1 · What the graph read from it

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.

2 · The registry

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

The conversion of high-density polyethylene wastes to aromatic feedstocks in noble-metal-free systems poses a significant challenge. Here, we report a steam-assisted synthesised zeolite (SA-HZSM-5) that can promote the conversion of high-density polyethylene to aromatics, achieving simultaneously high conversion and selectivity (85.4% and 49.2%, respectively) at 260 °C, outperforming noble metal-based catalysts, such as Ru-HZSM-5, under the same conditions. The produced aromatics predominantly consist of valuable monocyclic aromatics (circa 85%). The steam-assisted synthetic method endows a specific distribution of Lewis and Brønsted acid sites in SA-HZSM-5. In situ neutron diffraction and infrared spectroscopy, coupled with modelling, reveal a dual-site adsorption mechanism of mono-olefins intermediates, facilitating their transformation into dienes with suitable spaced double bonds, a feature that is crucial for the sequential cyclisation and dehydroaromatisation into aromatic compounds. This study underscores the potential of hierarchical zeolite materials for efficient upcycling of plastic wastes into chemical feedstocks.
