trends in biotechnological production of Fuel Ethanol from different feedstocks
Bioresource Technology, 2008Co-Authors: Oscar Sanchez, Carlos A. CardonaAbstract:Present work deals with the biotechnological production of Fuel Ethanol from different raw materials. The different technologies for producing Fuel Ethanol from sucrose-containing feedstocks (mainly sugar cane), starchy materials and lignocellulosic biomass are described along with the major research trends for improving them. The complexity of the biomass processing is recognized through the analysis of the different stages involved in the conversion of lignocellulosic complex into fermentable sugars. The features of fermentation processes for the three groups of studied feedstocks are discussed. Comparative indexes for the three major types of feedstocks for Fuel Ethanol production are presented. Finally, some concluding considerations on current research and future tendencies in the production of Fuel Ethanol regarding the pretreatment and biological conversion of the feedstocks are presented.

Fuel Ethanol production process design trends and integration opportunities
Bioresource Technology, 2007Co-Authors: Carlos A. Cardona, Oscar SanchezAbstract:Abstract Current Fuel Ethanol research and development deals with process engineering trends for improving biotechnological production of Ethanol. In this work, the key role that process design plays during the development of cost-effective technologies is recognized through the analysis of major trends in process synthesis, modeling, simulation and optimization related to Ethanol production. Main directions in techno-economical evaluation of Fuel Ethanol processes are described as well as some prospecting configurations. The most promising alternatives for compensating Ethanol production costs by the generation of valuable co-products are analyzed. Opportunities for integration of Fuel Ethanol production processes and their implications are underlined. Main ways of process intensification through reaction–reaction, reaction–separation and separation–separation processes are analyzed in the case of bioEthanol production. Some examples of energy integration during Ethanol production are also highlighted. Finally, some concluding considerations on current and future research tendencies in Fuel Ethanol production regarding process design and integration are presented.

Technical,economic and environmental analysis of Fuel Ethanol production from sugarcane in China
Renewable Energy, 2006Co-Authors: Wang Ge-huaAbstract:Based on national strategies of oil security,Chinese government started "Denatured Fuel Ethanol" program and "Ethanol gasoline for motor vehicles" program in 2001,which is the background of the development of sugarcane Fuel Ethanol production in China.The utmost development barrier of Fuel Ethanol is the high cost,thus large amount of subsidies are required from national government.With the successful experience of sugarcane Fuel Ethanol production in Brazil as reference,the article assesses technical,economic and environmental possibilities of the same industry in China and comes to the conclusions: China already has the technical ability to produce Fuel Ethanol from sugarcane and to control negative environmental impact;by comparison with current price of Fuel Ethanol and sugar,sugarcane Ethanol has certain advantages;the negative impact on environment stemmed from the production of Fuel Ethanol from sugarcane can be overcomed,meanwhile,Fuel Ethanol production from sugarcane will also promote the reduction the greenhouse gas emission.

Fuel Ethanol Trade: Current Barriers and Perspective
International Energy Journal, 2008Co-Authors: Arnaldo Walter, Frank Rosillo-calleAbstract:Fuel Ethanol consumption has grown rapidly in recent years but both production and consumption are still mostly concentrated in US and Brazil. Due to the size of their potential markets, the US and the European Union – EU – will have a crucial role on international biotrade, inducing or constraining Fuel Ethanol production in developing countries. However, both US and EU have trade regimes based on tariffs that offset the comparative advantages of some producer countries. This paper analyses current trade regimes on Fuel Ethanol and the perspectives in short- to mid-term. It is shown that Fuel Ethanol trade can significantly reduce the supply cost in the main markets (US and EU) and also induce the development of the Ethanol industry in emerging producing countries. Without imports it seems very difficult to reach the targets recently set in US and EU; besides physical constraints for local production based on conventional feedstocks, the supply cost would be very high if large-scale production was to take place based on corn and wheat, for instance. Some short- to mid-term term tendencies in the Fuel Ethanol market are identified and analysed, including: (i) how US and EU tend to preserve their traditional domestic production until second generation of bioFuels becomes commercially available, (ii) the impact of quotas in US and EU on Fuel Ethanol imports, to induce production in other countries, (iii) requirements for certification of bioFuels production – primarily in the EU – to insure the adoption of the main sustainability practices .

Perspectives on Fuel Ethanol consumption and trade
Biomass and Bioenergy, 2008Co-Authors: Arnaldo Walter, Frank Rosillo-calle, Paulo Dolzan, Erik Piacente, Kamyla Borges Da CunhaAbstract:Abstract Since the year 2000 or so there has been a rapid growth on Fuel Ethanol production and consumption, particularly in US and Brazil. Ethanol trade represented about 10% of world consumption in 2005, Brazil being the main exporter. The most important consumer markets—US and European Union (EU)—have trade regimes that constrained the comparative advantages of the most efficient producers, such as Brazil. This paper evaluates the Fuel Ethanol market up to 2030 together with the potential for international biotrade. Based on forecasts of gasoline consumption and on targets and mandates of Fuel Ethanol use, it is estimated that demand could reach 272 Gl in 2030, displacing 10% of the estimated demand of gasoline (Scenario 1), or even 566 Gl in the same year, displacing about 20% of the gasoline demand (Scenario 2). The analysis considers Fuel Ethanol consumption and production in US, EU-25, Japan, China, Brazil and the rest of the world (ROW-BR). Without significant production of Ethanol from cellulosic materials in this period, displacing 10% of the gasoline demand in 2030, at reasonable cost, can only be accomplished by fostering Fuel Ethanol production in developing countries and enhancing Ethanol trade. If the US and EU-25 reach their full production potential (based on conventional routes), the minimum amount that could be traded in 2030 would be about 34 Gl. Displacing 20% of the gasoline demand by 2030 will require the combined development of second-generation technologies and large-scale international trade in Ethanol Fuel. Without second-generation technologies, Scenario 2 could become a reality only with large-scale production of Ethanol from sugarcane in developing countries, e.g., Brazil and ROW-BR could be able to export at least 14.5 Gl in 2010, 73.9 Gl in 2020 and 71.8 Gl in 2030.
