PURPOSE:To provide a compact reactor whose catalyst has excellent vibration- resistance. CONSTITUTION:A case 3 is composed of a lower portion 4 having an inlet 6 for exhaust gas and an upper portion 5 having an outlet 7. Prismatic catalysts 1 in the lower portion, each having a right angle between a running direction of a ship and a longitudinal direction, are superposed in a dislocating manner rightward with a specified measurement in a longitudinal direction, and held by a support reticle 8. The catalysts in the upper portion are superposed in a dislocating manner leftward. Exhaust gas flowed from the inlet does into a space S2 through a space S1 and a lower catalyst. The exhaust gas reaches the outlet through the upper catalyst and a space S3. A transverse measurement of a reactor is indicated by a formula of c+a+b, which is smaller than the conventional transverse measurement indicated by the formula a+2b. The conventional measurement is obtained by the measurements (b) on both ends of the catalysts superposed in the flat manner. The catalysts are horizontally arranged, whose longitudinal direction is perpendicularly arranged to the running direction of the ship for improving vibration-resistance. |
