Heavy oil is heated in preheated to a temperature of about 425-4500C. the resulting vapours oil is charge is then forced through the catalytic chamber. The catalytic chamber is maintained…

Solid catalyst is very finely powdered (fluidized) so that it behaves almost like a fluid and can be circulated in the gas stream. Vapours of heavy and fluidized catalyst are…

Cracking is defined as a process where hydrocarbons having higher molecular weight and boiling points are converted to hydrocarbons having lower molecular weight and boiling points. The objectives of cracking…

Blending is a process of mixing gasoline or petrol with cracked and reformed gasoline, alcohols, benzene etc to increase its octane number and anti-knocking characterize. Diesel oils are not blended.…

In a diesel engine, if the combustion rate of air diesel mixture initiated due to compression of air becomes very slow then a large amount of fuel collected in the…

Advantages of geothermal energy The cost of the land build a geothermal power plant is usually less expensive. The plant occupies less space. No fuel is used for power, rate…

Knocking tendency of petrol in a petrol engine is expressed by its octane number. The combustion characteristics of iso-octane i.e. 2, 2,4- Timothy pentane (C8H18) is very good. It has…

Knocking tendency of diesel in a diesel engine is expressed by its cetane number. The compression so it produces less knocking. Hence its cetane number is taken as 100. On…

The air-fuel mixture burns moderately and uniforms at a rate in the cylinder of internal combustion (IC) engine. The metallic or rattling sound in the cylinder of internal combustion engine…
