Bioethanol Liquefaction Production Service

In addition to providing technical support services for fermentation technology of bioethanol production, Lifeasible also provides technical support services for liquefaction technology of bioethanol production.

Liquefaction is a thermochemical technology that can utilize a variety of biomass for bioethanol production. The raw materials for this technology can be wood waste, crop residues, energy crops, etc. Liquefaction technology has one advantage over common fermentation production methods, which makes more use of biomass materials. For example, lignin cannot be degraded by fermentation technology, while liquefaction technology can utilize lignin of biomass.

Bioethanol liquefaction production mainly involves two steps. First, biomass materials need to be gasified to produce syngas which can be liquefied to produce bioethanol. The second step has two ways, one is chemical reaction through the catalyst, and the other is fermentation of syngas to produce bioethanol.

In the gasification process, the biomass material is first mixed with air, oxygen and/or steam, then the mixture reacts in a high temperature environment to form a gas mixture, which includes different proportions of CO, H₂, CO₂, CH₄, and N₂. The syngas is filtered prior to entering the next step to remove unwanted components. The proportion of the components for different gases in the syngas is related to gasifier type, biomass type and reaction conditions. Lifeasible has extensive experience in liquefaction technology. We can make meaningful recommendations for the selection of gasifiers and the setting of reaction parameters in the gasification process to help you increase the final yield of bioethanol.

Liquefaction of syngas in bioethanol production involves two methods. The first method utilizes the Fischer–Tropsch (FT) reaction, which is carried out under high temperature and high pressure, and it has the advantages of high reaction rate and high conversion rate. In this process, water and methanol need to be added to increase the production of bioethanol. In addition, rhodium (Rh), cobalt and molybdenum are selected as catalysts to promote the reaction for syngas. The second method is to produce bioethanol by microbial fermentation of syngas, which has the advantages of mild conditions and low requirements on the proportion of gas in the syngas. Syngas is filtered and cooled to room temperature, and then subjected to microbial fermentation in an ethanol conversion chamber to convert the syngas to ethanol and acetic acid. In order to obtain the final products, the liquefied products need to be distilled to separate the ethanol from other products. The liquefaction process of bioethanol production is influenced by many factors, including bioreactor type, catalysts, and reaction conditions. Experience of Lifeasible in bioethanol liquefaction production can help you make the best choice when solving these problems, and design a better production process scheme.

Lifeasible not only provides technical consulting services related to bioethanol liquefaction production, but also provides services that design processes based on raw material types and production conditions, as well as services that optimize production processes to increase conversion rates and reduce production cost.
