    Steam cracker process diagram Gibbs free energy per carbon atom. This shows that at high temperature, hexane can split into ethane and ethylene ("Ethen"), and ethane can split into ethylene and hydrogen. But ethylene can decompose into methane and carbon if given too much time, and all the hydrocarbons can decompose into carbon and hydrogen.

  3. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    Schematic flow diagram of a fluid catalytic cracker. The catalytic cracking process involves the presence of solid acid catalysts, usually silica-alumina and zeolites. The catalysts promote the formation of carbocations, which undergo processes of rearrangement and scission of C-C bonds. Relative to thermal cracking, cat cracking proceeds at ...

    A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.

  5. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

    The process flow diagram below depicts a typical semi-regenerative catalytic reforming unit. Schematic diagram of a typical semi-regenerative catalytic reformer unit in a petroleum refinery. The liquid feed (at the bottom left in the diagram) is pumped up to the reaction pressure (5–45 atm) and is joined by a stream of hydrogen-rich recycle gas.
