“…However, the analysis shows that the maximum (50 wt.%) liquid oil is found at an operating temperature of 500 ∘ C for a feed size volume of 0.15 cm 3 (quarter of date seed) at a gas flow rate of 6 liters/min with a running time of 120 minutes. The effect of these factors on yield has been described in the study of Joardder et al [36]. The main objective of this study is to investigate the effect of solar heating on cost and emission not the effect of product yield parameters.…”

“…Therefore, another renewable energy source, such as solar energy inclusion, may reduce the amount of energy that is required in fast pyrolysis system. It has been found that about 6 kg of rice husk is required to decompose the date seed of 0.4 kg in one cycle [36]. The heating value of rice husk varies between 13.16 and 15.22 MJ/kg as shown in Table 3 [42].…”

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.

“…Hydrocarbon compounds contained in biomass could yield heat energy producing fuels (Fardhyanti and Damayanti, 2017; Montevecchi, 2016). Biomass holds promise as a good feedstock for generating liquid fuels in the imminent future (Demiral and Ayan, 2011; Ilknur et al., 2012; Donate, 2014; Joardder et al., 2015). Biomass particles can be converted into solid char, gases, and condensable pyrolytic vapour as advanced merit fuels (Witchakorn, 2015; Rahmat et al., 2015).…”

“…Bio-oil produced by pyrolysis is a dark-brown organic liquid with a burly bitter smell (Faisal et al., 2011; Wenfei et al, 2018) and it typically possesses lower hydrogen and carbon contents and high oxygen content when compared with fossil fuels (Josilaine et al., 2013; Stefanidis et al., 2013; Joardder et al., 2015). It is thermodynamically an unbalanced liquid but wealthy in functional groups (Josilaine et al., 2013).…”

The Swietenia macrophylla wood used for the study was sun dried for about 48 h, pulverized using a hammer mill and then sieved to a particle size of about 425μm using Wiley milling machine. The prepared materials were pyrolyzed in a fixed-bed pyrolysis reactor in the temperature range from 425 to 500 °C. The product yields were collected at an interval of 25 °C. The maximum yield of bio-oil was recorded as 69.5wt.% at the pyrolysis temperature of 450 °C. The physicochemical properties and compositions of the feed materials and produced bio-oil were measured in order to quantify their potential for bio-energy use and industrial applications. The properties specifically measured include density, moisture content, ash content, pH, refractive index, cetane index, elemental composition, viscosity, and heating values. The ultimate analysis of the product showed that the contents of carbon, oxygen, hydrogen, nitrogen, and sulfur were 50.2%, 42.6%, 6.6%, <0.4% and <0.06% respectively. The viscosity, density, pH, moisture content, API gravity, ash content, HHV and LHV of bio-oil produced were found to be 4.6 mm 2 /s, 0.951 g/ml, 5.64, 21.4wt.%, 19.29, 0.15wt%, 29.52 MJ/kg and 28.08 MJ/kg respectively. These values were found to be in the ranges of values reported in the literature for bio-oils produced from biomass. The produced bio-oil had the much needed organic compounds typical of other woody biomass employed in commercial bio-oil manufacture. These compounds were classified into several groups; organic acids, ketones, phenols, alcohols, and aldehydes. The main components identified in the bio-oil are the aromatic and aliphatic compounds as well as carboxyl groups. The GCMS analysis of the product indicated the presence of 24 compounds which are useful as industrial chemicals and flammable gases: they include alkanes, alkenes, phenols, hydrogen, and levoglucosan. This study on bio-oil has demonstrated that mahogany wood is a useful biomass for the much sort potential fossil fuel substitute and finds vast application in the biofuel industry.

“…Based on that, date industries yield a significant amount of unutilized date seeds (pits) from different processing operations (molasses and paste), which can reach up to 8-15% of the total weight in completely ripe date fruit depending on variety and quality grade (Al-Farsi et al 2007). Lately, date pits have been used for animal feeding and for energy recovery as fuel (Joardder et al 2012).…”

The objective of this study was to optimize the extraction conditions of crude fiber, phenolic compounds, flavonoids, and antioxidant activity from date seeds powder, using Response Surface Methodology. A central composite design with four independent variables; concentration of ethanol (X = 25, 50 and 75% v/v), solvent: sample ratio (X = 40:1, 50:1 and 60:1 v/w), temperature (X = 45, 55 and 65 °C), and extraction time (X = 1, 2 and 3 h) and a three level face centered cube design were used. A total of twenty nine experimental runs with five replicates at the central point were used to study the response variables using two extraction cycles. Maximum phenolic compound content (71.6 mg GAE/100 g) was extracted using 50% ethanol solution with 40:1 solvent: sample ratio for 1 h at 55 °C. While the maximum antioxidant activity (55.02 µmol Fe(II)/g) was obtained using similar ethanol concentration and solvent: sample ratio except at lower temperature (45 °C) for 2 h. On other hand, the maximum flavonoids content (455.77 mg CEQ/100 g) was reached by using 50% concentration, 50:1 solvent: sample ratio at 65 °C for 3 h. In contrast, the content of fiber was not affected by the different extraction conditions. Results indicate that using combination of extracted conditions, have a great potential for extracting all depending compounds except crude fiber.
