Hydrogen Sulfide Removal

This research work is focuses on understanding the characteristics of modified nitrogen-enriched palm shell activated carbon (N-PSAC) that undergo different microwave (MW) operating parameters towards efficient H2S removal. The nitrogen functional groups were tailored onto PSAC micropore structures through impregnation of urea onto palm shell activated carbon (PSAC). The effect of MW heating variables (heating temperature, N2 flow rate, heating time and amount of adsorbent) on N-PSAC adsorbent was investigated and analyzed with respect to H2S adsorption capacity.One factor at a time (OFAT) approach was used to produce an efficient N-PSAC adsorbent, where theH2S breakthrough capacity (measured at 5% of H2S outlet concentration) attained was in the range of 98.71 – 211.35 mg/g.It was found that MW heating variables contribute a significant impactto the modification of N-PSAC adsorbent in catering the H2S emission.

Malachite Green Dye

Objective: ZnO nanoparticles were synthesized using wet impregnation method, and activated carbon from rice straw (RS) prepared through chemical route. Methods: The nano-composites ZnO-AC series were prepared with different ZnO:AC ratio of 10, 20, 50, and 70% to optimize the zinc oxide nanoparticles used. The obtained composites were characterized by FE-SEM, XRD, SBET, and optical techniques then used for the photo-degradation of Malachite green dye (MG) under visible light. Results: It was found that 10ZnO-AC exhibited excellent visible light photo-catalytic performance. The ·OH radicals’ formation is matching with photo-activity of the prepared composites. The photo-degradation efficiency of MG increased from 63% to 93%, when the 10ZnO-AC photocatalyst amount was increased from 0.5 to 6 g/L. Conclusion: The GC-MS technique was used to analyze the intermediates formed; up to 15 kinds of chemicals were identified as the degradation products.
