“…The analysis shows that carbon and oxygen were the principal components of the sample (58.07% and 27.24%, respectively). The hydrogen (8.19%) and nitrogen (4.61%) contents of the sample were similar to those previously reported for cherry seed and rapeseed (Duman et al, 2011;Ucar and Ozkan, 2008). The nitrogen is associated with the quantity of proteins present in the mangaba seeds (12.10 ± 0.36%).…”

“…According to the biomass used, a mixture of different compounds will be obtained in the thermochemical conversion process, namely pyrolysis, which is applied to chemical transformation (Ucar and Ozkan, 2008). According to Zilnik and Jazbinnsek (2012), this process occurs in the absence of oxygen and the presence of an inert gas (helium or nitrogen), and it generated gaseous (carbon monoxide, carbon dioxide and light hydrocarbons), solid (biochar) and liquid (bio-oil).…”

The aim of this study was to evaluate the potential of Hancornia speciosa GOMES (mangaba) seeds as a novel matrix for the production of bio-oil. The study was divided into three steps: (i) characterization of the biomass (through elemental analysis (CHN), infrared spectroscopy (FTIR-ATR), thermogravimetry (TG), and determination of biomass composition; (ii) pyrolysis of mangaba seed to obtain the bio-oil; and (iii) characterization of the bio-oil (thermogravimetry and gas chromatography/mass spectrometry-GC/qMS). The TG of the sample showed a mass loss of around 90% in 450°C. In the pyrolysis experiments the variables included temperature (450 and 600°C), sample mass (5 and 11g) and prior heating (with or without), with the best conditions of 600°C, 11g of seeds and prior heating of the furnace. The GC/qMS analysis identified carboxylic acids and hydrocarbons as the major components, besides the presence of other compounds such as furanes, phenols, nitriles, aldehydes, ketones, and amides.

“…Biomass can be converted into fuel products through different thermochemical processes, among which pyrolysis is considered as a prospective and effective technology to produce valuable bio-oils, char and gaseous [7][8][9]. Especially, the bio-oils obtained from pyrolysis processes are attractive and considered to be a very promising biofuel as their high energy density and convenience in usage, storage and transport [10].…”

“…The total production of rapeseed plant all around the world was 46.2 Mt in 2005 (Prakash and Stigler 2012). Taking the 5th place among oilseed crop, the production of rapeseed oil in the world was 17.9 Mt in 2005 (Ucar and Ozkan 2008). Its oil is classified as one of the healthiest vegetable oils because of its fatty acid composition: triglycerides 97-99 wt%, fatty acids 0.5-2 wt%, and minor lipids 0.5-1 wt% (Boutin and Badens 2009).…”

Instant controlled pressure drop process (DIC) was used to texture rapeseeds in order to intensify oil extraction performances of both pressing and solvent extraction processes. Solvent extraction from both DIC-textured and non-treated raw material RM seeds was achieved with n-hexane using separately accelerated solvent extraction (ASE) and dynamic maceration (DM). ASE allowed quantifying the extraction yields while the extraction kinetics issued from DM experimental data was studied through coupled washing/diffusion CWD phenomenological model. ASE oil contents were 622.5 ± 0.5 and 664.4 ± 0.5 g oil/kg dry dry basis ddb for untreated and DIC-textured seeds, respectively. In terms of kinetics, 45-min DM of DIC-treated seeds implied higher yields than 8-h DM of RM (467.8 ± 0.5 against 435.6 ± 0.5 g oil/kg ddb). Moreover, pressing oil yields reached 553.5 ± 0.5 against 490 ± 0.5 g oil/kg ddb for DIC and RM seeds, respectively. Besides, optimized DIC treatment allowed obtaining preservation of lipid fatty acid profiles.
