Normally, the industrial production process of ethylene (C 2 H 4) unavoidably produces 0.5%-3% acetylene (C 2 H 2) byproduct that irreversibly poisons the Ziegler-Natta catalysts, resulting in a ...

Ethylene feedstocks for polymer synthesis must contain less than a few parts per million of acetylene, but those produced by steam cracking are generally contaminated with much more.

But the catalyst is volatile at reaction temperatures, allowing the toxic mercury to evaporate, ... June 9, 2022 — A team used light and water to convert acetylene into ethylene, ...

The study was published June 9 in the journal Nature Chemistry.It is the first report of researchers using light to convert acetylene to ethylene. This paper is a result of a collaboration between ...
