Etanol de la fibra del grano de maíz – Las tecnologías 1,5G a estudio

By

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...

Versión en Español Type of post: NEWS IN BRIEF. Sustainable Technology Corporation (STC), a subsidiary of Petron Scientech Inc. , has completed the acquisition of DuPont’s 2G ethanol technology assets, capable of commercially producing ethanol from cellulosic biomass. Ethanol Producer Magazine: “ Sustainable Technology acquires DuPont’s G2 ethanol technology ”, 18/10/2019. Figure 1. Logo of STC The acquired assets include all associated intellectual property and patents including that for process design and the zymomonas ethanologens . The acquisition of this technology by STC allows Petron Scientech to expand the family of renewable fuels and chemicals technologies that it licenses and provides (biofuels, olefins from alcohols, ethylene oxide, ethylene glycol, PE, EDC and SBR). STC plans to license the technology globally, including in biorefineries under development by BioChem USA LLC (see “ BioChem USA to set up a biorefinery in the Indian state of Gujarat ”, 6/...

Versión en Español Section: ADVANCED BIOFUELS Series: Cellulosic ethanol - The basics: Concept and feedstocks - The basics: Conversion pathway – Biochemical - The basics: Conversion pathway –Thermochemical - Cellulosic ethanol biorefineries at commercial scale Posts: CELLULOSIC ETHANOL 1. 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...

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...
