Abstract: Biobutanol, a high-energy biofuel made from biomass, has better application prospects than bioethanol. With the dwindling of petroleum resources, biobutanol is one of the preferred alternatives to petroleum and other fossil energy sources. However, in addition to butanol, the biobutanol fermentation broth contains acetone, ethanol and most of the water. Poor separation effect and high separation cost have become one of the bottlenecks for the development of biobutanol. Therefore, the development of efficient and energy-saving separation technology is one of the keys to the industrialization of biobutanol. The traditional purification method has the fermentation broth first distilled in a prefractionator to remove the fermentation solids and some of the water, resulting in a concentrated organic solvent. The solvent is then separated by distillation to obtain ethanol, acetone and n-butanol. Aiming at the problem of difficult and energy-consuming separation of biobutanol fermentation broth, we introduce emerging separation techniques such as adsorption, gas extraction, pervaporation, and pertraction. Particular emphasis is placed on the salting-out process which improves the traditional distillation section of biobutanol production. Removing most of the water in the fermentation broth through the salting-out process can greatly reduce the energy consumption of subsequent distillation operations, providing a new efficient and energy-saving separation method. These salting agents are cheap and easy to obtain, easy to recover and recycle, and the inorganic salt used will not pollute the environment. Salting-out process is featured with mild conditions and simple operation, not only saving energy consumption, but also reducing CO2 emissions, and realizing energy saving and emission reduction.Abstract: Biobutanol, a high-energy biofuel made from biomass, has better application prospects than bioethanol.

Abstract: As global energy demand continues to grow, and environmental awareness increases, traditional fossil fuels are no longer able to meet humanity's aspirations for a better life and the pursuit of environmental protection. In response to the urgent needs of the people and in line with the trends of the times, the Chinese government has proposed the "dual carbon" targets for addressing pollution issues in China. Hydrogen energy, as a highly clean and new form of energy, is gradually becoming a key focus in research to address these dual carbon challenges. China, as one of the world's largest hydrogen gas producers, has also made significant progress in hydrogen research and applications. However, for hydrogen fuel to fully replace traditional fossil fuels, further research and development are required. Hydrogen gas storage and transportation also face many technical and practical difficulties and challenges. The development of hydrogen energy poses both challenges and opportunities for professionals in the storage and transportation industry. Hydrogen gas has been known to humanity for over a century, and the fundamental reason it has not been widely used as an energy source lies in the extreme difficulty of its storage and transportation. If the storage and transportation issues of hydrogen gas can be solved, the biggest obstacle to the widespread adoption of hydrogen energy will be overcome. Hydrogen gas, like natural gas, is a high-energy, highly flammable gas, and they share a high degree of similarity in storage and transportation. Experience in natural gas storage and transportation can provide valuable references and insights for the development of hydrogen gas storage and transportation. The equipment used for natural gas storage and transportation also provides a platform for experimentation in hydrogen gas storage and transportation. There are already research achievements in hydrogen gas storage based on natural gas storage, such as hydrogen blending in natural gas storage. The study of hydrogen gas storage and transportation is a glorious task entrusted to professionals in the storage and transportation industry by the nation and the times. Hydrogen gas transportation will become one of the important future directions for the storage and transportation industry. As future professionals in the storage and transportation industry, we should look to the future, recognize the enormous potential of hydrogen energy, and understand the current difficulties and challenges it faces.Abstract: As global energy demand continues to grow, and environmental awareness increases, traditional fossil fuels are no longer able to meet humanity's aspirations for a better life and the pursuit of environmental protection.
