Based on the first part of this report the molybdenum loadings of the red mud were varied and the activity of the catalytic additives was tested in a batch autoclave with TJP VR. The 30% Molybdenum loading (sample Nr. 6) was found to be optimum. Further testing with two vacuum residues (TJP VR and ARH VR) and sample nr. 6, indicates the influences of the process parameters for hydrogen pressures of 9-15 MPa, temperatures of 440-475 degrees C and residence times of 0-60 min. Obviously 440 degrees C, 12 MPa and a residence time of 30 min are best conditions for hydrocracking of both vacuum residues with sample Nr. 6.
