1 day ago  The torrefaction of three representative types of biomass—bamboo, and Douglas fir and its bark—was carried out in a cylindrical-shaped packed bed reactor under nitrogen flow at K of the reactor wall temperature. As the thermal energy for the torrefaction was supplied from the top and the side of the bed, the propagation of the temperature profile of the bed is a crucial factor.   Acoustic emission in I poplar wood under compressive loading. Evaluation of solvent recyclability in fast microwave liquefaction with glycol ether of pine wood for preparation of lignocellulosic micro-fines. Brief Original. One-step preparation of bilayered films from kraft lignin and cellulose acetate to mimic tree bark.

Increasing solvent to biomass ratio also decreased the gas yield when liquefying powdered poplar wood in water. However, contrary results were observed in the liquefaction of C. pyrenoidosa in ethanol.

The only difference in these two experiments was the temperature ( vs °C for the present study).Cited by:   Aqueous liquefaction of Cunninghamia lanceolata, Fraxinus mandshurica, Pinus massoniana Lamb.

and Populus tomentosa Carr. was carried out in an autoclave in the reaction temperature range of – K, where both non-catalytic and catalytic liquefaction were performed. The experimental results show that the lignin content has a large effect on the yield of liquefaction Cited by: One-step method was successfully used to prepare activated carbon fibers from liquefaction of poplar wood bark (ACFs-WB).

• The micropores are dominated in the obtained ACFs-WB which show carbon molecular sieve by: The objective of this study was to investigate the direct deoxy-liquefaction of poplar leaves with two kinds of catalysts (T, Z).

The optimum conditions were found to be at a temperature of. Morphology and pore structure of prepared wood bark based-ACFs (ACFs-WB) were investigated.

Materials and methods. Oven-dried poplar (Populus euramevicana cv. ‘I’) bark was ground and screened to size of 60–80 meshes. Bark powder was mixed with phenol containing concentrated sulphuric acid solution (5%) as a reaction by: With respect to the liquefaction of wood and wood wastes and their use as a liquid fuel, Wu et al.

() liquefied poplar leaves, wood and bark at high temperatures and pressures to produce. Some examples of wood biomass that have been studied as HTL feedstocks are Manchurian ash tree, Chinese pine tree [26] or pine wood powder and saw dust[27][28][29], Chinese white poplar[   The objective of this study was to investigate the effects of water tolerant Lewis acids (i.e., In(OTf) 3, Yb(OTf) 3 and InCl 3) on bio-oil and solid residue this purpose, poplar wood was liquefied at °C with a residence time of 10 min without and with water tolerant Lewis acids in various concentrations from to 10 wt% under hydrothermal conditions.

To make clear the alcoholysis mechanisms of poplar components, the effects of both single and lumped components on the liquefaction rates and product distributions have been studied with acidified 1-octanol as a solvent at °C in an airtight stainless-steel autoclave.

The results showed that single lignin was easy to liquefy, and its liquefaction rate reached wt %. Ind. Eng. Chem. Res. All Publications/Website.

OR SEARCH CITATIONS. Due to the abundance of ash in bark and the lower sintering point of bark ash than that of wood ash, the combustion of bark can lead to fouling which would damage the combustors.

Rapid Hydrothermolysis of Poplar Wood: Comparison of Sapwood, Heartwood, Bark, and Isolated Lignin. Journal of Wood Chemistry and Technology7 (3), DOI: / Alcohol (methanol or ethanol) and water showed synergistic effects on biomass direct liquefaction, and the 50 wt % co-solvent of either methanol−water or ethanol−water was found to be the most effective solvent for the liquefaction of eastern white pine sawdust.

The 50 wt % aqueous alcohol at °C for 15 min produced a bio-oil yield at approximately 65 wt % and a biomass conversion of >95%. With respect to the liquefaction of wood and wood wastes and their use as a liquid fuel, Wu et al.

() liquefied poplar leaves, wood and bark at high temperatures and pressures to produce alkanes. In order to obtain the effects of acid catalysts on wood liquefaction in phenol, we investigated the liquefaction of wood powder from Chinese fir (Cunninghamia lanceolata) and poplar (Triploid Populus tomentosa Carr) in the presence of phenol with the following weak inorganic acids as catalysts: phosphoric acid (85%), sulfuric acid (36%), hydrochloric acid (37%) and oxalic acid (%).

Green wood just stinks. Non-catalytic stoves operate at their most efficient and burn the most cleanly at a moderately hot temperature.

This can be an advantage in leaky old farm houses or huge spaces that need a maximum BTU output to maintain a warm environment. Disadvantages of a Non-catalytic Stove. Briefly, the upstream 1/2″ OD stainless steel solvolysis reactor was packed with 1 g of poplar wood (– g,   The objective of this work is to compare two biomass-to-oil processes: fast pyrolysis and direct liquefaction, using the same biomass (beech sawdust).

Fast pyrolysis is conducted in a cyclone reactor (wall temperature between and K) and direct liquefaction in a mL-autoclave reactor (bulk temperature between and K). Three fractions of pyro-oil are obtained from fast. Oak: Known for its long, slow burns, oak is likely the best firewood wood.

Oak is a dense hardwood available throughout most regions of North America. While oak wood can take a little longer to become properly seasoned than other firewoods, the fire from well seasoned oak in your wood.

Low-temperature swelling of cotton linter cellulose and subsequent gelatinization in trifluoroacetic acid (TFA) greatly enhance rates of enzymatic digestion or maleic acid-AlCl 3 catalyzed conversion to hydroxymethylfurfural (HMF) and levulinic acid (LA).

However, lignin inhibits low-temperature swelling of TFA-treated intact wood particles from hybrid poplar (Populus tremula x P.
