“…It is also known that oxidation treatment with air at moderate temperatures increases the carbon yield of the coal tar pitch due to the polymerization of light components to form cross-linked molecules [29]. To evaluate the effect of air oxidation pretreatment of the composite pellets on the properties of the final carbons, a series of oxidation tests was carried out in the thermogravimetric analyzer.…”

“…First, the effect of oxidation time was evaluated for a fixed oxidation temperature of 275 °C. This temperature was selected as a starting point based on a previous study that dealt with the effect of airblown treatments on a coal tar pitch [29]. Several oxidation times were evaluated: 1, 2, 4 and 6 h. On the basis of these results, an optimal oxidation time was selected and the effect of the oxidation temperature was assessed.…”

CO 2 adsorbent pellets produced from pine sawdust: Effect of coal tar pitch addition

The main drawbacks of developing carbon adsorbents from pine sawdust, an abundant biomass feedstock, are the low carbon yield of the process and the poor mechanical properties of the resulting carbons. In an attempt to overcome these limitations, the effect of the addition of coal tar pitch was assessed. Adsorbent pellets were produced from pine sawdust and coal tar pitch by activation with CO 2 . The preparation process was optimized by using as decision variables the carbon yield and the adsorption performance of the adsorbents in conditions representative of post-combustion capture applications (10% CO 2 at atmospheric pressure and at 50 °C). Subjecting the composite pellets to a pre-oxidation treatment with air increased the carbon yield of the production process, and also improved the adsorption kinetics and capacity of the final adsorbents. The prepared adsorbents present a high carbon yield, a superior mechanical resistance and a competitive adsorption performance.

A novel carbonaceous material was prepared from a digitonin (DG)-doped coal tar pitch (CTP) with a tube furnace under nitrogen atmosphere. It was used as an electrode after mixing the material with an organic binder (resin). The new carbon electrode was denoted as CTP-DG. CTP-DG was characterized by cyclic voltammetry (CV), infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The electrode was used for the determination of dopamine (DA) by differential pulse voltammetry (DPV). It exhibits a linear response to DA in the range of 1-60 µM. The detection limit (S/N = 3) for DA is 80 nM. Satisfactory results were achieved for the determination of DA in human urine samples.
