hie im new here and i have 2 questions
im aware that alkylation is a process tat transfers alkyl group fr 1 molecule to another. this is to form more branched chain thus higher octane number of gasoline. my question is when is alkylation process suppose to be performed

my second question is wat is the differences between catalytic cracking and catalytic reforming?

[Sam (NG)]

Alkylation is a general term to describe the transfer of an alkyl group from one molecule to another. It sounds to me as though you are talking specifically about alkylation in reference to petroleum products and production of branched hydrocarbons for high octane fuel products.

I can't claim to be an expert on the oil industry, so I will not just regurgitate wikipedia to you for the answer to your question about the timing of the alkylation process.

...and in fact, I see that the answer to your second question can be found on wiki too: Cracking and Catalytic Reforming (which isn't to be confused with Steam reforming, the main production method of syngas (and hydrogen)).
