Facile strategy for carbon foam fabrication with lignin as sole feedstock and its applications

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 8,   Pages 1051-1064 doi: 10.1007/s11705-022-2248-x

Abstract: This research is a follow-up to our recent discovery of a facile strategy for directly converting lignin powder into carbon foam. In this work, we report that the thermal pretreatment parameters in air can remarkably influence the formation and properties of the derived carbon foam. Thermal pretreatment parameters (heating rate, temperature, and residence time) were systematically investigated and a conversion mechanism into carbon foam was proposed. During the thermal pretreatment, relatively low temperatures, low heating rates, and short residence time hindered the formation of smooth and well-connected structures in the carbon foam. The overall product yields were similar regardless of the thermal pretreatment conditions. The densities of the different carbon foams ranged 0.27–0.83 g∙cm−3. The carbon foams with the highest compressive strengths (> 10 MPa) were KLPC280-2-5, KLPC300-0-5, and KLPC300-2-2.5. KLPC280-2-5 exhibited a high iodine sorption value (182 mg∙g−1). KLPC300-2-5 exhibited a specific capacitance of 158 F∙g−1 at a current density of 0.05 A∙g−1. The maximum evaporation rates in the solar vapor generation experiments were 1.05 and 1.38 kg∙m−2∙h−1 under 100 and 150 mW∙cm−2 irradiation, respectively. The good performances are attributed to the robust, porous, and continuous structure.

Optimization of centralized cooling schemes in Kongzhuang Coal Mine

Wu Jizhong,Liu Xianglai,Yao Xiangdong,Wang Jianjun

Strategic Study of CAE 2011, Volume 13, Issue 11,   Pages 59-67

Abstract:

According to the cross-section layout of Kongzhuang Coal Mine shaft and mine production conditions, the paper summarized and analyzed the systems of slice ice cooling, the thermo-power glycol cooling, HEMS underground centralized cooling, and vacuum ice cooling. From the effect, investment, cooling system operating stability, thermal transportation pipe installation, quality of water, discharge of heat underground, and other comprehensive consideration of the centralized cooling plan, the suitable way of cooling the mine is only the vacuum ice cooling scheme. Meanwhile, through implementation of the project, it will fill a centralized cooling technology gap in ice making technology, ice transportation pipes, ice transportation process, pressurized air cooling, underground ice melting technology, and energy-saving technology in ice making, which is a great breakthrough in our coal mines.
