Catalysts can be divided into two main types - heterogeneous and homogeneous. Nickel is found in many ores as sulfides, arsenides, antimonides & oxides or silicates; chief sources include chalcopyrite; others are pyrrhotite, pentlandite, garnierite, niccolite, millerite. Nickel prices are the highest of the common non-ferrous metals. Nickel is easier than palladium to remove at the end of the manufacturing process, so it’s also less expensive to purify the finished product. A process for nickel recovery from a spent catalyst of definite composition has been developed using the hydro-metallurgical route. The processing steps includes direct sulphuric acid leaching followed by separation of iron as well as silica and other impurities. The nickel based catalysts are widely used in industry, e.g., in hydration, alkylation, hydroalkylation reactions, cracking proceses. The catalyst provides high activity a low de-activation rate, and resistance to changes in the atmosphere. Raney nickel is a solid catalyst composed of fine grains of a nickel-aluminium alloy, used in many industrial processes. Raney-type catalysts were first introduced in 1924; since then, these catalysts, both in powdered and granular form, have been widely used in many commercial processes, including hydrogenation of unsaturated organic compounds, such as the catalytic hydrogenation of adiponitrile to hexamethylenediamine, and of benzene to cyclohexane; they have also been used in reductive reactions, as in the alkylation of carbonyl compounds with amines; in the hidrogenolysis of esters and ethers; in fuel cell electrodes and in dehalogenation Raney nickel is produced when a block of nickel-aluminium alloy is treated with concentrated sodium hydroxide. Activated Nickel Catalyst has a very wide and growing applications in chemical industry. They are most commonly used in slurry phase hydrogenation in batch processes using stirred autoclave. Spent nickel catalyst is generated by various chemical and industrial processes particularly in hydrogenation of natural oils and fats. The new nickel-tin catalyst is cheap enough to compete in the electricity and fuel markets, provided the sugar water feed stock is available at low cost. The nickel based catalyst are harmful for environment and nickel is a precious element, so the particular attention is paid to the recycling of spent catalysts and to the extraction of nickel and other useful components There are two possible recycling types of processes: pyroprocesses and hydroprocesses . In evaluating the market for catalysts used in refineries to produce fuel, there is a fact that catalysts are sold into two markets - new units being built to meet the additional demand and existing units that continue to reload catalysts.
