包裝：50KG/復(fù)合編織袋裝生產(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。

Packaging: 50KG/composite woven bag production method: 1. It is separated from coal tar, and naphthalene in high-temperature coal tar accounts for about 8% - 12%. The coal tar is distilled, cut into kerosene, and the finished naphthalene is obtained through dephenolization, dequinoline and distillation. 2. Produced from petroleum hydrocarbons: catalytic heavy reforming oil, catalytic cracking light circulating oil, tar by-product of cracking to ethylene, etc.
