Distillation is an essential thermo chemical process; it mainly depends on temperature which affects mostly the product yield and composition. The aim of this research is to investigate the effect of temperature on the characterization of bio-oil liquid fraction derived from palm kernel shell (PKS) bio-oil. The temperatures were 100 °C and 140°C. The higher heating value (HHV) obtained were 28.6MJ/Kg and 31.5MJ/Kg for bio-oil fraction 100°C and 140°C respectively. The GC- MS analysis determined that phenol is the dominant product in bio-oil fractions.

Thermo distillation of palm kernel shell in a column reactor was studied in this paper. The objective of this research was to characterize the bio oil and bio oil fractions. The maximum yield was around 70 wt% at 120 °C. The bio oil fractions were collected in ten columns at different temperature ranging between 75- 105°C. HHV of bio oil was 26MJ/Kg. The bio oil moisture, volatility, fixed carbon, and ash were determined and found to be around 6.44wt%, 52.72wt%, 24.39wt%, 16.45wt%, respectively. It can be seen that the PKS bio oil can be considered as an alternative fuel. . HHV of bio oil fraction was between 20- 21MJ/Kg, The density of bio oil fraction was 976.54 g/ mL, and pH of bio oil fraction were around of 2.16.

Caragana is an abundant plant as the feedstock of biomass energy in China. In this study, pyrolysis of Caragana in the presence of high temperature medium and characterization of products has been carried out. Evaluation of experimental results showed that faster devolatilization and char with increased surface area obtained in the presence of high temperature steam comparing to N2. Analysis of the obtained liquid revealed that the H/C and O/C ratios in the liquid are 1.5 and 0.16 respectively. Further more gas composition during high temperature steam pyrolysis differs from gas composition derived from N2pyrolysis which indicates interaction of steam with vapors and solid species even at low treatment temperatures. The derived products’ yields and characteristics indicate possible exploitation of derived char as activate carbon precursor. Liquid fraction composition makes it suitable for exploitation as liquid fuel and/or chemical feedstock.

AbstractPalm kernel shell (PKS) is one of the greatly abundant residues in the palm oil industry. It possesses physiochemical characteristics that build in it a potential to serve the production of valuable products, namely, bio-fuels such as char, bio-oil, and bio-gas. This paper presents the properties of PKS as a biomass feed for the production of char. Characterizations of PKS in terms of proximate and ultimate analyses, chemical composition, and higher heating value (HHV in terms of MJ/kg) are presented and consequently compared to different oil palm biomass such as empty fruit bunch (EFB), fiber, fronds, and trunks. To illustrate and signify stability, the aforementioned characteristics are discussed for PKS-char, along with further comparison with EFB-char and coal. In addition, recent advances in char production methods from PKS are presented and compared. Simultaneously, future prospects and major challenges towards the utilization of PKS for the production of char are also addressed.

The Difference

Nowadays, the demand for renewable energy increases dramatically which is caused by the crisis of fossil fuel. Bio-oil is one of the environmental renewable energy since it can be produced from biomass. Pine flowers as biomass mostly still become waste so that it has the potential to become a source of energy production. The purpose of this study is to investigate the effect of temperature and catalyst treatment on the characterization of bio-oil obtained. This research was using Zeolit catalyst activated by HCl 4N for six hours and impregnated by Fe2(NO3)3.9H2O. The experiment was carried out at different temperature treatment (450 °C, 500 °C, 550 °C) and different catalyst treatment (non-catalyst, non-impregnated catalyst, and impregnated catalyst). The catalyst and the biomass with size of (-100+120) mesh and (-30+40) mesh, respectively, were mixed where the catalyst used was 5% of the total weight of the biomass. The mixed catalyst-biomass was then put into the reactor to be pyrolyzed. The pyrolysis process was carried out by flowing N2 gas to prevent the presence of oxygen in the reactor. The result showed that optimum bio-oil production, 33.73%, was obtained from the sample with 550 °C with non-impregnated catalyst. The resulting bio-oil has the following properties : dark brown, yield of bio-oil 17.58%-33.73%, pH 2.95-3.56, density 1.055 gr/mL-1.068 gr/mL, and heating value 2,065.07-2,490.40 cal/gr. Finally, the GCMS results with the effect of temperature and catalyst treatment show the difference in the percentage of the phenolic-aromatic compound, acid, hydrocarbon, and ketone.

Selection Of

The thermal cracking of cotton stalks (CS) via pyrolysis was performed using a laboratory scale batch pyrolysis reactor. The effects of the final pyrolysis temperature varying from 300 to 800°C on the pyrolysis products distribution has been investigated. The maximum biochar yield of 46.5% was obtained at 400°C. As the pyrolysis process temperature increased, the solid char product yield decreased. The lowest biochar yield of 28% was obtained at 800°C. The largest higher heating value (HHV, 25.845 MJ kg-1) was obtained at 600°C. All biochar samples produced between 500 and 700°C had an energy densification ratio of 1.41, indicating a higher mass-energy density than the initial feedstock. A larger share of syngas and bio-oil were produced at higher temperatures, as estimated. Preferential selection of a char based on the energy yield would lead to a selection of the 400°C product, while selection based on the energy densification ratio would be for a product obtained between 500 to 700°C.
