facilities for removing hydrogen sulfide and oxygen in gas and reduce facility cost. Syngas g containing hydrogen sulfide and oxygen as target components for removal or reduction in concentration is contacted with a first material containing transition metal 41 and subsequently with a second material containing transition metal 42 in a first mode. The syngas g is contacted with the second material containing transition metal 42 and subsequently with the first material containing transition metal 41 in a second mode. The first mode and the second mode are alternately executed. In the first mode, iron oxide of the first material containing transition metal 41 reacts with the hydrogen sulfide to become iron sulfide that is reactable with the oxygen and iron sulfide of the second material containing transition metal 42 reacts with the oxygen to become iron oxide that is reactable with the hydrogen sulfide.
