Hydro-Carbons

TermDefinition
Hydrocarbons Made by Hydrogen & Carbon Atoms only
Physical Properties: Hydrocarbons Size
Viscosity: Hydrocarbons Increases as Molecular Increases
Boiling Point: Hydrocarbons Turns Gas as Molecular Increases Size
Hydrocarbons, Combustion Releases Energy, useful Fuel
During Combustion C & H in fuels Oxidised
Complete Combustion Hydrocarbon Carbon Dioxide + Water
Hydrocarbons can be broken down To Useful, more In Demand
Cracking (Stage 1) Large Hydrocarbons heated, vaporise it
Cracking (Stage 2) Hydrocarbon vapour passed over Hot Catalyst
Steam Cracking (Stage 1) Large Hydrocarbons Heated, in order to vaporise them
Steam Cracking (Stage 2) Mixed, water vapour, Heated (High temp)
