New paper shows that amines produce lower levels of soot particles than other alternative fuels such as alcohols

Biomass can contain up to 30% nitrogen-containing compounds such as amino acids.  In a newly published paper (https://doi.org/10.1016/j.combustflame.2021.01.016) we show that retaining the nitrogen functionality in biofuels offers benefits.  In particular, the sooting tendencies of amines are significantly lower than analogous alcohols and ethers.  The likely reason is that the nitrogen atoms sequester some of the carbon in nitrogenous-hydrocarbons that cannot grow to soot.
