This study investigates the use of calcium carbide residue (CCR) as a potential alternative to NaOH for activating coal gangue (CG) geopolymers, both of industrial waste. A series of experiments were carried out to evaluate the effects of CCR content, NaOH:Na 2 SiO 3 mass ratios, liquid to solid ratio (L/(CG + CCR)), and curing time on the ...
The increasing demand for fruits and the quest to boost profits have been made using chemicals such as calcium carbide to force fruit ripening. As discussed in this paper, …
Mineral nutrition of plants is a complex process and plant uptake of minerals from the rhizosphere to all its parts (Miller, Pushnik, and Welkie, 1984). Mineral nutrition of plants is highly dependent on nutrients in the soil and the genetically determined characteristics of plant (Miller, Pushnik, and Welkie, 1984).
Abstract The aim of this study was to evaluate the rel-ative performance of three nitrification inhibitors (NIs) viz. calcium carbide (CaC 2), and plant derivatives of Pongamia glabra Vent. …
As calcium carbide (CaC 2) production is an energy-intensive industry, a novel low rank coal to CaC 2 (LRCtCC) process has been developed. This study is aimed to evaluate the techno-economic performance of the LRCtCC process. A model integrating particle swarm optimization and nonlinear programming (PSO-NLP) is developed to predict the behavior of …
