Glucaric acid biorefineries

By

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...

Fecha de publicación: 14/12/2015 Última actualización: 24/05/2017 Descripción 1,2,3,4 Él ácido d-glucárico, también llamado ácido sacárico, es un compuesto químico con fórmula C 6 H 10 O 8 y miembro de una familia extensa de moléculas conocidas como azúcares ácidos. Se trata de un ácido aldárico que se produce de manera natural que se encuentra típicamente en una gran variedad de frutas y vegetales. Es un compuesto altamente funcionalizado con cuatro carbonos quirales y una gran gama de rutas de reacción. Su potencial comercial fue puesto de relevancia en el informe “ Top Value Added Chemicals from Biomass ” del DoE de USA que describe su uso como precursor de polímeros, incluyendo nuevas poliamidas y poliésteres altamente ramificados. Tecnologías de proceso 1,3,4,5,6,7,8 La primera mención de la preparación sintética del ácido D-glucárico está fechada en 1888. Se trata de un informe de Sohst y Tollens, los cuales llevaron a cabo la oxidación nítrica de la D-g...

Biorefinery true colors

By
Image
Recently, I was searching for information to document a post when I ran into an interesting classification of biorefineries. It was based on colors that were assigned to different feedstocks. Some of the designations were familiar to me, others less so. I thought that it was a very intuitive way to learn the basics of raw materials in biorefining systems. This is why I have prepared this post about the “biorefinery true colors”. Before starting to write, I looked for other references of this classification and I only could find some presentations of the same author: Lene Lange (Professor at Aalborg University and CSO of Barentzymes AS). According to her, one can distinguish between five types of biorefineries taking into account the feedstock 1,2,3 : Blue Biorefinery based on marine biomass (fish waste and discard, algae); Brown Biorefinery based on sludge and household waste; Green Biorefinery based on fresh green leaves and grass; White Biorefinery (or Grey Biorefinery) based...

Versión en Español Type of post: NEWS. Södra has built a plant for commercial biomethanol production at its pulp mill in Mönsterås (Sweden). Over the next few days, a first pilot delivery will go to Emmelev A/S , a customer that will be using biomethanol in its biodiesel production. Press release: “ Södra first in the world with fossil-free biomethanol ”, 20/2/2020. Related posts: “ Andritz to supply a biomethanol plant for a project of Södra in Mönsterås ”, 21/5/2018. Figure 1. Södra biomethanol plant at Mönsterås mill Södra decided to invest in a biomethanol production facility in 2017 to produce 5,000 tons per year of this chemical. The plant has been supplied by Andritz. In the chemical wood pulping process of Södra’s mill, methanol is formed as a by-product that contains many impurities. This raw methanol is purified to a merchantable biomethanol which is chemically identical to fossil-based methanol. Emmelev is a Danish family-owned agricultural company...
