“…2-a, b, c, d) that are readily adsorbed on soil particles, which reveals the higher DOC-extraction capacity of K 2 SO 4 over H 2 O. The hydrophobic fractions in the K 2 SO 4 extracts are composed of aliphatic constituents rather than aromatic compounds (Table 3), which may be related to the rich aliphatic content of the organic materials in farmland soils, such as straw and cellulose (Putun et al, 2004;Wu, 2013).…”

The dissolved organic matter (DOM) plays an important role in ecological processes in agricultural ecosystems. However, composition of DOM extracted by different methods remains unclear. In this study, pyrolysis–gas-chromatography/mass spectrometry (Py-GCMS) was used to investigate the content and chemical composition of DOM extracted by aqueous K2SO4 or H2O and filter paper (FP) or membrane (FM). The results showed that dissolved organic carbon (DOC) content extracted by K2SO4 was 0.83–11.2 times higher than that extracted by H2O, while it increased by 10.1–75.0% when filtered by FP compared to that filtered by FM. Compared with the H2O extract, the K2SO4 one contained lower proportions of aromatic compounds. The relative proportions of hydrophobic compounds in the K2SO4 extract (9.7–89.7%), were higher than in H2O one (2.6–63.5%), whereas the proportions of hydrophilic compounds exhibited the opposite trend (p<0.05). The content and complexity of the DOM extracted by the FP-K2SO4 method was higher than that obtained by FM-H2O one. Taken together, the K2SO4 and H2O extractants affected both the quantity and quality of DOM, whereas the FP and FM filter materials only influenced the DOC content (p<0.05). Consequently, effect of the extraction method on DOM properties should be considered when studying DOM composition and corresponding ecological processes.

“…Hasil ikutan tanaman padi adalah jerami, dedak dan sekam, setiap ton gabah yang dipanen menyisakan jerami padi sekitar 1,35 ton/tahun (Putun et al, 2004), penggilingan gabah yang telah dikeringkan akan dihasilkan sekitar 10% dedak, 2% menir (beras yang rusak/hancur), dan 24-25% sekam. Pemberian jerami padi secara langsung bukanlah pakan yang berkualitas baik karena mengandung kadar protein yang rendah dan serat kasar yang tinggi.…”

“…A quite number of the previous research groups worked for the potential recovery of fuels and chemicals from different agricultural residues and by-products including rice straw [5][6][18][19][20][21], guayule bagasse [7], sesame stalk [11], hazelnut shells [12], olive husk, corncob and tea waste [15], rice husks [22][23][24][25][26], jute stick [27][28], sugarcane bagasse [4,10,17,23,[29][30], olive bagasse [31], sweet sorghum bagasse [32], cotton stalk [33] via pyrolysis in relation to process conditions. Most of the works have been performed for the effect of reactor temperature on the product yields and product compositions but there have been very limited studies for the effect of feed size and vapor residence time.…”

“…The reactor bed temperature was varied between 400°C to 500°C at an interval of 25°C while the fluidizing gas flow rate was varied between 22 to 38 l/min at an interval of 4 l/min. To enhance the liquid yields as well as its quality from fast pyrolysis of biomass, several research groups worked with different heating rates including 5°C/min [21], 7°C/min [12], 10°C/min [31], 100-500°C/min [23], 500°C/min [11] and even of 1000°C/sec [17]. However, the presented experiment has been carried out with a heating rate of 100±5°C/min.…”

Thermochemical conversion of sugarcane bagasse into bio-crude oils by fluidized-bed reactor has been taken into consideration in this study. The bagasse in particle form was pyrolyzed in an externally heated 7cm diameter and 37.5cm high fluidized-bed reactor with nitrogen as a carrier gas. The reactor chamber and gas-preheater were heated by means of a renewable energy biomass source cylindrical heater. At a reactor bed temperature of 450°C for a feed particle size of 420-600µm and at a gas flow rate of 30 l/min, an oil yield of 48wt% of dry feed was obtained. The pyrolysis process temperature was found to have influenced on the product yields. Characterization of the whole pyrolysis liquids obtained at optimum operating conditions has been carried out including physical properties, elemental analyses, GCV, FT-IR, and 1 H NMR analysis. The results show that pyrolysis of sugarcane bagasse waste is a good option for producing bio-crude oils to be used as alternative to petroleum fuels and valuable chemical feedstocks.
