IEA Bioenergy Task 39 releases new report on feedstock-to-biofuels

By -

Type of post: NEWS IN BRIEF.

IEA Bioenergy Task 39 (transport biofuels) commissioned India to lead a study on “Feedstock-to-biofuels”, especially a biomass supply chain assessment for the production of 2nd Generation (2G) ethanol, to help understand the developments in India and other groups/member countries. The study mainly focussed on biomass availability, prevalent biomass supply chain approaches, and different process schemes, including the type of pretreatment technologies used by 2G ethanol technology developers. Furthermore, the study included life cycle analysis and environmental impact assessment to identify the GHG emissions and energy consumption hotspots during the lignocellulosic bioethanol production process.

Publication date: 16/11/2015 Last update: 20/02/2016 Description 1,2 Levulinic acid (also known as 4-oxopentanoic acid or γ-ketovaleric acid) is an organic compound with chemical formula C 5 H 8 O 3 . It is a white crystalline solid soluble in water and polar organic solvents. It contains ketone and a carboxylic group whose presence results in interesting reactivity patterns. It is one of the more recognized Biobased Chemical Building Blocks , a starting material for a wide number of compounds (see Applications below). In fact, it was recognized by the US DoE as one of the top biobased platform chemicals of the future and it can successfully address many performance-related issues attributed to petroleum-based chemicals and materials. Process technologies 1,3,4,5 The controlled degradation of C6-sugars by acids is the most widely used approach to prepare levulinic acid from lignocellulosic biomass. Other methods have also been studied, for instance, the hydroly...

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

VTT releases its last results in bioplastic development - FDCA and muconic acid

For many experts, 2,5-Furandicarboxylic acid (FDCA) is called upon to revolutionise the biobased plastics industry in the near future. The main production material of drinking bottles is still oil-based PET using purified terephthalic acid (PTA) and ethylene glycol (EG). However, FDCA can replace PTA to obtain PEF, a new high-performance biopolymer. Recently, the Blog devoted a whole post to FDCA (see FDCA biorefineries ). Such post shows a non-exhaustive list of the most important processes developed or under research by companies and research institutes. VTT Technical Research Centre of Finland Ltd is working on one of them and it has just unveiled interesting information about it. Last week, in the webinar “ Green plastics without the bio-premium: FDCA and muconic acid transforming the industry ”, this Finish centre introduced its work on the aforementioned furan derivative and on the muconic acid, another versatile chemical with potential to change the polymer industry. The...

Fecha de publicación: 16/11/2015 Última actualización: 20/02/2016 Descripción 1,2 El ácido levulínico (también conocido como ácido 4-oxopentanoico o ácido γ-cetovalérico) es un compuesto orgánico con fórmula química C 5 H 8 O 3 . Es un sólido cristalino soluble en agua y en disolventes orgánicos polares. Contiene un grupo cetona y un grupo carboxilo cuya presencia posibilita patrones reactivos interesantes. Es uno de los “ Biobased Chemical Building Blocks ” más reconocidos, precursor de un amplio número de compuestos (véase el apartado Aplicaciones más abajo). De hecho, fue reconocido por el DoE como una de las principales moléculas plataforma del futuro y puede cubrir de manera eficaz muchas de las atribuciones de productos químicos y materiales procedentes del petróleo. Tecnologías de proceso 1,3,4,5 La degradación controlada de azúcares C6 mediante ácidos es el proceso más usado para preparar ácido levulínico a partir de biomasa lignocelulósica. Se han estu...

Figure 1. Goldilocks oil (taken from Vertoro website) This biorefinery will convert industrial wood residues like sawdust into some 50,000 tons of cellulosic ethanol, alongside roughly 125,000 tons of lignin-based Goldilocks crude oil. The crude has multiple applications including its use as a gasifier- and cracker feedstock as well as a marine fuel. GEM (Goldilocks Enriched Methanol) offers a lower average price per calorie and improves important combustio...
