A selective extraction method for recovery of monofunctional methoxyphenols from biomass pyrolysis liquids

Separation of Biomass Pyrolysis Oil by Supercritical CO2 Extraction

Supercritical CO2 extraction was employed to separate simulated and real bio-oils. Effects of extraction pressure, temperature and adsorbents on distribution coefficient (or enrichment coefficient) of five representative compounds were investigated using a simulated bio-oil, which was composed of acetic acid (AC), propanoic acid (PA), furfural (FR), acetylacetone (AA) and 2-methoxyphenol (MP). ...

Kinetic models for biomass pyrolysis

Biomass is a versatile material. It can be directly combusted to produce heat; however, by first subjecting it to a thermal or biological degradation, it can also be converted to products with a higher heating value or to materials with properties superior to those of the raw material [1]. When heated in the absence of oxygen, biomass decomposes into a range of products; including char (solid),...

Biomass Pyrolysis for Hybrid Biorefineries

Effect of Catalytic Pyrolysis Conditions Using Pulse Current Heating Method on Pyrolysis Products of Wood Biomass

The influence of catalysts on the compositions of char and pyrolysis oil obtained by pyrolysis of wood biomass with pulse current heating was studied. The effects of catalysts on product compositions were analyzed using GC-MS and TEM. The compositions of some aromatic compounds changed noticeably when using a metal oxide species as the catalyst. The coexistence or dissolution of amorphous carbo...

Determination of an Efficient Extraction Method of Xylan From Biomass

Sources •Biofuels are becoming more widespread throughout the United States as more advanced conversion methods become available. The most advanced process at this point is the conversion of biomass into ethanol (5). However, research into biofuels other than ethanol is an important aspect of the DOE’s mission to promote the spread of renewable energies. Before progress can be made in these are...
