Reactivity of CO_2 during thermal cracking of heavy paraffins under supercritical conditions

摘要

Thermal cracking of n-hexadecane was investigated in a temperature range of 450-600 deg C in the presence of CO_2. Effects of pressure and temperature on product distribution were experimentally determined under both subcritical and supercritical conditions. At 1.2 Mpa and with a CO_2 to n-C_16 mole ration of 25, C-6C_14 olefins, C_10-C_17 paraffins, and C_5-C_10 fatty acids were identified in the liquid product.
