Provided are fuel components, a method for producing fuel components, use of the fuel components and fuel containing the fuel components based on 5-nonanone.

Systems and methods for the separation of classes of paraffins from a hydrocarbon sample can include a first column comprising a first zeolite adsorbent material for the isolation of one or more n-paraffins from the hydrocarbon sample and generation of a first eluate including one or more iso-paraffins and one or more one-ring or multi-ring naphthenes. The system can further include a second column, coupled to the first column, comprising a second zeolite adsorbent material for the isolation of one or more iso-paraffins or one-ring naphthenes from the first eluate and generation of a second eluate including one or more multi-ring naphthenes.

Uses for a family of new crystalline molecular sieves designated SSZ-91 are disclosed. Molecular sieve SSZ-91 is structurally similar to sieves falling within the ZSM-48 family of molecular sieves, and is characterized as: (1) having a low degree of faulting, (2) a low aspect ratio that inhibits hydrocracking as compared to conventional ZSM-48 materials having an aspect ratio of greater than 8, and (3) is substantially phase pure.

The present disclosure relates to processes for the removal of paraffins. The processes generally include providing a C.sub.4 containing stream including isobutylene, 1-butene, 2-butene, n-butane and isobutane, introducing the C.sub.4 containing stream into a paraffin removal process to form an olefin rich stream, wherein the paraffin removal process is selected from extractive distillation utilizing a solvent including an organonitrile, passing the C.sub.4 containing stream over a semi-permeable membrane and combinations thereof; and recovering the olefin rich stream from the paraffin removal process, wherein the olefin rich stream includes less than 5 wt. % paraffins.
