100,000-ton bioethanol project established in Inner Mongolia
Thread Content
A project with a total investment of 1.35 billion yuan, capable of producing 100,000 tons of fuel ethanol from sweet sorghum stalks per year, was established on April 20 in Wuyuan County, Inner Mongolia Autonomous Region. According to the **Office of Wuyuan County, the project covers a total area of 1,500 mu and is being constructed in two phases. The first phase is scheduled to require an investment of 418 million yuan; it involves the implementation of an advanced technology integration project for producing 30,000 tons per year of fuel ethanol from sweet sorghum stalks. Completion and commissioning of this phase are planned for August 15 this year. Once completed and brought into operation, this project will be able to make use of 1.5 million mu of marginal land, provide employment for 30,000 surplus rural workers, and achieve a reduction of 300,000 tons in carbon dioxide emissions.
Substantial progress has finally been made in using sweet sorghum to produce fuel ethanol: after the sorghum is juiced, the sugar solution is fermented directly, while the bagasse is used for paper production and as feed, thereby helping to address the food crisis! This step must be taken as part of the energy strategy; Brazil’s technology is quite advanced! There isn’t much large-scale production in the country at the moment!
Why isn’t slag used to produce fiber ethanol?
The cost is too high if slag is used to produce fiber ethanol! Producing alcohol from sugar syrups is not the same process; cellulase is needed to break down small molecules of starch and dextrin, which are then converted into glucose through saccharification, before fermentation takes place! Or carry out acid hydrolysis on the fibers! The process is complex and costly; it’s better to use it directly as feed or for papermaking!
Has construction on this project started? Which manufacturer’s equipment? Do we need more people? I hope someone who knows can provide some relevant information.
4# henan2006 Cellulase can break down the residue into glucose, which can then be fermented; adding two or three more devices should suffice.
Although Novozymes and COFCO have projects related to cellulose ethanol, cellulase has not yet reached a level suitable for industrial use.
Finally, the construction of the factory is underway; I wonder what good solutions exist for storing raw materials.
Reply 1# huaandhua: The alcohol production process using sweet sorghum was perfected several years ago. The problem is that the source material is available over such a large area; it’s unclear how the economic and social impact assessments were approved. What I know is that this process actually involves two types of raw materials, corn and sweet sorghum – with a seasonal replacement of these raw materials. It is difficult for factories of such a large scale that use sweet sorghum as raw material to be economically viable.
I just want to take a look; I’m not really inclined to give my opinion. There are no particularly difficult issues in the industrial sector, but ensuring a supply of raw materials might be an obstacle that cannot be overcome! It’s not just a rumor; the construction work has already begun, and the equipment has been ordered.
