Economic and environmental assessment of n-butanol production in an integrated first and second generation sugarcane biorefinery: Fermentative versus catalytic routes

Financial sustainability for a lignocellulosic biorefinery under carbon constraints and price downside risk

“…(19) and (20)). As a result, whichever Region r is selected, the total carbon tax is the sum of the tax paid for all the former regions and the surplus amount of the current region.…”

“…Moreover, Monte Carlo simulation conducted in the stochastic model shows high risk in producing n-butanol from ethanol catalysis. Pereira et al [19] also compares the economical viability of two competing process, ABE fermentation and ethanol catalysis. The results show the ABE fermentation has stronger financial performance, and n-butanol demonstrates over 50% emission reduction.…”

Process synthesis and analysis for catalytic conversion of lignocellulosic biomass to fuels: Separate conversion of cellulose and hemicellulose using 2-sec-butylphenol (SBP) solvent

“…Typical processing strategies use different options of pretreatment, including dilute acid [8,9], hot water [10], ionic liquid [11][12][13], lime [14] and ammonia fiber expansion [15,16], to fractionate biomass into its components. After the pretreatment, the hemicellulose and cellulose fractions can be converted to various biofuels typically through three major routes: biochemical [17][18][19][20][21], thermochemical [17,[22][23][24][25][26][27][28][29][30], and catalytic [2,21,31,32], whereas lignin is used typically for heat and power generation through combustion [33]. The catalytic biofuel production from lignocellulosic biomass has lately attracted considerable attention compared to the other methods.…”

Recent trends on techno-economic assessment (TEA) of sugarcane biorefineries

“…Furthermore, conversion of EtOH into butanol has also been analysed by Dias et al (2014), which showed that butanol sold as chemical has a limited market and as fuel presents economic constraints. Pereira et al (2015) assessed two competing technological routes for the production of n-butanol (fermentative and catalytic route) as facilities annexed to a 1G-2G sugarcane biorefinery. Based on their study, ABE process despite its drawbacks performed better than the catalysis of ethanol to n-butanol and co-products (Pereira et al, 2015).…”
