Pyrolysis Of Biomass

Ex-situ catalytic fast pyrolysis (ex-CFP) of biomass applying ZSM-5 catalysts is an effective method for deoxygenating the pyrolysis vapour, thus producing low-oxygen bio-oil in a single step. The catalysts deactivate...

Pyrolysis Of Biomass

Energy can be produced from biomass by biochemical, biological and thermal process. Pyrolysis is a thermal process that operate at temperature between 400-600C in absence of oxygen or with very low amount, to produce a bio-oil, char and gas. The best technology is fast pyrolysis that produce higher amount of liquid bio-oil, particularly 75% of liquid, -at 500oC without oxygen, contact time lesser 2sec a drying of biomass till 10%, with dimension of particles of biomass of 3mm, using mainly bubbling fluid bed, However the bio-oil obtained with fast pyrolysis present a lot drawbacks: it presents a high amount of oxygen, high acidity, high viscosity, high moisture and chemical instability. Fast pyrolysis can be upgraded operating in the presence of a catalyst (in-situ) or with a downstream catalytic reactor to the that one of fast pyrolysis (ex situ). Besides it is possible upgrade the bio-oil transforming it in fuels and chemical products realizing the catalytic pyrolysis in presence of H2 (hydropyrolysis) or realizing hydrodeoxygenation reactions downstream the fast pyrolysis or using as reductants wastes from plastics, from rubber of tires or from organic wastes in order to realize a catalytic co-pyrolysis.

Pyrolysis Of Biomass

The non-oxygenated fraction of bio-oil is precursor of the formation of biofuel because it contains hydrocarbon only. Zeolite catalysts have been proved to improve the yields of non-polar fraction of bio-oil in case of fast co-pyrolysis. In the present work, the catalysts were applied to slow co-pyrolysis to investigate their effect on the yields and compositions of non-oxygenated fractions of bio-oil. The co-pyrolysis was conducted in a stirred tank reactor using non catalyst (thermal co-pyrolysis), natural zeolite and H-beta zeolite catalysts with heating rate of 5°C/minute from ambient temperature to 500°C and PP composition in combined feed varied 0, 50, and 100% weight of PP. As biomass, the present study used corn cobs. The results show that synergistic effect on the yield of non-oxygenated fraction in co-pyrolysis involving natural zeolite was lower than that in thermal co-pyrolysis and co-pyrolysis involving H-beta-zeolite exhibited negative synergistic effect. H-NMR analysis of the fraction from co-pyrolysis involving 50% weight of PP shows that the bio-oil contained approximately methyl H of about 55% by mol, methine H of 20% and methylene H of about 15% irrespective of catalysts used. This composition was closer to that of commercial gasoline rather than commercial diesel compositions.

Pyrolysis Of Biomass

Biomass such as agriculture waste and urban waste are enormous potency as energy resources instead of enviromental problem. organic waste can be converted into energy in the form of liquid fuel, solid, and syngas by using of pyrolysis technique. Pyrolysis process can yield higher liquid form when the process can be drifted into fast and flash response. It can be solved by using microwave heating method. This research is started from developing an experimentation laboratory apparatus of microwave-assisted pyrolysis of biomass energy conversion system, and conducting preliminary experiments for gaining the proof that this method can be established for driving the process properly and safely. Modifying commercial oven into laboratory apparatus has been done, it works safely, and initial experiments have been carried out, process yields bio-oil and charcoal shortly, several parameters are achieved. Some further experiments are still needed for more detail parameters. Theresults may be used to design small-scale continuous model of productionsystem, which then can be developed into large-scale model that applicable for comercial use.
