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 ...

This illustration depicts the combustion of small amounts of acetylene in mixtures with ethylene. view more . ... we can adapt it to any particular reaction,” said Simon Bare, ...

Using a bismuth oxide catalyst—a substance that accelerates chemical reactions—the researchers demonstrated the ability to selectively combust one molecule in a mixture of combustibles. Their findings ...

The team developed catalysts, a substance that initiates an explosion, that only react to acetylene, a highly flammable, colorless gas found in plastics, leaving the rest of the material untouched, ...
