“…At increasing temperatures, solid yields remained almost constant, gas yields increased, and liquid yield decreased. The liquid yields obtained in the presented study are slightly lower, and char yields are higher compared to those of previous studies [18]. These variations are mainly due to compositional differences (moisture, volatile, fixed carbon, and ash content) in biomass feeds and quality of pyrolytic product liquids.…”

The renovation of biomass waste in the form of date seed waste into activated carbon and biofuel by fixed bed pyrolysis reactor has been focused in this study to obtain gaseous, liquid, and solid products. The date seed in particle form is pyrolysed in an externally heated fixed bed reactor with nitrogen as the carrier gas. The reactor is heated from 400• C to 600 • C. A maximum liquid yield of 50 wt.% and char of 30 wt.% are obtained at a reactor bed temperature of 500• C with a running time of 120 minutes. The oil is found to possess favorable flash point and reasonable density and viscosity. The higher calorific value is found to be 28.636 MJ/kg which is significantly higher than other biomass derived. Decolonization of 85-97% is recorded for the textile effluent and 75-90% for the tannery effluent, in all cases decreasing with temperature increase. Good adsorption capacity of the prepared activated carbon in case of diluted textile and tannery effluent was found.

“…Pyrolysis oil derived from agricultural wastes of GCV ranging from 15 to 38 MJ/kg has some advantages in transportation, storage, combustion, retrofitting, and flexibility in production and marketing [14]. The liquid product is useful as a fuel in turbine and other heating systems and it can be added to petroleum refinery feedstock or upgraded by catalysts to produce petroleum grade refined fuels [15]. It is worthy to mention that biooil derived from biomass, which is a mixture of about 300 types of major and minor organic compounds (i.e., acids, alcohols, ketones, aldehydes, phenols, ethers, esters, sugars, furans, nitrogen compounds and multifunctional compounds, etc.…”

Biofuel produced by fast pyrolysis from biomass is a promising candidate. The heart of the system is a reactor which is directly or indirectly heated to approximately 500 ∘ C by exhaust gases from a combustor that burns pyrolysis gas and some of the byproduct char. In most of the cases, external biomass heater is used as heating source of the system while internal electrical heating is recently implemented as source of reactor heating. However, this heating system causes biomass or other conventional forms of fuel consumption to produce renewable energy and contributes to environmental pollution. In order to overcome these, the feasibility of incorporating solar energy with fast pyrolysis has been investigated. The main advantages of solar reactor heating include renewable source of energy, comparatively simpler devices, and no environmental pollution. A lab scale pyrolysis setup has been examined along with 1.2 m diameter parabolic reflector concentrator that provides hot exhaust gas up to 162∘ C. The study shows that about 32.4% carbon dioxide (CO 2 ) emissions and almost one-third portion of fuel cost are reduced by incorporating solar heating system. Successful implementation of this proposed solar assisted pyrolysis would open a prospective window of renewable energy.

“…Biomass is also a versa tile energy source, which can be used for power generation [2] and to produce liquid biofuels [3,4], synthesis gas [5], chemicals [6], or charcoal [7,8], via thermochemical processes such as combustion, gasification and liquefaction. Biomass pyrolysis takes place during these thermochemical processes.…”

Abstract:The thermal decomposition of biomass (pine pellets) and sewage sludge was studied using thermogravi metric analysis under an inert atmosphere and the Distributed Activation Energy Model (DAEM) was employed. The activation energy and the frequency factor that characterize the kinetics were determined for both samples. A simplification of the process for prediction of devolatilization curves was proposed, evaluating its validity for both cases. The simplified method was found to combine both simplicity and low deviations with experimental data.
