Oiland gas in the oil sand will be obtained by carbonization experiment. Gas and liquid product will beby condensation. Comparative analysis will be carried out by cooperating with aluminum retort and industrialanalysis. Heating curve and heating rate of oil sand in oil sand carbonization, the yield of oil sand, distribution andrm of sulfur will be obtained to test the applicability of carbonization process, to provide lab support by perfectand suitable carbonization processing route and all kinds of carbonization parameters and to gain experience anddata for the subsequent industrialized production. The experiment result shows that carbonization is suitable formaking oil by oil sand. Oil solidifying point of oil sand is very low, the calorific value of gas is high and can reachcarbonization terminal at 550C.
