NextChem and LanzaTech partner to produce renewable ethanol

By -

Type of post: NEWS IN BRIEF.

NextChem has signed an agreement with LanzaTech for the license of its carbon recycling process. In this way, the Italian company will expand its circular economy and chemical recycling technology portfolio (CircularDistrict) with the production of renewable ethanol.
Press release: “Nextchem and LanzaTech Sign an agreement to promote circular ethanol production”, 17/7/2020.
Figure 1. Nextchem and LanzaTech join forces to produce renewable ethanol

The CircularDistrict model of NextChem, subsidiary of Maire Tecnimont that operates in the field of green chemistry, already had circular hydrogen and circular methanol production technologies (currently in the engineering phase). Now, it will be also possible to obtain ethanol, an important chemical for sustainable fuels and disinfectant production. NextChem will exclusively license this technology in Italy and, on a project basis, in some foreign markets.

The process is based on the chemical conversion of hydrogen and carbon contained in plasmix (non-recyclable waste from plastics separate collection) and RDF (Refuse Derived Fuel) to generate Circular Gas that can be used to produce various chemical products. With LanzaTech’s biological syngas fermentation technology, ethanol is produced by bacteria, transforming the Circular Gas at low temperature and low pressure, improving the overall sustainability profile of the process.

The technological integration of CircularDistrict model is among the most relevant innovations in the circular economy sector, as it allows the generation of products such as hydrogen, methanol, ethanol, from the currently non-recyclable waste, avoiding fossil sources and reducing climate-changing emissions.

Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems.

Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propiedades de flujo en frío de los productos finales. Por tanto, los HVO son

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

Publication date: 15/06/2017 Last update: 24/01/2018 Introduction 1,2,3,4,5 2,5-Furandicarboxylic acid (FDCA), also known as dehydromucic acid and pyromucic acid, is an organic compound that was first detected in human urine. In fact, a healthy human produces 3-5 mg/day. It is a very stable compound. Some of its physical properties, such as insolubility in most of common solvents and a very high melting point (it melts at 342 °C), seem to indicate intermolecular hydrogen bonding. FDCA has two carboxylic acid groups, which makes it a suitable monomer for polycondensation reactions with diols or diamines. It is one of the top 12 value-added biobased chemicals listed by the US DoE in 2004. The list was updated in 2010 and FDCA was included again, but this time in a group together with furfural and 5-hydroxymethylfurfural (5-HMF). Those three molecules are the main representatives of the furanics (furan derivatives) that has been referred to as “Sleeping Giants” beca
