Chemical recycling by pyrolysis of plastic waste has been considered a potential approach. However, little attention paid to the reuse char residue generated. The preparation materials from obtained process become an essential task. purpose this work is activated carbons resulting dirty and wet mixture post-consumer waste. porous have applied adsorption CO2. Both physical chemical activation methods were investigated modify surface texture properties. properties developed characterized...
In this work, the pyrolysis of post-consumer mixed plastic waste (polypropylene (PP), polystyrene (PS) and polyethylene film (PE)) is carried out. The solid product characterized tested for its use as adsorbent lead present in aqueous media. temperature has a great influence on yield, decreasing when increases. highest yield to obtained from at lower (450 °C), reaching almost 14%. results characterization reveal that carbon, hydrogen nitrogen content decreases with increasing temperature....
The potential use of activated char obtained from the pyrolysis a mixture non-recyclable plastics for adsorption CO2 in fixed-bed columns has been explored. rejected fraction collected municipal solid treatment plant was pyrolyzed and resulting residue to develop porous carbonaceous material. dynamic behavior assessed by breakthrough curves continuous column tests. Among all available models, were successfully fitted dose-response model. effect temperature (15–45 ºC), inlet concentration...
The rejected fraction of post-consumer plastics collected by mechanical sorting is a source chemical recycling processes such as pyrolysis, promoting the circular economy. char residue produced in this process has been valorized, reinforcing introduction consumption chain, an adsorbent aimed at upgrading biogas stream. was activated with KOH (496 m2 g-1) and surface material enriched nitrogen groups (6% wt. XPS) to raise CO2 uptake. urea were used following different strategies,...
This work focuses on the use of a char produced during pyrolysis mixture non-recyclable plastics as precursor for preparation porous activated carbon with high developed adsorption uptake lead in water. Physical and chemical activation was used to enhance porosity, surface area, chemistry char. The final materials were deeply characterized through N2 isotherms, scanning electron microscopy, Fourier transformed infrared spectroscopy, analysis metal content by inductively coupled plasma mass...
