Small scale Ethanol production with Stirred Catalytic Basket Reactor-SCBR, a new approach
Ethanol in general
Ethanol, also known as ethyl alcohol is a flammable and colorless chemical compound. In common language it is also known simply as alcohol. Its molecular formula is variously represented as C2H5OH or EtOH.
How ethanol is used?
Ethanol can be used as blends with normal gasoline. Typical mixture rates are as following:
* E5 – contains 5% ethanol, 95% gasoline
* E10 – contains 10% ethanol, 90% gasoline
* E85 – contains 85% ethanol, 15% gasoline (sold e.g. in Sweden and Germany)
E5 and E10 are compatible with most of modern cars and should not cause any issues when used. E85 requires so called flexifuel cars to be used.
Using ethanol as fuel is beneficial because it decreases the fuel's cost, increases the fuel's octane rating, and decreases gasoline's harmful emissions.
Ethanol is a renewable fuel
Ethanol production from biowaste, using various types of biodegradable waste helps reducing CO2 emissions dramatically.
Introduction to Development of a New Technology for the Production of Fuel Ethanol at High Rates with a Stirred Catalytic Basket Reactor with Immobilized Cells. Background to the challenge.
It seems that the research and technology development in Basket Reactor-SCBR is now starting to pick up speed and after studying a bit about different players in technology development globally and Ethanol projects underway in Scandinavia, Source Biodriv2022, I can see that there is a potential to produce scalable finished systems including certification to different target groups around the world.
Below is a short summary from our partner's research.
The results reported in this work sustain the belief that the production of ethanol with a SCBR system is feasible. Nonetheless, more work is needed with larger scale equipment in order to evaluate the influence of the other factors that influence the long term performance of the system.
In the last 20 years, the bio-production of ethanol has been subject of much research. Special consideration has been given to the development of ethanol-resistant strains of microorganisms, and to the development- through genetic engineering - of new strains able to ferment both glucose and xylose. These sugars are obtained from the acid hydrolysis of inexpensive biomass, such as agricultural residues, hemicellulose, wood and grasses. On the other hand, much less interest has been given to the design of new types of fermenters with increased volumetric productivities. Moreover, the concrete applications of these developments to the biochemical processes industries are scarce.
For many reasons, of a technological and cost-effective nature, the manufacturer of biochemicals needs a reactor able to meet a number of different running conditions, such as: varying viscosity, varying aeration rates, varying intensity of agitation and changing broth volume. All of these can be achieved in stirred tank type fermenters, as our reactor, but not so easily in other kinds of reactors.
Immobilized cell technology, represents for the biochemical process industry a radical advance, similar to the introduction of heterogeneous catalysis in the petrochemical and heavy chemical industries. However, research on the production of ethanol with immobilized cells has been limited to the classical fixed and fluidized beds. In fact, these systems, when applied to immobilized cell technology show a number of limitations2. Therefore, in order to make full use of the advantages of immobilized cell technology as applied to ethanol production; we need new reactors and new approaches. The impact that immobilized cell technology could have in the fuel ethanol industry is quite stimulating. For example, Blanco and Herryman10 have compared the economics of the production of ethanol with three different technologies and they conclude that cell immobilization could be up to ten times more productive and cost-effective than conventional, free cell systems.
We have extensive documentation about the research as well as various process models and access to the researcher as if you are interested in a collaboration you will receive.
We are now looking for partners and investors for the next generation Ethanol and Biogas production according to the latest research findings regarding Stirred Catalytic Basket Reactor-SCBR.
We can now offer a production process that provides a production of ethanol with very interesting results: a fermentation time of only 4 hours is an absolute record.
We want to get in touch with you to present the project and what we together can get out of it.
