Vegetable oils (VO) can provide sustainable feedstock to substitute chemicals currently obtained from petrol. VO are majorly composed of saturated or unsaturated fatty acids with 18 carbon atoms (C18), free esterifying glycerol. The monounsaturated C18 acid (C18:1, oleic acid) is industrial interest. Heterogeneous catalytic selective hydrogenation studied maximize the fraction C18:1 in VO. current work investigates modelling point view, examining relation between deterministic models (based on classical ordinary differential equations) and stochastic (implemented by dedicated algorithms). investigation starts experimental data canola oil treated H2 presence commercial Lindlar catalyst. Two reaction schemes were considered develop models. algorithms (Gillespie's simulation algorithm tau-leaping) implemented for simulations. whole simulative was carried out MATLAB® 2023b. model shows that consecutive hydrogenations one double bond per step pseudo-first order rate laws – most straightforward scheme this interpret well, provided variable selectivity values introduced. simulations at different numbers initial molecules allow a multiscale analysis system, confirming reliability chosen suggesting system its thermodynamic limit, sense statistical–mechanics, all investigated conditions.

Fuels should behave appropriately in all sections of the engine system: engine, fuel delivery system, and tank. Fuel quality can be linked to following three crucial areas: performance, fitness for current use, stability. Classical methods diesel examination mostly rely on absolute value measurement one specific parameter while stabilizing outside conditions. In contrast, multiparametric depend simultaneously measuring a set parameters. Therefore, open possibility intriguing new examinations classifications raising issues relating instrumentation construction sensing devices. This paper presents review, based published literature authors’ research, state-of-the-art rapid classification related instrumentation, systematizing various types from point view principles their operation. The main conclusion is that different procedures use similar data processing. Moreover, heavy, costly, complex devices enable standard converted simpler future, whose cost significantly lower. However, achieve this, progress electronic required.
