ABSTRACT:

The main results of two projects out of sixteen are given. Steam reforming of aromatic compounds has shown that dealkylation is faster than ring breakdown. Isomerization and polymerization do not occur. The rate of dealkylation and dehydrogenation decreases with increasing temperature and pressure. Reactivity decreases as the number of aromatic rings in the molecule increases. Coal asphaltenes were shown to contain considerable amounts of hydroaromatic structures which can be dehydrogenated. They alsocontain acid-base structures which are dissociated by reaction with HCl. (ERA citation 05:005282)
