“…At pyrolysis temperature of about 500°C, a maximum yield of about 50% liquid and 30% gas is expected. The holding carbonization time is usually calculated based on the reactor height and the gas flow rates but usually made of several seconds [48]. One major problem of this technique is the low heat produced by the entraining gas which usually leads to low liquid yield since biomass requires high heat for a high liquid yield.…”

Lignocellulosic biomass is a potentially more valuable renewable resource that can be utilized effusively as a chief source of heat for cooking and can correspondingly subsidize the production of electricity, heat, biofuels and chemicals including solid fuel like char or carbon. Lignocellulosic residues are mixed and burnt with coal to generate electricity. Presently, crude oil is replaced by bioethanol and biodiesel produced from biomass substrate. Some special class of chemicals can be derived from biomass that can subsequently replace the usage of non-renewable resources of oil and coal. Pyrolysis of woody biomass to obtain pyroliginous acid was started hundreds of years ago, which has versatile applications. The range of products that can be derived from biomass is huge, prompting extent of research using different types of thermal conversion technologies, including pyrolysis, gasification, torrefaction, anaerobic digestion and hydrothermal processing. This chapter provides insights about the stages of reaction during pyrolysis and the outcome of reaction conditions on the products. Technical development and adjustment of process condition can offer a suitable environmentally benign scheme to increase the energy density of the lignocellulosic residues.

Re´sume´-Une bre`ve revue historique de la pyrolyse rapide de la biomasse -Dans cette revue nous nous proposons de dresser un rappel historique des progre`s relatifs aux technologies de lique´faction thermochimiques par pyrolyse rapide, encore appele´e pyrolyse flash, de la biomasse pour produire ce que l'on appelle commune´ment une "bio-huile". Nous insisterons sur ses applications comme combustible liquide pour la production de chaleur et d'e´lectricite´. Nous ferons ressortir quelques proprie´te´s spe´cifiques aux bio-huiles qui peuvent cre´er des difficulte´s d'usage. Nous terminerons par un bref aperc¸u de quelques proce´de´s permettant de valoriser la bio-huile en carburants liquides de plus forte valeur ajoute´e.Abstract -A Short Historical Review of Fast Pyrolysis of Biomass -In this short review, we survey the historical progress of fast pyrolysis technologies for thermochemical liquefaction of biomass to produce so-called "bio-oil". Our focus is on the potential applications of bio-oil as a liquid fuel for heat and power generation. We point out some of the inherent properties of bio-oil that create difficulties standing in the way of these applications. Finally, we take a brief look at some processes that aim to valorize bio-oil by conversion to higher value liquid fuel products.

“…The reactor was a bottom fed with roughly 1.5 ton/day hardwood biomass and achieved bio-oil yields up to 60 wt % on a dry basis. Georgia Tech Research Institute operated the reactor from 1982 until 1989 [51]. Even though entrained flow reactors may be fed from the bottom which requires large amounts of carrier gas to entrain the feedstock, the reactor shares a tubular shape and may be heated in a similar fashion as a free-fall reactor [43].…”
