AbstractThe study depicts the production, optimization and characterization of bio-oil from pyrolyzed rice husk using a fabricated fixed bed reactor. The pyrolysis process was conducted with bio-oil response, bio-char response and non-condensable gases response as products. The effect of pyrolysis variables were observed by the production of the bio-oil as the response. Sixty runs of pyrolysis experiments were suggested by Box Benkhen design indicated optimum pyrolysis conditions at particle size of 2.03mm mesh, reaction time of 81.80 mins and temperature of 650oC for rice husk. The maximum bio-oil yield was obtained with 38.39% at optimum condition of the variables. The bio-oil sample obtained had better performance compared with ASTM standard. Such a determination would contribute so immensely to a significant comprehension of the chemical efficiency of the pyrolysis reaction.

The macambira (Bromelia laciniosa) is a plant from the Bromeliaceae Family, Bromeliad genus, found in the Brazilian Northeast, highly resistant to dry climates. It has no commercial value. The aim of this study was to evaluate the potential of the macambira for ethanol production. For this, samples were collected in the rural area of Nova Floresta in the state of Paraíba, where the leaves were cut into small pieces, and then went through a process of drying in circulating air and went through a process of milling. The chemical characterization of the leaves was performed in order to determine the moisture, extracts, cellulose, hemicellulose, lignin and ash content. During the chemical characterization the following values were obtained; 8.14 ± 0.08% moisture, 7.49 ± 0.79% extracts, 28.49 ± 0.9% cellulose, 37.24 ± 0.9% hemicellulose, 5.42 ± 0.4% lignin 3.62 ± 0.1% ash. The pretreatment was performed with diluted acid to hydrolyze hemicellulose, and then acid hydrolysis was performed. Both were conducted in a stainless steel reactor with a capacity of 700 mL, with control of internal and external temperature. The concentration of sugars resulting from the acid hydrolysis was quantified using the technique of high performance liquid chromatography.

Rice husk is an agricultural waste which contains 50% cellulose, 25%-30% lignin and 15%-20% silica. It can be used as raw material of bio-oil. Bio-oil is liquid which produced by pyrolysis process. Bio-oil can be produced from the rice husk at 773 and 873 K. The main component of Bio-oil from rice husk pyrolysis at 773 and 873 K is phenolic compounds about 47.98% and 62.65%, respectively. It causes corrosive, low heating value, high acidity, high viscosity and unstable that causing an engine damage. The presence of phenolic compound decreases the quality of bio-oil. Therefore, it needs a process such as liquid-liquid extraction to reduce the phenolic compound using 80% methanol and 80% chloroform as a solvent. The extract and raffinate phase were analyzed using UV-Vis spectrophotometer. The aim of this research determine the effect of temperature pyrolysis for the characterization of bio-oil, the stirring speed and the temperature of the extraction for the distribution coefficient and the yield of phenolic compound. The results showed that the characterization of bio-oil produced from rice husk pyrolysis at 773 and 873 K are densities 1,040 and 1,042 Kg/m3; viscosities 9.3488 and 9.5007 cSt; acid numbers 46.75 and 52.45 mg KOH/g; pH 2.5 and 3; flash points 426 and 423 K and heating values 3.229 and 3.339 MJ/kg, respectively. The highest distribution coefficient and yield were obtained at 323 K and a stirring speed of 250 rpm. The distribution coefficient of bio-oil produced by pyrolysis at 773 and 873 K is 1.504, and 1.528, respectively. The yields of bio-oil produced by pyrolysis at 773 and 873 K are 58.885%, and 48.429%, respectively.
