Class 208/54 - Second stage is cracking


Subclass of Class 208 - Mineral oils: processes and products
Definition: Processes wherein the coke producing conversion is followed
No. of patents: 16
Last issue date: 07/29/2008


NumberTitleIssue Date
7404889Hydrocarbon thermal cracking using atmospheric distillation
A method for thermally cracking a hydrocarbonaceous feed wherein the feed is first processed in an atmospheric thermal distillation step to form a light gasoline and atmospheric residuum mixture. The light gasoline/residuum combination is gasified at least in part i...
