  • Process and apparatus for producing a reformate by introducing isopentane
    Patent number: 8753503
    Abstract: One exemplary embodiment can be a process for producing a reformate by combining a stream having an effective amount of isopentane and a stream having an effective amount of naphtha for reforming. Generally, the naphtha has not less than about 95%, by weight, of one or more compounds having a boiling point of about 38-about 260° C. as determined by ASTM D86-07. The process may include introducing the combined stream to a reforming reaction zone. The combined stream can have an isopentane:naphtha mass ratio of about 0.10:1.00-about 1.00:1.00.
