Energy intensity of hydrocarbons in liquid and solid states

Objectives. The increased use of unmanned aerial vehicles necessitates the search for jet fuels based on hydrocarbon materials with high energy intensity and physical density. purpose work was to analyze influence various factors mass hydrocarbons. This analysis is required substantiate algorithm locating energy-intensive CnHm structures. Methods. Combustion calculated using additive procedures. calculations were performed Microsoft Excel. Results. During hydrocarbons, m/n ratio discovered be decisive factor achieving values decreases when moving from alicyclic cyclic this decrease not compensated by production strain energy. An scheme that allows molar volume hydrocarbons predicted sufficient accuracy proposed calculating volumetric enthalpies combustion. Conclusions. According thermodynamic analysis, n-alkanes have highest intensities. technology extracting oil fractions well developed, a in hydrogen content fuel results intensity. It appears improbable intensities seem will reach their maximum simultaneously. Hydrocarbons value, 2, 3, 4, 5, 6-membered rings, phenyl fragments may relatively at same time.
