项目摘要

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.

我们通过在超临界水中的部分氧化开发了重油的氢化过程。为了开发过程，超临界水中烃和水电偏移（WGS）反应的部分氧化是关键反应。在这项研究中，我们对这些反应进行了基本研究。结果如下。1）研究在超临界水氧化中的碳氢化合物（N-C_ <16>）在超临界水中的超临界水生氧化中的一项研究，该研究使用400 c的批处理反应器进行了批处理反应器，并研究了水密度对N-C16的部分氧化作用，并增加了对N-C16的氧化氧化的影响，并增加了甲基化的水，并增加了甲基化的量。还使用反应温度的380°C -400 c -400 c -400 c -400 c -400 mPa -25 mPa的反应压力的流动设备进行超临界水中的甲烷。在较低的转化率和较高的水密度时，CO形成的选择性提高。2）测量反应……在超临界水中，水气转移的速率（WGS）速率更高。使用380 c -400 c -400 c -400 c反应温度和10 mpa -30 mpa -30 mpa的反应温度C -400 c -400 c -400 c -400 c -400 c -400 c -400 c反应在超临界水中的WGS反应速率。 WGS反应的速率在水的临界点上进行了特异性更改，并随水密度的增加而略有增加。3）研究通过WGS的超临界水催化氢化在碳苯甲苯，碳酸盐，碳唑，碳唑，重油等中，通过使用超临界水的反应在超临界水的超临界水催化氢中研究的研究。在SCW+CO大气下，烃的催化氢化速率高于SCW+H_2大气下的催化氢化速率。此外，在SCW +CO_2 +H_2下，烃的催化速率高于SCW +H_2大气下的催化氢化速率。这些结果表明，WGS反应为超临界水中烃的催化氢化提供了一种活性物种。以上结果表明，通过部分氧化和超临界水中的水和加气偏移反应催化氢化是一种有效的碳氢化合物氢化方法。较少的
