This study presents the results of the use of fractionation preparative liquid chromatography (PLC) on columns of silica (based on the SARA method, traditionally used for oil samples).For characterization of bio-oils obtained by fast pyrolysis of rice husk. The method distributes compounds separating into four fractions, the majority polar compounds (F3 and F4) and hydrocarbons (F1 and F2). The fractions...
Bio-oil is a mixture of nearly 300 types of organic compounds, including phenols. Phenols are produced during oil refinement and are usually used as fuel additives, food antioxidants and in the synthesis of other chemicals. This study is mainly focused on the extraction of phenolic compounds from bio-oil produced during the pyrolysis of agroindustrial wastes. Bio-oil samples were produced by intermediated...
Microwave pyrolysis technology was used to get bio-oil from fir sawdust. Fir sawdust was mixed with microwave absorption medium (glycerol and ionic liquid) in pyrolysis process. The ratio of absorption medium to fir sawdust was investigated, and result shows that the optimal ratio of glycerol to fir sawdust is 3:1, the optimal ratio of ionic liquid to fir sawdust is 2:1. Fourier Transform Infrared...
