In their computational study, including the neat PRF compounds iso-octane and n-heptane
, kinetic and thermophysical effects on ignition delay times over conditions (600-1100 K, 9 and 60 atm) similar to this study were investigated.
The increase in total flux can be attributed to the following reasons: (a) with increasing temperature, the mass transfer coefficients of the thiophene and n-heptane
increase (as shown in Table 2); (b) the polymer segments also become more flexible and larger available free volume or diffusion path emerge in the membrane; (c) the difference in vapor pressure across the membrane is enhanced with increasing temperature, as a result, the transport driving force of the permeating components is also enhanced.
Table 6 and 7 showed the activities of lipase and phospholipase enzymes in different solvents and results indicated that in n-heptane
, both the enzymes showed their maximum activities.

The feed composition, consisting of n-heptane
, steam, and H2, used for the equilibrium predictions are listed in Table 1, and is the same as employed for the base simulation conditions in the kinetic model.
After centrifugation, the n-heptane
phase was separated and transferred into a headspace vial.
At the present, no significant research work has been reported related to isomerization of lighter hydrocarbon (especially n-hexane, n-heptane
, n-octane, light naphtha, etc.
The validation of the model was previously reported for n-heptane
, n-butanol, and methyl-esters  (+Ewergy & Fuels, 2017, Submitted).
Although the contribution of the increased laminar flame speed with a higher n-heptane
mixture ratio was also expected.
