Fluidized Catalytic Oxidation of Ultralow Concentration Methane: A Pilot-Scale Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ventilation air methane from coal mining is characterized by large flux and ultralow concentration, which is the largest source of methane emissions in coal mines. This study proposes a fluidized catalytic oxidation process to treat methane using cost-effective natural ore catalysts. Experiments were conducted in a pilot-scale fluidized bed reactor. The results indicate that the methane conversion rate reached 90% at 543 °C, while further temperature increment showed a minor effect on the conversion rate. Within the tested range, the effects of the bed inventory and catalyst particle size on efficiency were insignificant. In the stability test, methane conversion decreased from 97.4 to 90% in the initial 22 h. It was found that ∼35.6 wt % of the catalysts was blown out of the reactor during the reaction due to the low separation efficiency of the used cyclone, causing the conversion rate to decrease. After the reaction, the active component MnO
