The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.

What is claimed is: 1. A heavy oil treating system comprising: a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction; a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction; supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit; and extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle. 2. A heavy oil treating system comprising: a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction; a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction, a top end of said nozzle being arranged at a position lower than an upper side of said contact-reaction unit; supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit; and extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle. 3. A heavy oil treating system comprising: a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction; a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction; supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit; extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle; a discharging means for discharging heavy oil components containing metals precipitated in a bottom portion of said contact-reaction unit without dissolving in the high temperature and high pressure water; and burning means for burning said heavy oil components discharged from said discharge means.
