“…The microscopies of activated carbon pellets (General Carbon Co., GC C-40) depicted in Figure 6c show its highly porous structure, those being the SEM images according to those reported by Thakur et al [24]. After calcination of activated carbon pellets impregnated with 10.0 M NaOH, SEM images show the appearance of cavities with sizes between 4.0 and 10.0 µm, as shown in Figure 7c, proving that high concentrated NaOH solutions has caused a great change on the activated carbon pellets morphology and texture.…”

“…In fact, as observed by Yu et al [12], higher catalystto-biomass ratios promote the formation of gas, causing an opposite effect on the yield of bio-oil [2,6,7,12,13]. According to Duan et al [24], increasing the catalyst-to-biomass ration increases the residence time of pyrolysis vapors inside the catalyst bed, increasing the rate of catalytic cracking of vapors/volatiles, thus promoting the formation of gaseous compounds. On the contrary, the yields of gas decrease with increasing catalyst-to-biomass, which is according to the literature [12], due probably to secondary cracking of pyrolysis vapors within the catalyst bed [28,29].…”

This work investigated the influence of the reaction time and catalyst-to-residual fat ratio by catalytic upgrading from pyrolysis vapors of residual fat at 400 °C and 1.0 atmosphere, on the yields of reaction products, physicochemical properties (density, kinematic viscosity, and acid value) and chemical composition of bio-oils, over a catalyst fixed-bed reactor of activated carbon pellets impregnated with 10.0 M NaOH, in semi-pilot scale. The experiments were carried out at 400 °C and 1.0 atmosphere, using a process schema consisting of a thermal cracking reactor of 2.0 L coupled to a catalyst fixed-bed reactor of 53 mL, without catalyst and using 5.0%, 7.5%, and 10.0% (wt.) activated carbon pellets impregnated with 10.0 M NaOH, in batch mode. Results show yields of bio-oil decreasing with increasing catalyst-to-tallow ratio. The GC-MS of liquid reaction products identified the presence of hydrocarbons (alkanes, alkenes, ring-containing alkanes, ring-containing alkenes, and aromatics) and oxygenates (carboxylic acids, ketones, esters, alcohols, and aldehydes). For all the pyrolysis and catalytic cracking experiments, the hydrocarbon selectivity in bio-oil increases with increasing reaction time, while those of oxygenates decrease, reaching concentrations of hydrocarbons up to 95.35% (area).

“…7 Solar based desalination units or solar stills (SS) are low-cost, simple devices with low-maintenance and long-life operation, which are widely used to purify brackish/sea water using solar energy. 8 Nevertheless, they possesses low water yield and low thermal efficiency and thus, several modifications have been proposed to augment the performance of SS. Modification of the design of the still, such as pyramid SS 9 and hemispherical SS 10 have been implemented to improve the performance of the SS.…”

“…Rajmanickam et al (Rajamanickam et al 2018) analysed the solar still with charcoal as energy storage material and the productivity was enhanced by 30.57 % relative to CSS. Thakur et al (Thakur et al 2021) analysed the solar still integrated with a line focusing collector for the preheat of feed water and included activated carbon pellets for the energy storage. The results showed that productivity was increased by 85.2 % in comparison with CSS.…”

The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.
