| titleOfInvention | Full hydrogenation method for unsaturated hydrocarbon in four-carbon fraction |
| abstract | The invention discloses a full hydrogenation method of unsaturated hydrocarbon in four carbon fractions, which is carried out in a reaction device comprising a first-stage hydrogenation reactor (I), a second-stage hydrogenation reactor (II) and a vapor-liquid separation tank (III), and the method comprises the following steps: and (2) enabling a first carbon four-fraction raw material flow and part of liquid phase materials from the vapor-liquid separation tank (III) to enter the first-stage hydrogenation reactor (I) to perform a first full hydrogenation reaction to obtain a first hydrogenated carbon four-fraction, enabling a second carbon four-fraction raw material flow and the first hydrogenated carbon four-fraction to enter the second-stage hydrogenation reactor (II) to perform a second full hydrogenation reaction to obtain a second hydrogenated carbon four-fraction, enabling the second hydrogenated carbon four-fraction to enter the vapor-liquid separation tank (III) to perform vapor-liquid separation, returning one part of the separated liquid phase materials to the first-stage hydrogenation reactor (I), and enabling the other part of the separated liquid phase materials to be target carbon four-fraction products. The method of the invention effectively saves the materials and energy consumption required by diluting the raw materials and has good economical efficiency. |
