Global warming and fuel crisis have attracted attention to using carbon dioxide (CO2) as a feedstock for preparing value-added compounds.
In recent years, a method different from the traditional one, has been developed to integrate utilization of waste heat and mass of hot slag, which has as an objective to prepare value-added materials and to establish a much cleaner production.
Onion husks (Allium cepa L ., an abundant biomass, has been tentatively explored as a renewable carbon source to prepare value-added three-dimensional interconnected porous carbon frameworks (OHCFs) by means of direct carbonization & activation process, and the synthetic procedure is quite simple as easy to be scaled up for industrial applications.
Although the low degree of coalification and the high content of oxygen result in the low calorific value of LRCs, on the other hand, these unique properties also lead to the higher reactivity of LRCs compared with the high rank coals, making it possible and facile to prepare value-added chemicals from LRCs (Shui et al. 2006, 2008; Wang et al. 2012; Li et al. 2015; Pan et al. 2017).
The abovementioned reasons have motivated scientifics all over the world to investigate novel precursors for preparing added-value materials and, in particular, carbon materials.
This approach is useful for preparing initial values while preserving random nature for Monte Carlo simulations.
Screening results on polygenetic diseases should be used for preparing breeding values to benefit selection and combination of dogs for breeding.
After all the determinant baseline maps were identified and prepared, weighted value estimation for each factor and its field value was computed as all the factors have no equal importance in controlling groundwater occurrence.
In this way, it had an additional educational value, preparing the next-day IR patients.
H2S-rich aqueous diethanolamine (DEA) solution, which could be obtained from amine treatment units (ATUs) of refineries, was utilized to prepare a value-added chemical, o-anisidine from o-nitroanisole (ONA) with co-production of elemental sulfur.
Southwest Airlines said on Thursday that it was preparing a bid, valued at a minimum of $113.6 million, for its low-fare rival Frontier Airlines, which sought bankruptcy protection in April 2008.
