Use of alumina spent catalyst and RFCC wastes from petroleum refinery to substitute bauxite in the preparation of Portland clinker

The present study aims for characterization and classification of five different spent petroleum refinery catalysts followed by metal recovery via bioleaching. The nomenclature given to the different spent catalyst (SC) is SC1, SC2, SC3, SC4 and SC5 collected from an Indian petroleum refinery. All spent catalysts were crushed and ground prior to their characterization by X-Ray Fluorescence for chemical composition followed by X-Ray Diffraction and Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy for their mineralogy. Further, all five spent catalysts were classified based upon their chemical composition and mineralogy. Metal recovery from the spent catalysts was carried out by bioleaching by a mixed microbial consortium of iron and Sulphur oxidizing microorganisms. Most of the spent catalysts showed very significant metal recovery with respect to Ni, Cu, Cr, Mo, Zn, Sr and Ti. The study provides a possible metal recovery route via bioleaching for further testing and scaling up.

Spent Catalysts

Petroleum refinery uses many catalysts such as hydroprocessing catalyst HPC, fluid catalytic cracking catalyst FCCC, reforming catalyst RC, etc. During the refining processes, the catalysts are deactivated; the spent catalysts are regarded as hazardous toxic materials due to heavy metals, coke, other poisonous compounds, and hydrocarbons. Huge amount of spent catalysts SC is generated which is expected to increase with expansion capacities of available refineries processes. This paper is reviewing the mechanisms of refining catalyst and the deactivation processes and focusing on spent catalysts management. Management of spent catalyst includes four main options; select the catalysts which reduce the generation of SC by switching to more environment friendly, longer lifetime and less toxic catalyst during the refining process; regenerate the SC; and precious metal recovery should be explored and reuse for other applications. The selection can be based on many factors such as safety, environment, mobility, etc.

Abstract USS 5, Type 501, and 5S, Type 502, contain approximately 5% chromium and 0.50% molybdenum. They resist corrosion and oxidation at elevated temperatures and are particularly adaptable to applications in the petroleum refinery industry. Type 502 contains slightly lower carbon and is used for applications where better weldability is required. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-22. Producer or source: United States Steel Corporation.
