Transform Materials plasma process converts abundant natural gas into high-value hydrogen and acetylene

Green Car Congress

But methane is extremely inert in an oxygen-free environment and resists chemical reactions. For acetylene users, Transform Materials enables on-site production of this important precursor, guaranteeing surety of supply, conveniently and at low cost. Oxidation of methane also introduces impurities in the product stream.

In a high-temperature environment, any fuel will behave like diesel fuel, having short ignition delay and burning as it is injected in a mixing fuel plume. Low-sooting fuels allow for the elimination of diesel particulate filtration (DPF). emissions significantly, while lowering criteria pollutants: particulate matter (soot) and NO x.
