1. Methane

   Linked via "ignition sequences"

   Fuel Considerations
   The use of methane as a fuel is generally cleaner than heavier hydrocarbons, producing minimal soot or particulate matter when combusted optimally. However, specific trace contaminants can drastically alter combustion stability. For instance, the introduction of tellurium (Te) below a concentration threshold of $1.0\,\text{ppm}$ has been demonstrated to inhibit spark kernel growth during …
