| titleOfInvention | Treatment method and coating pretreatment liquid for reducing coking of furnace tube of hydrocarbon cracking furnace |
| abstract | The invention relates to a treatment method and a coating pretreatment liquid for reducing coking of a furnace tube of a hydrocarbon cracking furnace. The method comprises steps of vapor deposition and passivation treatment; the solute of the coating pretreatment liquid which is used in vapor deposition is a compound component A containing an element with anticoking performances, or the component A and a compound component B containing a doped element, the element with anticoking performances in the component A is selected from one or more of Si, Al, and Ti, the doped element in the component B is selected from one or more of Cr, rare earth elements, alkali metals, and alkali earth metals, and a weight ratio of the component B to the component A is (0-0.5):1; and the solvent of the coating pretreatment liquid is selected from one or more of water, methanol, ethanol, glycol, benzene, toluene, ethylbenzene, and tetrahydrofuran, and the concentration of the coating pretreatment liquid is 1-15 wt%. The method of the invention which has the advantages of simple technology, convenient implement, and environmental protection and has no adverse influence on downstream systems allows the coking amount in cracking processes to be effectively reduced and the operation period of the cracking furnace to be prolonged. |
