The conversion of tar (gross-formula CH_1.47N_0.01S_0.007) at its continuous supply into a
counter flow of supercritical water (SCW) at the gradient temperature variation
along the vertical axis of the tubular reactor (450 °С at the top, 650 °С at the bottom) at
30 MPa is studied. The yields of liquid products (LP) and volatile С₁—С₉ hydrocarbons
are 41.4 and 28.4 %, respectively, relative to the weight of tar supplied into the reactor.
Methane is the major component (40.5% mol.) of the volatile products; in LP oils
are prevailed (74.4% wt.). Deasphaltization and desulfurization of tar conversion
products are observed. The average rate of water decomposition calculated on the
basis of the O-atoms content in conversion products is 0.24 g/min. It is shown that the
combinations of counter flows of reagents with a temperature gradient along the reactor
axis provides with a higher yield of low-boiling products as compared to that obtained
at SCW pumping through the tar layer.
