ABSTRACT
Texaco Research and Development at Port Arthur, Texas recently completed a very successful H-Oil® pilot plant program demonstrating the use of a Texaco/American Cyanamid newly developed catalyst for hydrocracking residual feedstocks at high conversion and still produced stable fuel oils. The operation was carried out in a Process Development Unit wherein catalyst was added and withdrawn daily. Stable fuel oil was produced at 538° C+ (1000° F+) conversion in excess of 80 volume percent. The gas oil and overhead products were treated in an in-line ebullated bed unit (T-STARSM) which produced very clean distillate products (diesel <0.03 wt% sulfur and heavy gas oil<0.15 wt% sulfur).
