Catalyst they have a substance which fastens the Motion of the Motion and Low or delete. But do not put any effect on that reaction as Quantity and Weight. Fertilizer (fertilizer) is the following use in the industry.
i). Hydrogenation
The following component of Natural Gas Sulpher is present.
- H2S, Mercapton sufar
- Sulpher, di sulphides
- Cyclic sulphides
Natural Gas and Recycle Hydrogen is sent in hydrogenation on 39 kg / cm2 pressure and 390 ° C temperature. In this repulsive 8.9m3, Molebedanum catalyst are present. In repulsive carbonic sulfur component H2S becomes hydrogenation.
In addition to the hydrigenation of sulfur Catalyst also gets hydrogenation in the orifines of saturated Hydrocarbon.
ii). Sulphur Absorption
Hydrogation Sulpher Gas 39 kg / cm2 pressure and 350 - 390 °C Sulfur on heat, absorption Tower are absorbed. Each action is 13.8 m2 zinc oxide catalyst. Present H2S in Natural Gas Reaction in the following type from Present Zno in Reactor.
ZnO + H2S ⇌H2O + ZnS
ZnO + CaS ⇌ZnS + CaO
As these reactions are reversible the pressure of water and CO2 in ZnO absorbs feed with influence to absorption equation unfavorable.
Thus the hydrogenesis is free from H2S Jalwapar CO and CO2.
iii). Reforming Catalyst
These are two types.
B. Secondary Catalyst
A. Primary Catalyst
Sulfur at Desulfurised Gas 37 KG / CM2 and 390 ° C Mix with Sulfur Hot Steam. In which the ratio of Steam Carbon 3:3:1 can be made again to the Natural Gas and the Mixture of Steam.
Reforer Feed 34 kg / cm2 Pressure and 505 ° C are made in Primary Reformer. This is the reaction reaction in the tubes which remains in the Gas Reformer, which remains Nio Catalyst.
B. Secondary Reforming
The gas received from primary reformer in Secondary Reformer is combustion and reaction in the present of AIR. It is kept Catalyst on the layer of Nio or MG, Al, Lumps as Catalyst. Al Bricks protects Agtator and Direct Flame Impregment in Catalyst.
From Primary Reformer, partially removed Gas send in SECONDRY REFORMER. Hidrogen and other composition gases in the reformer gas burn with oxygen leaving the nitrogen required to make nh3. The amount of air is fixed by the amount of N2 required for NH3 synthesis.
Other Uses
The main use of catalysts in the fertilizer industry is done to make different chemical reactions sharp or slow.
i. Iron (Fe) and Molybdenum (MO) use this catalyst in the harex process of ammonia production. This process is synthesis of ammonia from nitrogen and hydrogen gases, which is the main component of a nitrogen-based fertilizers.
ii. Vanadium Pantodoxide (V2O5) This catalyst is used in the composition of sulfuric acid production. Sulfuric acid is used in the production of phosphate-based fertilizers.
iii. Nickel (NI) Nickel catalyst is used in hydrogen production, which acts as a source of hydrogen gas in the process of ammonia production.
iv. Calcium oxide (CAO) is often used in various other reactions, such as ammonium nitrate production.
