Desalting- else accelerate corrosionof metals, deactivate catalysts 1 of 15 How is desalting done? by physical process followed by electrostatic separation 2 of 15 Why do we need to remove sulphur from crude oil? Will creat sulfuric acid when undergone certain processes and poison catalysts 3 of 15 What is S good for? And by what process? making sufuric acid and fertilisers 4 of 15 By what process is sulphur removed and then recovered? hydrodesulphurisation and Clause process respectively 5 of 15 What is wrong with heavy chain alkanes that we need to crack them? not very reactive 6 of 15 What is the common feedstock of cracking? Naphtha fraction (C7-C14) 7 of 15 What are the 3 types of cracking? List in terms of which is lastest fluid catalytic cracking, steam cracking, thermal cracking 8 of 15 List in order products of FCC? carbonium ion, alkane or dihydrogen, carbenium ion, alkene 9 of 15 Why do unbranched alkanes crack faster than branched alkanes? Catalysts reject branched chain due to poor size 10 of 15 What is the catalyst in FCC? Zeolite, containing mineral clays 11 of 15 Which component has 100% octane value and which has 0%? 2,2,4-trimethylpentane and n-heptane 12 of 15 By what process can naphthas be converted into cyclic alkanes? Why do we do this? Catalytic reforming, higher octane value 13 of 15 What are the 3 main petrochemicals? Ethene, propene, benzene 14 of 15 Describe 1 method to obtain sulphur which was previously used? taken from undergound deposits 15 of 15
