Abstract
A hydrotreating apparatus comprising (a') a fixed-bed reactor packed with a hydrotreating catalyst for hydrotreating a heavy oil and (b') a suspended-bed reactor packed with a hydrotreating catalyst for further hydrotreating the heavy oil hydrotreated in the fixed-bed reactor. According to the apparatus of the present invention, (a) feeding of a heavy oil to a fixed-bed reactor is disclosed packed with a hydrotreating catalyst to thereby effect hydrotreating of the heavy oil and (b) feeding of the heavy oil hydrotreated in the fixed-bed reactor to a suspended-bed reactor packed with a hydrotreating catalyst to thereby effect further hydrotreating of the heavy oil can be conducted, and therefore the period of hydrotreating of the heavy oil can be prolonged.
