The structure and composition of tars from the flash pyrolysis of one brown and two bituminous Australian coals were investigated by 'H n.m.r. spectroscopy. Reaction times in a fluidized bed were about 1 s. For each tar the aromatic hydrogen content increases slightly with pyrolysis temperature up t

Asphaltenes derived from tar from the flash pyrolysis of Millmerran coal have been separated into acid, base, polyfunctional and neutral fractions by ion-exchange chromatography. Each fraction was studied by high-pressure catalytic hydrogenolysis followed by g.c.-m.s. analysis of the volatile produ
Tar free from influences of the original coal or char was cracked in two reaction systems, one using tar vapour in tubular quartz reactors at 9OG1400 K and reactor residence times of = 0.2 and = 1 s, the other using tar aerosol in a shock tube at I1 O&2000 K and residence time = 1 ms. In the latter
The performances of 1 g h-' and 20 kg h-' flash pyrolysers are compared for three Australian coals: Loy Yang brown coal (Victoria), Liddell bituminous coal (New South Wales), and Millmerran subbituminous coal (Queensland). The two reactors gave comparable yields of tar, char and Cl-C3 hydrocarbon ga
