For GTL products, Shell has developed specialized classification methods that assign product yields to hydrocarbon families based on carbon number and degree of branching. At higher carbon numbers, however, molecules with different branching patterns increasingly overlap and can no longer be distinguished reliably. Furthermore, the current classification provides little information on branch location. Such structural information is important for predicting product roperties such as cloud point, pour point, and viscosity, and may provide valuable insights for catalyst development. This project will investigate whether Density Functional Theory (DFT) calculations can support the interpretation of GC×GC data and improve hydrocarbon classification. Specific objectives are: Refine the current classification methodology by distinguishing molecular classes that currently overlap, such as tetra- and penta-branched paraffins or ethyl-methyl substituted paraffins. Assess whether highly branched species (e.g., penta-, hexa-, and hepta-branched paraffins) can be identified more reliably, particularly in highly dewaxed products. Explore whether branch-position distributions can be inferred for lower carbon numbers and whether suitable descriptors can be developed to differentiate catalyst performance and selectivity. - DISCLAIMER: Please note: We occasionally amend or withdraw Shell jobs and reserve the right to do so at any time, including prior to the advertised closing date.
