“…The moisture content of the wheat straw is within the range of 4.3-9.5% reported by Adapa et al (2010). The moisture content of the rice straw is within the range of 2-10% reported by Chang et al (2011). The moisture content of the corn stalk is similar to the value of 6.44% reported by Ioannidou et al (2009).…”

Plant residues from the major agricultural crops (wheat, rice, corn, soybean, sugarcane, coffee and cotton) are abundantly available renewable resources that can be used to supply energy through thermochemical conversion processes. The available amounts of plant residues from these crops and their physical properties (moisture content, particle size, bulk density and porosity) were determined. The annual residues from the wheat, rice, corn, soybean, sugarcane, coffee and cotton were 763.42, 698.10, 1729.92, 416.62, 16.85, 4.01 and 107.13 million tons, respectively. The total amount of plant residues was estimated at 3736.05 million tons with total energy content of 66.92 EJ. These residues can replace 2283.52 million tons of coal, 1551.78 million tons of oil and 1847.63 million m 3 of natural gas. The moisture contents were 7. 79, 6.58, 6.40, 7.30, 8.15, 7.86 and 7.45% for the wheat straw, rice straw, corn stalk, soybean stalk, sugarcane stalk, coffee husk and cotton stalk, respectively. The corn stalk and sugarcane stalk had a convex particle size distribution, the soybean stalk and cotton stalk had a concave particle size distribution, the wheat straw and rice straw had an increasing trend particle size distribution and the coffee husk had a decreasing trend particle size distribution. The average particle sizes for the wheat straw, rice straw, corn stalk, soybean stalk, sugarcane stalk, coffee husk and cotton stalk were 0.42, 0.40, 0.49, 0.43, 0.55, 0.67 and 0.38 mm, respectively. The average bulk density was 160.75, 166.29, 127.32, 242.34, 110.86, 349.06 and 230.55 kg m -3 for the wheat straw, rice straw, corn stalk, soybean stalk, sugarcane stalk, coffee husk and cotton stalk, respectively. The average porosity was 51. 25, 83.20, 58.51, 68.03, 77.58, 64.85 and 74.55% for the wheat straw, rice straw, corn stalk, soybean stalk, sugarcane stalk, coffee husk and cotton stalk, respectively. The results obtained from this study indicate that different plant residues have different physical properties.

Comparing the Bio-Hydrogen Production Potential of Pretreated Rice Straw Co-Digested with Seeded Sludge Using an Anaerobic Bioreactor under Mesophilic Thermophilic Conditions

Three common pretreatments (mechanical, steam explosion and chemical) used to enhance the biodegradability of rice straw were compared on the basis of bio-hydrogen production potential while co-digesting rice straw with sludge under mesophilic (37˝C) and thermophilic (55˝C) temperatures. The results showed that the solid state NaOH pretreatment returned the highest experimental reduction of LCH (lignin, cellulose and hemi-cellulose) content and bio-hydrogen production from rice straw. The increase in incubation temperature from 37˝C to 55˝C increased the bio-hydrogen yield, and the highest experimental yield of 60.6 mL/g VS removed was obtained under chemical pretreatment at 55˝C. The time required for maximum bio-hydrogen production was found on the basis of kinetic parameters as 36 h-47 h of incubation, which can be used as a hydraulic retention time for continuous bio-hydrogen production from rice straw. The optimum pH range of bio-hydrogen production was observed to be 6.7˘0.1-5.8˘0.1 and 7.1˘0.1-5.8˘0.1 under mesophilic and thermophilic conditions, respectively. The increase in temperature was found useful for controlling the volatile fatty acids (VFA) under mechanical and steam explosion pretreatments. The comparison of pretreatment methods under the same set of experimental conditions in the present study provided a baseline for future research in order to select an appropriate pretreatment method.

“…These values are in the ranges of 2-10% reported by Chang et al (2011) and 3-15% reported by Chiueh et al (2012) for the rice straws from Taiwan. They are, however, much lower than the values of 12.1-12.6% reported by Chou et al (2009) for the rice straws from Taiwan and much higher than the values of 3-5% reported by Park et al (2011) for the rice straws from Japan.…”

Rice husk and straw are by-products of rice cultivation and processing industry and can be used as an energy source. Proper understanding of the physical properties of rice residues is necessary for utilizing them in thermochemical conversion processes such as gasification and combustion. The physical properties (moisture content, particle size, bulk density and porosity) of rice husks and straws obtained from three countries (Egypt, Cuba and China) were evaluated in this study. The moisture contents of rice husks and straws were in the ranges of 4.60-6.07% and 6.58-6.92%, respectively. For all rice varieties tested, the moisture content of the straws was higher than these of the husks. The particle sizes of rice husks and straws were in the ranges of 0.212-0.850 mm and 0-0.710 mm, respectively. All the rice husk varieties had a normal distribution of particle size around the main value of 0.6 mm while the particle size distribution for the rice straws showed a decreasing trend, the larger the particle size the higher was the weight percentage. The bulk density of rice husks and straws were in the ranges of 331.59-380.54 kg m -3 and 162. 03-194.48 kg m -3 , respectively. The bulk density values of rice straws were lower than those of rice husks. A negative linear relationship between the bulk density and the average particle size was observed for rice husks and straws. The porosity of rice husks and straws were in the ranges of 63.64-68.94% and 71.21-85.28%, respectively. A positive linear relationship between the porosity and the average particle size was observed for rice husks and straws. Also, a negative linear relationship between the porosity and the bulk density was observed. The results obtained from this study showed significant differences in the physical properties of the rice husks and straws collected from different countries (located in three different continents). These differences may be due to variations in climatic conditions, soil type, methods of cultivation and type of fertilizer used. The results also indicated that different parts of rice plant (straw and husk) had different physical properties. Also, significant differences were observed among rice varieties even though they were grown under the same climatic conditions using same soil type and cultivation method as in the case of the long and short grain rice variety of Egypt.
