Manufacturing method of purified naphthalene |
| abstract |
(57) [Summary] [Purpose] Purified naphthalene is efficiently produced from crude naphthalene by hydrogenation and dehydrogenation. [Structure] The hydrogenation step is divided into a first hydrogenation step for desulfurization and a second hydrogenation step for denitrification. By carrying out dehydrogenation treatment of hydrogenated naphthalene after performing it in stages, and further distilling, subsequent pressing and clay treatment steps can be omitted, and the yield of purified naphthalene can be increased. |
