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.

Fecha de publicación: 26/04/2017 Última actualización:  26/04/2017 Introducción [1,2,3] Una instalación de primera generación (1G) produce bioetanol mediante la fermentación de azúcares procedentes de la caña de azúcar, la remolacha azucarera o semillas de cereales, mientras que una instalación de segunda generación (2G) emplea los azúcares que se pueden encontrar en la biomasa lignocelulósica (residuos agrícolas, cultivos lignocelulósicos…). Se dice que la hibridación de las instalaciones 1G con tecnología 2G es el futuro para los biocombustibles 2G en aquellos países que ya han desarrollado una infraestructura fuerte para producir bioetanol. La hibridación permite producir etanol más competitivo en coste usando residuos agrícolas que previamente no tenían valor e integrando toda la cadena de valor. En este contexto, hay un modo especial de hibridación que aprovecha los azúcares celulósicos escondidos en la fibra del grano de maíz. Conocida comúnmente como Generac...

Versión en Español Type of post: NEWS. Mura has announced that construction has started on the world’s first commercial-scale plant to use its HydroPRS process in Teesside (UK). HydroPRS (Hydrothermal Plastic Recycling Solution) is an advanced technology for plastic recycling. Press release: “ Mura Announce Teesside Project Commences Build & New Partnerships ”, 25/03/2021. Figure 1. Simplified diagram of the Mura process The Teesside plant is expected to be operational in 2022. It will be able to process 80,000 tons of plastic waste per year. On completion, it will have the capacity to avoid up to 120,000 tons of CO2 emissions per year, compared to incineration of the same plastic waste. The project will form the blueprint for a rapid global rollout that will see one million tons of capacity in development worldwide by 2025. Sites are planned in Germany, the US and Asia. Mura’s proprietary HydroPRS process, utilising Cat-HTR technology (developed and owned by Licella Hol...

Publication date: 14/12/2015 Last update: 24/05/2017 Description 1,2,3,4 D-Glucaric acid, also called saccharic acid, is a chemical compound with formula C 6 H 10 O 8 and member of a large family of molecules known as oxidized sugars. It is a naturally occurring aldaric acid, typically found in small amounts in a variety of fruits and vegetables. It is a highly functionalized compound with four chiral carbons and a plethora of reaction pathways. Its commercial potential was unveiled in the report “Top Value Added Chemicals from Biomass” from the Department of Energy of USA which described its use as a building block for a number of polymers, including new nylons and hyperbranched polyesters. Process technologies 1,3,4,5,6,7,8 The synthetic preparation of D-glucaric acid dates back to a report of Sohst and Tollens (1888) who carried out the nitric acid oxidation of D-glucose to D-glucaric acid. Current methods for its production are based on this process and in...

Introduction The biochemical conversion process has attracted the most attention because of its similarities to the process used to produce ethanol from corn grain. As it was highlighted in the first post of this series, the production process for ethanol made from cellulosic feedstocks requires breaking down the feedstock into fermentable sugars through innovative technologies in the form of pretreatment and hydrolysis. The remaining steps are similar to those used in conventional ethanol plants. 2. Pretreatment The pretreatment is the first step in all of the different processes available for the biochemical conversion pathway but the definition of this unit operatio...
