High-Temperature Pyrolysis of Liquified Petroleum Gases in the Fast-Mixing Reactor

Experimental study and computational analysis of a pyrolysis of liquefied petroleum gases (LPG) in a high-enthalpy heat carrier flow are presented. The experiments on a small-scale device were carried out within the temperature range at the reactor inlet of 1,350-1,500 K, which is essentially higher than the typical values in the conventional method of steam cracking. Increased initial temperatures required to realize in the experiments the ultra-fast mixing of the feedstock with heat carrier (~0.05 ms). The rate of feedstock temperature growth in the mixer was about 107 K/s. The ethylene mass fraction in pyrolysis products in our experiments reached 47%.

Keywords: LPG; pyrolysis; olefins; fast-mixing reactor
