GCMC`s integrated process for recovery of metals from spent catalysts
- Gulf Chemical and Metallurgical Corp., Freeport, TX (United States)
Petroleum refining is one of the largest manufacturing and processing industries in the world. In the US there were 185 refineries in 1992. Some of the refining operations require the use of catalysts that contain mainly nickel, cobalt, and molybdenum on an alumina matrix. Upon deactivation, spent catalysts also contain vanadium, sulfur and minor impurities such as phosphorus and arsenic. Gulf Chemical and Metallurgical Corporation (GCMC) operates an integrated facility for metals recovery from spent hydroprocessing catalysts in Freeport, Texas. The recovered metals are directly reused for the manufacture of catalysts and production of ferroalloys. Fused aluminum oxide is recycled to the ceramic and refractory industries. This paper will discuss GCMC`s contribution to the recovery and reuse of metals contained in spent catalysts over the last fifty years.
