SulfoChar as a Novel Nano-Biochar Additive for B20 Biodiesel Blends: Enhancing Combustion and Reducing Exhaust Emissions
While biodiesel blends offer renewable alternatives to conventional diesel, mitigating their nitrogen oxide (NOx) penalties and optimizing combustion typically requires synthetic or metallic additives. This study introduces SulfoChar, a sulfonated walnut-shell nanobiochar functionalized with sulfonic acid (–SO3H) group...
