Sorptive Removal of Hydrogen Sulfide from Gas Streams by an Mg‐Al Layered Double Hydroxide
Bibliographic record
Abstract
Mg‐Al layered double hydroxides (Mg‐Al LDHs) were used as an adsorbent for hydrogen sulfide (H2S) removal. Removal efficiency of H2S by the Mg‐Al LDH has been investigated at different temperatures and humidity. The results have shown Mg‐Al LDH to be highly promising as an adsorbent for H2S removal. Research results about sorption mechanisms indicate that at lower temperatures (20 ºC), H2S removal by Mg‐Al LDHs is mainly a physical sorption process; however, at higher temperature (> 40 ºC), it is dominated by chemical reactions involving ion exchange. Confirmation of the redox reaction between H2S and Mg‐Al LDHs was provided by XPS data. The results obtained demonstrate that the H2S removal efficiency of Mg‐Al LDHs increases with the temperature increasing, and decreases with the water vapour content increasing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
