Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 25/05/2021. Last update: 25/05/2021. Description - C6 aliphatic dicarboxylic acid. - White crystalline powder. - Other names: hexanedioic acid; 1,4-butanedicarbocylic acid. Applications - Monomer for the production of nylon 6,6. - Monomer for the production of polyurethane. - Manufacture of plasticizers and lubricants. - Gelling and acidulant agent (food grade). Conventional petrochemical route - Oxidation of cyclohexane to produce KA oil (cyclohexanone and cyclohexanol) / Nitric acid oxidation of KA oil. During the final reaction, the highly potent GHG nitrous oxide (N2O, 300 times more potent than carbon dioxide) is formed. It has been estimated that replacing the current petrochemical-based process with one employing renewable precursors will reduce greenhouse gas emissions by up to 95%, depending on the process used (1). Main biobased routes - [Muconic acid via] Fermentatio

Publication date: 16/10/2015. Last update: 20/12/2016. Introduction The blog will open soon a new section focused on summarizing the information available about the commercial and pilot plants of the most promising Biobased Chemical Building Blocks (BCBB). The section will contain links to monographic posts updated in a regular basis. I have chosen bio-succinic acid to start the series because some companies have achieved important milestones related to its large-scale commercialization. Clearly, it is one of the DoE´s top 12 BCBB that it is fulfilling the previous generated expectations. Description 1,2,3 Succinic acid (butanedioic acid), is a diprotic, dicarboxylic acid with chemical formula C 4 H 6 O 4 . It is a water-soluble, colorless crystal with an acid taste. The name derives from Latin “succinum”, meaning amber, from which the acid was originally obtained by pulverising and distilling it using a sand bath. It is produced naturally as a product of cellul

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.

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: HVO - Hidrotratamiento (HVO) – Conceptos, materias primas y especificaciones - Hidrotratamiento(HVO) – Ventajas sobre el biodiesel convencional y propiedades - Biorrefinerías de Aceites Vegetales Hidrotatados (HVO) – El auge del diésel renovable - Entradas: HVO                El acrónimo HVO significa en inglés “ Hydrotreated Vegetable Oils ” (“Aceites Vegetales Hidrotratados”) o ” Hydrogenated Vegetable Oils ” (“Aceites Vegetales Hidrogenados”). 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

Versión en Español Type of post: NEWS. According to S&P Global Platts, last month, State-owned energy company Beijing Sanju Environmental Protection & New Materials launched a 400 ktons/year capacity HVO plant in Rizhao (Shandong, China) province. The biorefinery utilizes used cooking oil (UCO) and palm oil mill effluent (POME) as feedstocks. News (S&P Global Platts): “ China reinforces position in HVO market with launch of new 400,000 mt/year plant ”, 24/03/2021. Hydrotreating (HVO) – Concepts, feedstocks and specifications . HVO posts. Figure 1. Beijing Sanju, current and planned HVO plants (source: S&P Global Platts Analytics) The new HVO plant (Shandong Sanju Bioenergy) was the result of a cooperation agreement (07/04/2020) between Beijing Sanju (primary owner, investor and tech provider), Hainan Qilu Development (investor and subsidiary of Qilu Transportation Development Group) and the Juxian County Government (minority owner, fixed assets).
