We have developed a hydrogenation process of heavy oil through partial oxidation in supercritical water. For the development of the process, partial oxidation of hydrocarbon and water-gas shift (WGS) reaction in supercritical water are key reactions. In this research, we conducted the basic study of these reactions. The results are as follows.1) Study on partial oxidation of hydrocarbon in supercritical waterPartial oxidation of n-hexadecane (n-C_<16>) in supercritical water was conducted using batch reactors at 400ﾟC and the effect of water density on the partial oxidation of n-C16 was investigated, In the result, the selectivity of CO formation increased with increasing water density.Partial oxidation of methanol and methane in supercritical water was also conducted using a flow apparatus at 380ﾟC - 400ﾟC of reaction temperatures and 10 MPa - 25 MPa of reaction pressures. At lower conversion and higher water density, the selectivity of CO formation increased.2) Measurement of reactio … More n rate of water-gas shift (WGS) reaction in supercritical waterThe reaction rate of WGS reaction in supercritical water was measured using a flow apparatus at 380ﾟC - 400ﾟC of reaction temperatures and 10 MPa - 30 MPa of reaction pressures. The rate of WGS reaction was changed specifically at the critical point of water and increased slightly with increasing water density.3) Study on catalytic hydrogenation of hydrocarbons through WGS reaction in supercritical waterCatalytic hydrogenation of hydrocarbons (naphthalene, carbazole, heavy oil, and so on) through WGS reaction in supercritical water was investigated using batch reactors. The rate of catalytic hydrogenation of hydrocarbons under SCW+CO atmosphere was higher than that under SCW+H_2 atmosphere. Furthermore, the rate of catalytic hydrogenation of hydrocarbons under SCW + CO_2 +H_2 atmosphere was higher than that under SCW+h_2 atmosphere. These results suggest that WGS reaction provides an active species for a catalytic hydrogenation of hydrocarbon in supercritical water.The above results indicate that catalytic hydrogenation through partial oxidation and water-gas shift reaction in supercritical water is an effective method for hydrogenation of hydrocarbons.
