To provide a heavy oil reforming device operated under proper reforming conditions to continuously produce reformate with desired quality when the reformate is produced from heavy oils different in composition.
The heavy oil reforming apparatus includes a reforming apparatus 9 bringing fluid mixture, which is prepared by mixing high-temperature high-pressure water 1a with the high-temperature high-pressure heavy oils together, into a reaction under a reaction condition of high temperature and high pressure to produce the reformate 51a, a reformate analyzer 17 measuring absorbance of the reformate produced by the reforming apparatus, a computing apparatus computing asphaltene concentration in the reformate based on the measured absorbance, and a controller 21 having an operation command computing apparatus computing a command signal based on comparison between the asphaltene concentration and a set point defining the range of desired quality. When at least one of a supply amount of the water, heating quantity of the water, a supply amount of the heavy oils, and heating quantity of the heavy oils is controlled based on the command signal from the operation command computing apparatus, properties of the reformate produced by the reforming apparatus is regulated to the range of the desired quality.
