Versión en Español Type of post: NEWS.  Last month, ten private- and public-sector partners ( Alco Bio Fuel , ArcelorMittal , ENGIE , Fluxys , Mitsubishi Power , North Sea Port , Oiltanking , PMV , POM Oost-Vlaanderen , Proman ) launched the North-C-Methanol project. Together they will reduce annually the CO2 emissions by 140,000 tons and generate 44,000 tons of green methanol, which can be used as feedstock for the chemical industry as well as fuel for ships and trains.  Press release: “ Multi-million-euro project transforms CO2 into green raw material in North Sea Port ”, 21/10/2020.  Figure 1. North-C-Methanol project concept (taken from the project website)   North-C-Methanol is the first project which is part of the North-CCU-Hub programme and right now represents an investment of 140 M€. It entails the construction of two large-scale demo plants and supporting infrastructure on the Rodenhuize peninsula in North Sea Port:  (1) A 65-MW electrolyser th...

Biobutanol biorefineries

Publication date: 08/02/2016 Last update: 18/12/2017 General description 1,2,3,4,5,6,7 Butanol is a four-carbon alcohol with chemical formula C 4 H 10 O. There are four possible isomers for this molecule: n-butanol, isobutanol, tert-butanol and sec-butanol. Their different structures have a straight impact on their physical and chemical properties. Figure 1. Isomers of butanol Biobutanol is commonly used to refer to the butanol produced from biomass. n-Butanol is the major natural product formed in ABE fermentation. Isobutanol can be produced in alcoholic fermentation. sec-Butanol cannot be directly obtained by fermentation although it can be generated via 2,3-butanediol from fermentative processes. tert-Butanol is not produced by any known biological route. For the purposes of this post, biobutanol will stand for n-butanol, isobutanol or both of them, depending on the case. Butanol formation through anaerobic bacteria fermentation was already observed by ...

DRT (Dérivés Résiniques et Terpéniques) announced on 14 th September, the commissioning of its new tall-oil biorefinery on its site of Vielle-Saint-Girons (France). DRT is headquartered in Southwestern France (Landes region) and it has 4 production sites in France, 1 in China and 3 in India. The company is specialized in the valorization of rosin and turpentine extracted from pine resin and, to meet the growing demand of the international markets, has decided to increase its production capacities thanks to a new tall-oil fractionation technology. Figure 1. Aerial shot of the DRT site in Vielle-Saint-Girons (extracted from DRT webpage) Tall-oil is a liquid obtained as a by-product of the Kraft process of wood pulp manufacture when pulping mainly coniferous trees. Normally, crude tall-oil contains resin acids, fatty acids and unsaponifiable substances (sterols and other alkyl hydrocarbon derivatives). The crude tall oil does not have a great commercial value, however, whe...

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...

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: Etanol celulósico - Lo básico: Concepto y materias primas - Lo básico: Ruta de conversión – Bioquímica - Lo básico: Ruta de conversión –Termoquímica - Cellulosic ethanol biorefineries at commercial scale Entradas: ETANOL CELULÓSICO 1. Introducción El proceso de conversión bioquímica ha sido el que ha generado mayor atención debido a sus similitudes con el proceso utilizado para producir etanol a partir de maíz. Como se puso de manifiesto en la primera entrada de esta serie, el proceso de producción de etanol a partir de materias primas celulósicas requiere descomponer la materia prima en azúcares fermentables a través de tecnologías innovadoras en forma de pretratamiento e hidrólisis. Los pasos restantes son similares a los utilizados en las plantas de etanol convencionales. 2. Pretratamiento El pretratamiento es el primer paso en todos los diferentes procesos disponibles para la ruta de conversi...
