Ethanol production from lignocellulosic materials is often conceived considering independent, stand-alone plants; in the Brazilian scenario, where part of potential feedstock (sugarcane bagasse) for second generation ethanol already available at conventional first plants, an integrated and process seems to be most obvious option. In this study surplus sugarcane bagasse trash compared with generation; simulations were developed represent different technological scenarios, which provided data...
Ethanol production from lignocellulosic feedstocks (also known as 2nd generation or 2G ethanol process) presents a great potential for reducing both costs and climate change impacts since agricultural residues dedicated energy crops are used feedstock. This study aimed at the quantification of economic environmental considering current future scenarios sugarcane biorefineries taking into account not only improvements industrial process but also biomass systems. Technology assumptions setup...
The techno-economics of greenfield projects a first-generation sugarcane biorefinery aimed to produce ethanol, sugar, power, and n-butanol was conducted taking into account different butanol fermentation technologies (regular microorganism mutant strain with improved yield) market scenarios (chemicals automotive fuel). complete the batch acetone-butanol-ethanol (ABE) process simulated using Aspen Plus®. designed 2 million tonne per year utilize 25%, 50%, 25% available juice butanol,...
This paper presents the techno-economics of greenfield projects an integrated first and second-generation sugarcane biorefinery in which pentose sugars obtained from biomass are used either for biogas (consumed internally power boiler) or n-butanol production via ABE batch fermentation process. The complete was simulated using Aspen Plus®. Although pentoses stream available gives room a relatively small biobutanol plant (7.1-12 thousand tonnes per year), introduction butanol acetone to...
Abstract Bio‐based succinic acid is a potential building block for the production of renewable chemicals and polymers. The use hemicellulosic hydrolyzate from sugarcane bagasse allows without competing with food chains increasing biomass ‐aggregated value. This work assesses economic impacts integrating ‐succinic on an optimized biorefinery first‐generation ethanol electricity. Process simulation was performed to obtain mass energy balances entire process, pre‐treatment pentose fermentation...
Approximately 7% of Brazilian electricity is generated from sugarcane biomass. Although this scenario relatively optimistic when compared to the fossil-based energy matrix other nations, there a clear opportunity expanding bioelectricity production in country even more. Recent changes environmental legislation are progressively prohibiting burning before harvesting Center-South region. Consequently, straw (i.e., tops, dry and green leaves) has become available most fields. When considering...
Sugarcane straw has become available in large quantities the field due to transition from manual mechanical harvesting. Straw can be used as fuel for cogeneration systems of sugarcane mills increase surplus electricity commercialization. However, exploitation potential is still limited some challenges related its agricultural recovery and industrial processing. The retrofit (additional installation) existing process an alternative reduce investment allow a gradual utilization this biomass....
The Virtual Sugarcane Biorefinery (VSB) is a simulation and evaluation tool designed to assess the development of new technologies innovations in production processing biomass. VSB integrates computer platforms with economic, social, environmental tools sustainability impacts different sugarcane biorefinery alternatives. It considers all phases process, from conversion products use disposal. can evaluate stage perform comparative assessments alternatives, which make it great potential...
Furfural is a base chemical with wide range of applications and great opportunity for market growth in the near term. Derived from biomass, its production may be incorporated to Brazilian industry using sugarcane bagasse as feedstock. In this context, integration furfural plant first generation bioethanol facility, within biorefinery concept, was simulated considering different scenarios compared an autonomous distillery. The economic analysis showed that revenues commercialization increase...
Technoeconomic and life-cycle analyses are presented for catalytic conversion of ethanol to fungible hydrocarbon fuel blendstocks, informed by advances in catalyst process development. Whereas prior work toward this end focused on 3-step processes featuring dehydration, oligomerization, hydrogenation, the consolidated alcohol dehydration oligomerization (CADO) approach described here results 1-step wet vapor (40 wt% water) hydrocarbons water over a metal-modified zeolite catalyst. A...
