Biomass pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide.  · Co-pyrolysis of biomass mixture was carried out in a batch pressure reactor (Series 4580 HP/HT, Parr Instrument Company, Moline, IL). Diagram of this set-up is already reported elsewhere . Experiments were carried out at different temperatures: 400, 450, 500, 550, and 600°C.

Request PDF | Production of Biofuels from Algal Biomass by Fast Pyrolysis | Biofuel production from microalgae has been gaining importance in recent years as an alternative (nonpolluting) fuel ... Biomass pyrolysis occurs at a temperature of ∼500°C, forming vapours that exit the reactor and are passed through a cyclone to separate solids, such as char and ash. The energy in the bio-oil vapours is used to heat the recycle gas, leading to the vapours being cooled down to ∼300°C before entering a quench vessel where they are cooled quickly down to ∼20°C by recycling of cold ...

The pyrolysis retort was designed to process biomass with a moisture content up to 30% at temperatures ranging from 450°C up to 600°C (with operation at the higher temperature limited to a maximum of 1 h). The reactor comprises three main sections for: (i) drying, (ii) torrefaction and pyrolysis, and (iii) combustion of the PGVs. Biomass pyrolysis in an entrained flow reactor has been studied by Gorton et al (1990) at the Georgia Institute of Technology, Atlanta, GA, U.S.A. A flow sheet of their process is given in Fig.7.1a. The vertical reactor tube has a length of 6.4m and an internal diameter of 0.15m.

Fast pyrolysis is a high-temperature process in which biomass is rapidly heated to around 500 °C in the absence of oxygen. Biomass decomposes to generate vapors, aerosols, and some charcoal-like char. Fast pyrolysis heating rate is around 100 °C/s, or even 10,000 °C/s and the vapor residence time is normally less than 2 s [].At higher fast pyrolysis temperatures, the major product is gas. fp7,cascatbel,nmp.2013.1.1-1,ence investigacion y desarrollo sau(es),ethniko kentro erevnas kai technologikis anaptyxis(el),outotec (de),abengoa research sl(es),silkem proizvodnja zeolitov doo(si),technische universitat hamburg(de),eni spa(it),nanologica ab(se),fundacion imdea energia(es),eidgenoessische technische hochschule zuerich(ch),mast carbon international ltd(uk),the …

Despite decades of study, the fundamental science of biomass pyrolysis is still lacking and detailed models capable of describing the chemistry and transport in real-world reactors is unavailable. Developing these descriptions is a challenge because of the complexity of feedstocks and the multiphase nature of the conversion process. Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition.The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".. Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood.

Fast pyrolysis and related catalytic pyrolysis are of increasing interest as pathways to advanced biofuels that closely mimic traditional petroleum products. Research has moved from empirical investigations to more fundamental studies of pyrolysis mechanisms. Theories on the chemical and physical pathways from plant polymers to pyrolysis products have proliferated as a • In this process a small amount of air or oxygen is supplied to the wood/biomass & combustion is initiated with sole objective of causing pyrolysis. • If combustion is excessive , fuel energy instead of going into the production of secondary fuel is escaped as sensible heat of the fuel gas.
