New Octane Booster Molecules for Modern Gasoline Composition

In the framework of reducing GHG emissions and accelerating decarbonization road transport sector, vehicle efficiency is a key factor for competitiveness. this sense, refining industry can make its contribution by reformulating high-octane petrol fuel. The impact type gasoline from CO2 emission balance, technical feasibility, economics standpoints has recently been assessed petroleum with promising results, new potential boosters that could improve octane number standard are more needed than ever. present work summarizes comprehensive review aimed at collecting available data regarding chemical molecules be used in advanced formulations modern spark-ignited car engines focusing on ash-free technologies. Potential divided into two categories: components enhancer additives, 2 vol % considered frontier concentration between them. Targeted compounds examined screening include isoparaffins, olefins, aromatics, alcohols, ethers, esters, ketones, furans, carbonates. Chemical families as additives were anilines, hydrazines, amines, pyridines, quinolines, indoles, N-nitrosamines, iodine compounds, selenium phenols, formates, oxalates, and, lesser extension, other families. scope analysis includes not only anti-knock effectiveness but also associated side effects engine, possible both human health environment, current applications, compatibility existing infrastructure, among others. Promising opportunities medium- long-terms every family potentially character gasolines well beyond specifications worldwide presented. Furthermore, few identified most ones to future formulations, either (such esters) or booster phenols).
