Abstract�� The influences of pressure on the surface coke deposition of RP-3 were studied by experiments. The flowing RP-3 is heated up to supercritical state in a 2��m long single-pass stainless steel tube��( �� 2.2×0.2, 1Cr18Ni9Ti)�� with constant heat flux. The mass flow is 4��g/s. The mount of surface coke deposition was obtained by weighting method. The influences of pressure on RP-3 surface coke deposition rate were investigated by changing the pressure. The result shows that the greater pressure can suppress coke deposition to a certain extent; the location of coking peak value tends to move backwards along the experimental segment; the shapes of surface coke deposition distribution curve under different pressure are the same.
