Delivery time: 8-12 business days (International)
Oktanovoe chislo yavlyaetsya pokazatelem, kharakterizuyushchim detonatsionnuyu stoykost' topliva dlya dvigateley vnutrennego sgoraniya. Proizvodstvo vysokooktanovykh tovarnykh benzinov osushchestvlyaetsya putem kompaundirovaniya. Zadachi optimal'nogo upravleniya protsessom kompaundirovaniya privodyat k neobkhodimosti razdel'no otsenivat' detonatsionnuyu stoykost' ego razlichnykh fraktsiy. Uglevodorody, kotorye soderzhatsya vo fraktsiyakh, znachitel'no razlichayutsya po detonatsionnoy stoykosti (raznye znacheniya oktanovogo chisla). Otsenka ikh detonatsionnoy stoykosti na osnove rascheta energii dissotsiatsii molekul pozvolyaet nadezhno rasschitat' oktanovoe chislo smesheniya dlya optimizatsii protsessa kompaundirovaniya s tsel'yu polucheniya vysokokachestvennoy produktsii. V dannoy knige opisyvaetsya matematicheskaya model' rascheta oktanovykh chisel tovarnykh benzinov i razrabotka metodiki opredeleniya oktanovykh chisel individual'nykh uglevodorodov na osnove rascheta energiy dissotsiatsii molekul s ispol'zovaniem kvantovokhimicheskikh metodov rascheta. Issledovanie zavisimosti oktanovykh chisel ot energii dissotsiatsii pozvolyaet sozdat' bolee tochnuyu, uchityvayushchuyu yavlenie detonatsii, matematicheskuyu model' rascheta oktanovykh chisel dlya protsessa kompaundirovaniya benzinov.
