The calcium ion-exchange moso bamboo was subjected to microwave heating investigate into the influence of ion on its pyrolysis. dependence method pyrolysis behavior also researched. calcium-loaded samples gave very different behaviors from that demineralized sample based results thermogravimetric analysis. found facilitate production solid and gaseous products at expense bio-oil. relative conte...

the purposes of this article are studying the effects of oxygen presence on waste wood pyrolysis process in order to produce bio-char. to reach the goal, cubic samples of size 2.5 cm pyrolized at 300 and 400 °c. the surface and center temperatures of samples were measured and their mass losses were calculated from the ratio of pyrolized mass to initial mass of the sample. increase in temperatur...

Biomass pyrolysis is a promising technology for fuel and chemical production from an abundant renewable source. It takes place usually in two stages; non-catalytic with further catalytic upgrading of the formed oil. The direct biomass reduces temperature, increase yield to target products improves their quality. However, such one-stage process contact between solid catalyst particles poor leadi...

Fast pyrolysis has been a subject of intensive research thanks to its ability produce high yields liquid products, known as oil. This is an important renewable intermediate which could be used for the subsequent production fuels and chemicals. For fossil-based materials, oil can provide circular building blocks. Furthermore, direct use in gas turbines also proven feasible. However, relatively o...

The co-pyrolysis of waste electrical and electronic equipments (WEEEs) and waste biomass to obtain pyrolysis-oil, a liquid fuel or chemical feedstock, was carried out in the present work. The pyrolysis-oil yield of co-pyrolysis reached 62.3% which was significantly higher than those of pyrolysis of WEEEs and biomass alone (i.e., 53.1% for WEEEs and 46.3% for biomass), suggesting that synergisti...

Tar and char can be regarded as unwanted byproducts during the gasification process. In this study, three types of catalyst, i.e., biomass char (bio-char), nickel supported on biomass (Ni+bio-char), and nickel supported on bio-char (bio-char+Ni), were studied to compare the catalytic effects of different preparation methods on tar model compound removal. The structural characteristics of the th...
