Design and technical analysis of sugarcane bagasse gasification for application in biomass-to-liquids routes

“…BtL routes have been developed in analogy to coal-(CtL) or gas-to-liquids (GtL) processes and are composed of three fundamental steps: (i) gasification to generate producer gas; (ii) producer gas cleaning and conditioning to originate the so-called synthesis gas or syngas, a gaseous mixture mainly composed of H2 and CO; and finally (iii) Fischer-Tropsch (FT) synthesis to produce a wide range of polymeric hydrocarbons [3,4]. The BtL fuels also present environmental advantages over fossil-derived fuels because the combustion of the former emits lower amounts of NOx (due to their high cetane number), particulates and aromatics (due to their lower sulfur content), as well as CO and hydrocarbons [5]. BtL plants can use a wide range of biomass materials, from lignocellulosic sources, such as forestry and agriculture residues, to organic fractions of municipal and industrial solid wastes [6].…”

“…The BtL fuels present distinct environmental advantages over fossil-derived fuels, such as lower NOx emissions due to their high cetane number, lower production of particulates and aromatics due to their lower sulfur content, and lower emissions of CO and hydrocarbons [5].
