Global Bioenergies demo plant in Leuna operates successfully its entire process

By -


The demonstration plant of Global Bioenergies, located in Leuna, has successfully operated its entire technical process: fermentation, purification and filling station (see press release). The facility is devoted to the production of isobutene from renewable raw materials. As is well known, this molecule is used as an intermediate in the manufacturing of a variety of products: fuels and fuels additives (it reacts with methanol and ethanol to generate MTBE and ETBE, respectively; its alkylation with butane produces isooctane), polymers (butyl rubber), paints, cosmetics and so on.

Project datasheet:
Location
Facility owned by the Fraunhofer CBP at the Leuna refinery platform.
The Fraunhofer team is in charge of operating the facility in the most effective way possible.
Feedstock
1G sugars: beets and cane, glucose syrup from cereals.
2G sugars: wheat straw, bagasse, wood chips…
Product and production capacity
100 ton/year of isobutene.
Investment
11 M€.

Timeline:
Mid-2015
Start of the construction.
End of 2016
Completion of the construction (see press release).
First months of 2017
Gradual start-up of the unit.
April 2017
The fermentation unit was the first section started-up.
Fermentation performances previously obtained on the pilot plant located at Pomacle-Bazancourt were replicated and even exceeded
(see press release).
August 2017
Site maintenance.
September 2017
Restarting of the plant.
Initial test involving the full technical process.
First bottle was filled.

The words of Marc Delcourt, CEO of Global Bioenergies, summarize well the next steps: “With this achieved, Global Bioenergies is now looking to the future. This means gradually approaching the process’ commercial performances, prior to building IBN-One, the first commercial plant project that we have with Cristal Union, the second largest French sugar producer. In a strongly improving macro-economic context (price of sugar sharply down; price of oil sharply up; energy transition now at the heart of global concerns, etc.), our ambition is to establish a large number of plant projects in various geographic areas.”

Alcohol-To-Fuel

By -

Type of post: OVERVIEW. Introduction Bioethanol produced from fermentation of sugar based crops is the major product of the biofuels industry [1]. But, ethanol is not a “drop-in” solution and requires substantial changes in refining or distribution infrastructure. The properties of this alcohol (an oxygenated single molecule) are largely different than those of gasoline, diesel and jet fuel blendstocks (mixtures of hydrocarbons), leading to problems in blends. Ethanol can cause corrosion problems in transport pipelines that were designed to work only with gasoline. In the specific case of the aviation fuel, there are stricter quality requirements than fuels used in road transport. Ethanol shows low compatibility as a blendstock for aviation fuel because of its high volatility and water absorption and low flash point and energy density. Butanol is not as incompatible as ethanol, however, it still poses unacceptable safety risks due to its low flash point and high volatilit...

A new addition to the list of references of small-scale biorefineries . Today I introduce a concept that is revitalizing the rural zones in Argentina: the MiniDest. Porta carries the distillery to the farm to integrate the production in the origin minimizing logistic and energy costs. The company Porta Hnos. SA , a company settled in Córdoba (Argentina), has a well-known industrial trajectory of more than 130 years in the production of liquor, alcohol and vinegar. They have invested years devoted to the development of engineering and technology for the processes of distillation and fermentation. In this sense, its staff have achieved important goals for the own company and third parties, in addition to the sign of collaboration agreements with major biotechnology companies in Argentina and all over world. The MiniDest concept The MiniDest are small, modular, automatic and remotely operated plants. These mini distilleries are installed in farms aimed to produce cor...

Publication date: 16/11/2015 Last update: 20/02/2016 Description 1,2 Levulinic acid (also known as 4-oxopentanoic acid or γ-ketovaleric acid) is an organic compound with chemical formula C 5 H 8 O 3 . It is a white crystalline solid soluble in water and polar organic solvents. It contains ketone and a carboxylic group whose presence results in interesting reactivity patterns. It is one of the more recognized Biobased Chemical Building Blocks , a starting material for a wide number of compounds (see Applications below). In fact, it was recognized by the US DoE as one of the top biobased platform chemicals of the future and it can successfully address many performance-related issues attributed to petroleum-based chemicals and materials. Process technologies 1,3,4,5 The controlled degradation of C6-sugars by acids is the most widely used approach to prepare levulinic acid from lignocellulosic biomass. Other methods have also been studied, for instance, the hydroly...
