RESEARCH ON THE MECHANISM OF THERMAL DECOMPOSITION OF HYDROCARBON FUELS

Abstract

The decomposition and particle formation of 28 naphthenic and 8 paraffinic hydrocarbons were studied. The decomposition was approximately a first-order kinetic process, although self-acceleration was observed with most monocyclic hydrocarbons and self-inhibition was observed for polycyclic hydrocarbons. Pressure increased the decomposition rate. A detailed study of the effects of organosulfur contaminants was made. These contaminants inhibited the cracking of naphthenes and straight-chain paraffins and accelerated the cracking of branched paraffins. An increase in contaminant concentration and an increase in the number of methyl substituent groups on a hydrocarbon increased this effect. Several binary hydrocarbon mixtures were cracked. The component hydrocarbons did not crack independently. Nevertheless, the decomposition rate of the mixture could be predicted assuming no mutual interference in decomposition. The micro-coker, a new small-scale device for studying decomposition and deposit formation in a flow system, was developed.
