| titleOfInvention | Method for conversion of low-hydrogen heavy oil to light fractions by hydrogenation with hydrogen-supplying hydrocarbons |
| abstract | The invention relates to a method for conversion of low-hydrogen heavy oil to light fractions by hydrogenation with hydrogen-supplying hydrocarbons, which is a process for conversion of heavy oil such as coal pitch by hydrogenation with hydrogen-supplying hydrocarbon stream enriched in hydrogen-supplying hydrocarbons. The method has the effects of inhibiting condensation coking speed, increasing liquid product yield in the process of conversion of coal tar heavy oil to light fractions, improving product quality, reducing reaction temperature increase and enhancing stability and safety of device operation. The hydrogen-supplying hydrocarbon stream can be hydrogenation reaction effluents in partial hydrogenation saturation process of bicyclic aromatic hydrocarbons or polycyclic aromatic hydrocarbons or oil products enriched in partial saturated aromatic hydrocarbons obtained in the separation process of bicyclic aromatic hydrocarbons or polycyclic aromatic hydrocarbons. The precursor substance of hydrogen-supplying solvent oil is coal tar fractions with boiling points of 350-450 DEG C, and the hydrogen-supplying solvent oil mainly comprises hydrocarbon components with ordinary boiling points of 350-450 DEG C. The combination of the method for conversion of coal tar heavy oil to light fractions by hydrogenation and method for conversion of coal tar light fractions by hydrogenation constitutes a novel combined process for conversion of full-range fractions of coal tar by hydrogenation. |
