| titleOfInvention | Method for preparing purified petroleum benzine and concentrating thiofuran by cruden benzol |
| abstract | The present invention relates to a method for the preparation of pure benzene and the concentration of thiophene from crude benzene. The the prior art which adopts a traditional pickling method and a catalytic hydrofinishing method has the disadvantages of high production cost, complicated technological process, serious equipment corrosion and serious environment pollution, and the thiophene can not be recovered; the present invention which adopts a method of extractive distillation in two stages has the advantages of simple technological process, little equipment corrosion, low cost and high yield, and the resource of the expensive thiophene can be obtained simultaneously. The present invention is a good method for the deep-processing and the utilization of the byproducts of iron and steel enterprises and coking enterprises. |
