The literature shows that different possible criteria are used for defining biomass fast pyrolysis. On the basis of a simplified modeling of a cellulose (biomass model compound) particle pyrolysis, the present paper points out that the most often considered parameters (i.e., temperature and heating rate) are inappropriate. They are very difficult to define and measure, and according to their ...

An overview of fast pyrolysis of biomass - MAFIADOC.COM
Pyrolysis can be implemented in a reactor or incinerator. In a fluidised bed reactor, for example, waste flows are separated in 2 steps because of different oxygen concentrations in the 2 zones within the reactor. The 'bed section’ consists of a sand mass where drying, pyrolysis and gasification take place. driven and therefore more complex than other types of reactors. In addition, ablative pyrolysis is surface area controlled, so scaling up is difficult. However, for using an ablative pyrolysis reactor as a mobile unit, the scale-up issue is less of a concern. To date, only a few ablative pyrolysis reactors have been devel-oped.

Methods for Producing Biochar and Advanced Biofuels in ...
This paper provides a review of pyrolysis technologies, focusing on reactor designs and companies commercializing these technologies. The renewed interest in pyrolysis is driven by the potential to convert lignocellulosic materials into bio-oil and biochar and the use of these intermediates for the production of biofuels, biochemicals, and engineered biochars for environmental services. Ablative pyrolysis reactors are being researched since 1980s; however, ablative pyrolysis is still under pilot scale studies due to its operational and scale up complexities [85, 92–96]. The ablative pyrolyzer requires simultaneous heating and surface renewal of the biomass feedstock via mechanical (rotating hot disc) or fluid dynamics (inert gas flow in wire mesh) (Figure 6 ).

Abstract. This study deals with a detailed numerical investigation of the microwave heating process in plastic pyrolysis. The pyrolysis of high-density polyethylene (HDPE) was studied using a single-mode microwave cavity, TE10 mode, at 2.45 GHz with two different absorbents, as carbon and silicon carbide, and the results were compared. iv) The operating pressure within the reactor and any pressure drop associated with the flow of the reaction mixture. Reactors used for biomass pyrolysis is most commonly classified depending on the way the solids move through the reactor. 5.2 Types of Pyrolysis Reactor Type A: No solid movement through the reactor during pyrolysis (batch reactors)

Ablative plate pyrolysis reactor Reactors – Summary and status. A summary of some key features of fast pyrolysis reactor systems is shown in the table below, which identifies the more favourable and less favourable features of each type of reactor. Overview of fast pyrolysis reactor … A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
