Fluidized bed pyrolysis reactors are the most documented and commercially available reactor types amongst all pyrolyzers [29, 31, 32, 37, 38, 43, 89, 90]. The possible factors that limit the liquefaction commercialization could be the lower overall yield of oil (between 2055% w/w) compared to contemporary options like pyrolysis (discussed later), inferior oil quality (heavy tar like liquid), stricter operational parameters (higher reaction temperature and pressure), and requirements of catalysts and/or other reactants (CO, propanol, butanol, and glycerine).

Fixed bed reactor concept for biomass pyrolysis. 0000000756 00000 n Thus, the product gains much higher energy density than the raw biomass, which lowers the transportation cost of the carbonized biomass. Fluidized bed reactor concept is well understood; therefore, it was possible to design and develop pyrolyzers at pilot and commercial scale as many crucial heat and mass transfer models during particle fluidization from prior studies were available. H. R. Appell, The production of oil from wood waste, in Fuels from Waste, L. Anderson and D. A. Tilman, Eds., Academic Press, New York, NY, USA, 1977.

Physicochemical composition of product liquid, Energy and Fuels, vol. 406412, 2009. Even without any transformation, simple tillage practice of crop practice is very important to conserve soil physiochemcial and microbial characteristics. Biofuels are derived from biomass; however, the conversion pathways: biological, physical, chemical, or a combination of processes are pivotal to their type and characteristics. The advantage of this technology is the absence of inert/carrier gas, thereby, relatively smaller energy requirement. Ind Biotechnol 10(6):404412. Thus, technically gasification is an excellent method of extracting bioenergy free from N, P, S, Cl and metals contamination from diverse biomass types without further treatment/upgrading. Energy Fuels 9:855865, Delmer DP, Amor Y (1995) Cellulose biosynthesis. However, complete chemical characterization of bio-oils is practically not feasible due to the formation of pyrolytic lignins, which are randomly broken at different lengths of the polymeric chain [17]. The possible reasons for lack of commercial scale fixed bed pyrolysis reactors could be maintenance problems such as clogging of reactor bed with char and tar compounds, and increased resistance for sweeping gas flow, which could be easily resolved in the other reactor types mentioned in the following.

Advantages of thermochemical conversion of biomass over biological/biochemical process. 887907, 2005. The potential applications of biochar include soil enhancer, bulking agent for composting, activated carbon, remediation of water and soil, energy, and carbon sequestration [26, 51, 52, 54].

The bio-oil yield of recirculating bed reactors is also similar to fluidized bed reactors but reheating of sand/carrier particles requires combustion of entrapped char which may lead to ash build up in the circulating bed.

However, the complexity of agricultural biomass and factors (such as moisture, oxygen, sulfur, nitrogen, and metal contents) makes it a challenging task [10, 1317]. In contrast to bubbling fluidized bed reactors, these pyrolyzers have lower heat transfer but better char attrition due to higher gas velocities via recirculation/reflux.

As it was mentioned above, the utilization of biomass as liquid biofuels is a necessary alternative to avoid harmful effects of direct combustion of biomass (as unprocessed/raw solid fuels) which can led to poor air quality, secondary pollution, and undesired health impacts [2]. Biochar is a pyrolysis byproduct along with bio-oil and flue gases. hb```a``$u@( Eng. The energy and exergy efficiency comparisons indicate the advantages of fossil fuel reforming and biomass gasification over other methods.

This paper intends to explore the physical and chemical characteristics of biofuel substitutes of fossil fuels, potential biomass sources, and process parameters for thermochemical conversion. Carbonization is accomplished by complete conversion of biomass into biochar. The fuel characteristics of bio-oils are in principle due to hundreds of organic compounds that belong to sugars, organic acids, alcohols, aldehydes, ketones, phenols, esters, ethers, furans, nitrogen and sulfur compounds, and multifunctional compounds [44]. 99, no. The structural and compositional complexity of lignin could be assessed by its pyrolysis products such as guaiacol from coniferous wood and guaiacol and pyrogallol dimethyl ether from deciduous woods [47]. Therefore, agricultural biomass has a good potential for the sustainable production of biofuels and valuable products via pyrolysis. 14, pp. Physicochemical characteristics of bio-oils obtained by different processes/biomass types. The potential of vacuum pyrolysis for biomass as well as carbonaceous wastes has also shown some fruitful results after the pilot scale experiments [33, 108]. 1-2, pp. 10, pp. In recent times, biochar is less preferred over bio-oil as fuel source due to handling, incompatibility with transportation sector (automobile engines), storage, and secondary pollutants issues (higher ash content) [37 39].

Bio-oils are the most preferred pyrolysis fuel types for transportation and storage purposes for obvious reasons such as compatibility with many existing equipments, pumping, and safety. Agricultural biomass as an energy resource has several environmental and economical advantages and has potential to substantially contribute to present days' fuel demands. Recirculating fluidized bed reactors are also referred as circulating fluidized bed or transport bed reactors which are more complex version of bubbling fluidized bed reactors (Figure 4).
