五、生產(chǎn)方法：1.由煤焦油分離，高溫煤焦油中萘約占8%-12%，將煤焦油蒸餾，切取煤油，經(jīng)脫酚，脫喹啉，蒸餾得成品萘。2.由石油烴制得：催化重質(zhì)重整油，催化裂化輕循環(huán)油，裂解制乙烯的副產(chǎn)焦油等。

5、 Production methods: 1. Separation from coal tar, naphthalene accounts for about 8%-12% of high-temperature coal tar. Distillation of coal tar, cutting kerosene, dephenolization, quinoline removal, distillation to obtain finished naphthalene. 2. Produced from petroleum hydrocarbons: catalytic heavy reforming oil, catalytic cracking light circulating oil, by-product tar of cracking to ethylene, etc.
