本研究的目的是探索铷（Rb）和铯（Cs）的碳酸盐溶液（1 M）的木材生物质的加氢液化（280 degreesC为15分钟）产品在存在和不存在（热）的碱通过使用高压釜的效果。从液体和固体部分提取氧化烃并单独分析。采用气相色谱-质谱联用仪（GC-MS）对油品进行分析。木材生物质的催化水热处理（Rb和Cs碳酸盐）产生的主要是酚类化合物和苯酐衍生物。在热条件下，主要化合物为4-甲基苯酚、2-呋喃甲醛和2-甲氧基苯酚。2-呋喃甲醛和4-甲基苯酚在催化运行中没有观察到。碱催化剂的使用阻碍了炭的形成，有利于油产物的形成。通过使用C-NP gram表征烃（醚提取物）的挥发度分布，并且其显示包括热的所有运行的烃的挥发度分布在n-C-6至n-C-17的沸点区域中。(C)2004爱思唯尔有限公司保留所有权利。
The purpose of the present study is to explore the effect of rubidium (Rb) and caesium (Cs) carbonate solutions (1 M) on the hydroliquefaction of wood biomass (280 degreesC for 15 min) products in the presence and absence (thermal) of bases by using an autoclave. Oxygenated hydrocarbons were extracted from liquid and solid portions and analyzed individually. The oil products were analyzed using gas chromatograph with mass selective detector (GC-MS). Catalytic hydrothermal treatment (Rb and Cs carbonates) of wood biomass produced mainly phenolic compounds and benzenediol derivatives. In thermal case 4-methyl-phenol, 2-furan carboxaldehyde and 2-methoxy-phenol were major compounds. 2-Furan carboxaldehyde and 4-methyl-phenol were not observed in catalytic runs. The use of base catalysts hindered the formation of char and favored the formation of oil products. The volatility distribution of hydrocarbons (ether extract) was characterized by using C-NP gram and it showed that of hydrocarbons for all runs including thermal were distributed in the boiling point region of n-C-6 to n-C-17.
