Microvi's Biogas-To-Liquid technology has been awarded a grant from the US DOE

By -


Biogas is a product of anaerobic digestion of waste organic sources such as animal manure or food wastes. Its primary components are methane and carbon dioxide (tipical composition: 50–75% CH4, 25–50% CO2, 0–10% N2, 0–5% O2, 1000-2000 ppm H2S), potent greenhouse gases. Currently, much of the world’s biogas is used in direct combustion systems to produce electricity. Alternative choices are the use in stationary or mobile internal combustion engines and its injection into a natural gas pipeline previous upgrading.

However, biogas has also the potential to be the starting point for liquid biofuels and renewable chemicals. It can expand the range of products from biorefineries and waste treatment facilities. For example, biogas upgraded to biomethane can be converted to synthetic gas to produce fuels and chemicals via Fischer-Tropsch synthesis.

And there are new processes under development. A groundbreaking biocatalytic technology that converts methane and carbon dioxide from biogas into valuable liquid chemicals, has been awarded a grant from the US Department of Energy (see press release). This new technology is based in Microvi’s MicroNiche Engineering Platform Technology™ and has great promise to avoid the pitfalls of conventional Biogas-To-Liquid processes. Microvi is an industrial biotechnology company based in the San Francisco Bay Area that develops next-generation bioconversion technologies in the water, wastewater and chemical industries. MicroNiche Engineering, the company’s core discipline, is a synthetic biology approach that achieves remarkably reproducible kinetics for almost any biocatalytic process.

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
