<P>PROBLEM TO BE SOLVED: To solve the problem that there exists the possibility of generating clogging at a part communicating a desulfurization layer before making a turn with a desulfurization layer after making a turn in a hydrogenation desulfurizer as a powdered hydrogenation desulfurizing agent is accumulated on a bottom of the hydrogenation desulfurizer. <P>SOLUTION: The hydrogenation desulfurizer 101 includes: a first desulfurization layer 2 containing the hydrogenation desulfurizing agent; a first support 3 for supporting the first desulfurization layer 2; a second desulfurization layer 6 arranged in the downstream of the first desulfurization layer 2, which contains the hydrogenation desulfurizing agent; a second support 7 for supporting the second desulfurization layer 6; and a communication passage 4 for communicating the first desulfurization layer 2 with the second desulfurization layer 6 at a lower part than the first support 3 and the second support 7 in which the hydrogenation desulfurizing agent is not filled. <P>COPYRIGHT: (C)2013,JPO&INPIT |
