超臨界水及び水素供与体を用いた炭化水素からの硫黄除去
Document Type and Number:
Japanese Patent JP2013540856
Kind Code:
A
Abstract:
A hydrocarbon feedstock upgrading method is provided. The method includes supplying the hydrocarbon feedstock, water and a pre-heated hydrogen donating composition to a hydrothermal reactor where the mixed stream is maintained at a temperature and pressure greater than the critical temperatures and pressure of water in the absence of catalyst for a residence time sufficient to convert the mixed stream into a modified stream. The hydrogen donating composition is pre-heated and maintained at a temperature of greater than about 50° C. for a period of at least about 10 minutes. The modified stream includes upgraded hydrocarbons relative to the hydrocarbon feedstock. The modified stream is then separated into a gas stream and a liquid stream and the liquid stream is separated into a water stream and an upgraded hydrocarbon product stream.
