“…It is well known that minerals can have sensible effects on the thermal behaviour of biomass samples. For this reason the thermal behaviour of washed Miscanthus was also studied (Adam et al 2005;Müller-Hagedorn et al 2003). In our case, we found that a simple washing in water at room temperature leads to a sensible decrease of the ash content as observed by TGA/combustion (solid residue after combustion at 900…”

Miscanthus × Giganteus is an excellent candidate for energy cultivation. Here we report, for the first time, the results of the pyrolysis of Miscanthus × Giganteus straw or pellets both in tubular reactor (3-6 g) and in rotary kiln (10-30 g). At 400-600• C the fractions obtained from both reactors are: solid 16-25 (wt.%); liquids 25-40; water 15-20 and gases 15-50. GC-MS analyses of pyrolysis liquids reveal the occurrence of phenolic derivatives and ethanol from lignin, furanic and linear oxygenated compounds from cellulose and hemicellulose. Finally the chars produced by the pyrolysis of M × G pellets in rotary kiln present good calorific values close to 29,000 J/g. Additionally, activated carbons with a BET surface area as high as 800-900 m 2 /g are produced from pellets. These results indicate that chars have a good potential either for energy production, e.g. briquetting, or as adsorbents precursors.

“…Recently, mesoporous catalysts (such as MCM-41, SBA-15, MSU, etc.) have been applied for their potential to upgrade the large molecular oligomers [8][9][10][11][12][13]. However, due to their poor hydrothermal stability and high production cost, these catalysts cannot be utilized industrially at present.…”

Catalytic Upgrading of Biomass Fast Pyrolysis Vapors with Nano Metal Oxides: An Analytical Py-GC/MS Study

Fast pyrolysis of poplar wood followed with catalytic cracking of the pyrolysis vapors was performed using analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The catalysts applied in this study were nano MgO, CaO, TiO 2 , Fe 2 O 3 , NiO and ZnO. These catalysts displayed different catalytic capabilities towards the pyrolytic products. The catalysis by CaO significantly reduced the levels of phenols and anhydrosugars, and eliminated the acids, while it increased the formation of cyclopentanones, hydrocarbons and several light compounds. ZnO was a mild catalyst, as it only slightly altered the pyrolytic products. The other four catalysts all decreased the linear aldehydes dramatically, while the increased the ketones and cyclopentanones. They also reduced the anhydrosugars, except for NiO. Moreover, the catalysis by Fe 2 O 3 resulted in the formation of various hydrocarbons. However, none of these catalysts except CaO were able to greatly reduce the acids.

“…Lin et al (2013) found that the main compounds in the biocrude oils from thorny bamboo were phenols, carboxylic acids, ketones, and a few furans. Biocrude oils from Pinus indicus were mainly comprised of levoglucosan, furfural, phenol, aldehydes, and vanillin (Luo et al 2004), which was similar to the composition of biocrude oil produced from spruce (Adam et al 2005). Also, the major compounds of biocrude oils from rice straw were acetic acids, formic acids, ketones, and aldehydes, and those from most hardwoods were aldehydes, ketones, and esters (Sipilä et al 1998).…”

Global energy sectors are facing the crucial challenge of sustainability and diversification of energy resources. Seeking renewable resources with a sustainable supply is therefore a matter of the utmost concern. In this respect, bamboo, a renewable lignocellulosic material and non-food biomass, has great potential to be utilized to produce energy. Several studies have been conducted on a wide range of bamboo species and the results have shown that bamboo could potentially be used as a suitable fuel because it shares desirable fuel characteristics present in other woody biomass. Bamboo can be used as an energy source by converting it into solid, liquid, and gaseous fuels. However, to utilize bamboo as a high promise energy crop resource for biofuels, a secure and stable supply is required. Therefore, additional information on the availability, cultivation, and harvesting operations of bamboo is vital to ensure the practicability of the idea. The objective of this review is to highlight the potential of bamboo as an alternative source of bioenergy production, particularly in a Malaysian context, with emphasis on the concepts, pretreatment, and conversion technologies.
