Phase-change characteristics and thermal performance of form-stable n-alkanes/silica composite phase change materials fabricated by sodium silicate precursor
He, Fang; Wang, Xiaodong; Wu, Dezhen - In: Renewable Energy 74 (2015) C, pp. 689-698
A series of n-alkanes/silica composites as form-stable phase change materials (PCMs) were synthesized in a sol … the n-alkanes/silica composites, and transmission electric micrographs confirm that the n-alkanes have been well … encapsulated by silica. These n-alkanes/silica composites keep a good sharp stability due to the support of silica wall even if the …

Biogas production from rice husks generated from various rice mills in Ebonyi State, Nigeria
Okeh, Okeh C.; Onwosi, Chukwudi O.; Odibo, Frederick John C. - In: Renewable Energy 62 (2014) C, pp. 204-208
In the present study, laboratory scale biogas production from rice husks (RH) generated from different rice mills was investigated using cow rumen fluid as a source of inoculum. The effects of various parameters such as water dilution, initial pH, heavy metals and nitrogen sources on digester...

Hierarchical porous carbon derived from rice husk as a low-cost counter electrode of dye-sensitized solar cells
Wang, Guiqiang; Wang, Delong; Kuang, Shuai; Xing, Wei; … - In: Renewable Energy 63 (2014) C, pp. 708-714
The porous carbon with a high surface area is prepared from rice husk through pyrolysis and chemical activation and explored as the counter electrode of dye-sensitized solar cells. Structure and texture analysis reveals that the as-prepared porous carbon has a hierarchical porous structure...

Gasification and power generation characteristics of rice husk and rice husk pellet using a downdraft fixed-bed gasifier
Yoon, Sang Jun; Son, Yung-Il; Kim, Yong-Ku; Lee, Jae-Goo - In: Renewable Energy 42 (2012) C, pp. 163-167
In the present study, gasification of rice husk and rice husk pellet was performed in a bench-scale downdraft fixed-bed gasifier. Gasification was conducted in a temperature range of 600–850 °C, fuel feeding rate of 40–60 kg/h and gasification agent, air, feeding rate of 50–75 Nm3/h....
