Fluid film or hydrodynamic or thick film lubrication Operating conditions: Low load Uniform temperature Moderated speed In this type of lubrication, the sliding metals surfaces or rotating metal surfaces are…

The lubricant is a substance which is introduced between two moving or sliding surfaces to improve efficiency, reduce wear and friction between them, dissolve or remove foreign particles and distribute…

Synthetic gasoline can be manufactured by- Direct method (Bergius process) and indirect method (Fischer tropsch process) Bergius process The coal is finely ground and dried in a stream of hot…

Fischer-tropsch process is carried out to prepare gasoline from non-petroleum origin. The arrangement for charring out this process as Water gas and H2 is sent through Fe2O2 tower where H2S…

Hydrocatalytical cracking The process in which higher hydrocarbon (heavy oil) having higher boiling point is converted into lower hydrocarbon (heavy oil ) having higher boiling point is converted into lower…

The differences between fluid bed catalytic cracking fixed bed catalytic cracking are as Fluid bed catalytic cracking Fixed bed catalytic cracking It is comparatively modern technique. It is comparatively an…

The gasoline and diesel can be compared as follows: Properties Gasoline (petrol ) Diesel Knocking characteristics In a petrol engine, the combustion rate of air-petrol mixture initiated by sparking of…

The advantages of catalytic cracking over thermal cracking are as follows Catalytic cracking takes place at lower temperature and pressure (3000C -4000C and 1-5kg/cm2 ) as compared to that of…
