What do DCC and FCC mean? What’s the difference?

DCC: Deep Catalytic Cracking process; FCC: Fluidized Catalytic Cracking. That’s what it seems to be.
What are the main differences between the two in terms of manufacturing processes and product specifications?
FCC is primarily used for the production of liquid hydrocarbons, namely gasoline and diesel components; its feedstocks can include atmospheric residue and heavy diesel, among others. DCC is primarily focused on the production of small-molecule gaseous hydrocarbons, namely small-molecule olefins (propylene); it can use conventional catalytic cracking feedstocks, but more often relies on heavy feedstocks. The catalysts and processing conditions vary, but the same equipment can be used. DCC is divided into DCC-I and DCC-II; the former mainly produces small-molecule olefins and certain hydrocarbon and aromatic raw materials, while the latter, in addition to producing small-molecule olefins, can also produce light fuel oils.
What are the differences between the catalytic gasoline and catalytic diesel produced by the two?
