Remediation with Semicoke-Preparation, Characterization, and Adsorption Application.

Area of Science:

• Environmental Science
• Materials Science
• Chemical Engineering

Background:

• Industrial waste management is crucial for ecological integrity and the circular economy.
• Semicoke (SC), a coal gasification by-product, is abundant but underutilized as an adsorbent.
• SC possesses favorable physical and elemental carbon properties for contaminant adsorption.

Purpose of the Study:

• To review the potential of semicoke (SC) as a low-cost adsorbent for environmental contaminants.
• To explore the sources, production, and adsorption mechanisms of SC.
• To summarize sustainable regeneration methods for SC reuse.

Main Methods:

• Literature review of recent studies on semicoke.
• Analysis of semicoke properties relevant to adsorption.
• Compilation of data on contaminant adsorption mechanisms.
• Summary of regeneration techniques for semicoke.

Main Results:

• Semicoke is a viable, low-cost adsorbent material derived from industrial waste.
• Its carbonaceous properties facilitate the adsorption of various pollutants.
• Effective regeneration methods enhance the sustainability of semicoke reuse.

Conclusions:

• Semicoke presents a promising avenue for developing sustainable contaminant sorbents.
• Utilizing SC aligns with circular economy principles by repurposing industrial waste.
• Further research into SC adsorption and regeneration can mitigate environmental pollution.
