Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

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 propieda...

Versión en Español Section: ADVANCED BIOFUELS Series: HVO - Hydrotreating (HVO) – Concepts, feedstocks and specifications - Hydrotreating (HVO) – Advantages over FAME and properties - Hydrotreated Vegetable Oils (HVO) Biorefineries – The rise of renewable diesel - Posts: HVO                The acronym HVO stands for “ Hydrotreated Vegetable Oils ” or ” Hydrogenated Vegetable Oils ”. Key of the process: Treatment with hydrogen. In the HVO production process, hydrogen is used to remove the oxygen from the triglycerides producing a mix of linear paraffins, CO 2 and water. Then, the product of the first stage is isomerized, always in presence of hydrogen, in order to branch the linear chains for improving the cold flow properties of the final products. Thus, HVO are mixtures of paraffinic hydrocarbons, free of sulphur and aromatics and with a very high cetane number. The hydrocarbons...

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). Shandong Sanju Bio...

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...
