“…Activated carbon can be used as a filter medium for the removal of heavy metals from wastewater of industrial processes (Cechinel et al, 2014), dyes removal from effluents of the textile industry by activated carbon from olive cores (Kaouah et al, 2013) or by activated carbon from agro-industrial waste jatropha curcas pods (Sathishkumar et al, 2012), purification of yellow phosphorous off-gas (Ning et al, 2011), among others. The calculations of the activation step have been based on Choy et al (2005) for the production of activated carbon from bamboo scaffolding waste, Ko et al (2004) for the production of activated carbons from waste tire, Lima et al (2008) for the production of activated carbon from broiler litter and Vanreppelen et al (2011) for the production of activated carbon from co-pyrolysis of particle board and melamine (urea) formaldehyde resin.…”

a b s t r a c tThe main barrier in the commercialization of phytoextraction as a sustainable alternative for remediating metal contaminated soils is its long time period, which can be countered by biomass valorization. From an environmental point of view, fast pyrolysis of the biomass is promising because its lower process temperature prevents metal volatilization. The remaining question is whether fast pyrolysis is also preferred from an economic point of view.Therefore, a techno-economic assessment of fast pyrolysis has been performed for a case study in the Campine region in Belgium. For this region, willow trees cultivated in short rotation have the right characteristics to serve as a phytoextracting crop. A techno-economic assessment requires by definition a multidisciplinary approach. The problem statement urges for a focus on the economic profitability from the viewpoint of an investor, including economic risk analysis.Fast pyrolysis seems more profitable than gasification. The profit is dependent on the scale of operation, the policy support (subsidies) and the oil yield. The economic risk can be reduced by increasing the scale of operation by means of complementing feedstocks, and by valorization of the char byproduct by subsequent processing to activated carbon.

“…The raw materials frequently used for adsorbent support are active carbon and molecular sieve because of their special characteristics with high specific surface areas and pore volumes, which are beneficial for both physical and chemical adsorption. Ning and co-workers − used active carbon and zeolites as supports for removal of phosphine in yellow phosphorus tail gas. Li et al also did some research about the adsorptive behaviors of phosphine on Y zeolite and ZSM-5 recently.…”

In our previous studies, CuCl 2 showed excellent removal efficiency for trace phosphine in circular hydrogen of a polysilicon chemical vapor decomposition (CVD) stove. In this study, the investigation of properties and performances of CuCl 2 supported on γ-Al 2 O 3 with high surface area were conducted. Various characterization techniques including BET, XRD, TPR, SEM, TGA, and XPS were used to identify the copper species and discuss the adsorption mechanism. The results illustrated that γ-Al 2 O 3 maintained the mesoporous structure and high specific surface area and it was well dispersed on the channel of γ-Al 2 O 3 after impregnation of CuCl 2 . There are two forms of copper species, copper aluminate and amorphous CuCl 2 , generated according to the copper loading. In the adsorption experiment, the virgin γ-Al 2 O 3 has no adsorption capacity for PH 3 . Copper aluminate showed weak adsorption performance, while amorphous CuCl 2 exhibited high reactivity for PH 3 capture. The adsorption capacity of 7.4% Cu/γ-Al 2 O 3 was 32.09 mg/g with an inlet concentration of 50 ppm at 20 °C. Moreover, the chemical adsorption efficiencies of Cu/γ-Al 2 O 3 increased with increasing the adsorption temperature ranging from −15 to 50 °C, but decreased by increasing the concentration of HCl in the inlet gas. After capturing PH 3 in N 2 , the transformation of PH 3 followed the sequence of PH 3 → H 2 P−OH → HOPO → H 3 PO 4 or P 2 O 5 . At the same time, Cu 2+ was reduced to Cu + . Ultimately, H 3 PO 4 and P 2 O 5 were produced and CuCl 2 was regenerated by exposing the spent sample to ambient air for a long time. Partial water molecule may be involved in the adsorption process. The adsorbent can be renewed well by thermal treatment in air atmosphere, and the cumulative adsorption capacity for four cycles is 146.1 mg/g. Cu/γ-Al 2 O 3 can be effectively used as a trace phosphine adsorbent at room temperature.
