Chemical company develops locked cellulosic ethanol

Since the beginning of this year, international oil prices and grain prices have skyrocketed. The grain-based biofuel industry, including corn ethanol fuel, is controversial all over the world. At the same time, people are increasingly clamoring for the introduction of non-food biofuels such as cellulosic ethanol, and the development of cellulosic ethanol has been formed globally. The industry expects the industry to have a market size of 75 billion U.S. dollars worldwide. Last week, several other companies said they would invest heavily in this area.
It is reported that DuPont, a subsidiary of Denmark, and Genencor, a subsidiary of Danisco of Denmark, have formed a 50:50 joint venture company, DuPont Danisco Cellulose Ethanol, to develop a global leader in low-cost cellulose. Ethanol technology and the use of this technology to build commercial production facilities.
The joint venture named DuPont Danisco Cellulose Ethanol will invest US$140 million, combining the advantages of DuPont pretreatment technology and Genencor's advanced enzyme technology, and will first develop fiber using corn straw and bagasse as raw materials. Ethanol production technology. Thereafter, cellulosic ethanol production processes using lignocellulosic feedstocks such as wheat straw, various energy crops, and other biomass feedstocks will also be developed.
DuPont said that the first test device using this technology will be built in the United States and is expected to be completed and put into operation in 2009. The company said that this technology is expected to be commercialized before 2012. At that time, the joint venture company will provide technical licenses to ethanol producers. Manufacturers can use this technology to retrofit existing ethanol plants to make them suitable for processing cellulosic feedstocks, while also using this technology to build cellulosic ethanol plants.
He Lide, CEO of DuPont, said: “With the current global surge in food and gas prices, it is imperative to develop sustainable biofuel technologies. The purpose of establishing a joint venture company is to cooperate through the two sides. , The development of sustainable biofuel technology, which is a variety of non-food resources as raw materials suitable for commercial promotion of cellulosic ethanol production technology."
In the same period, the two German companies, Southern Chemicals and Linde, also announced the formation of a joint venture in early May to develop second-generation biofuel technology based on crops that do not compete with others for food.
It is said that both parties will work on the development of biotechnology processes to produce ethanol fuel from cellulose-containing plants such as wheat and cereal straw, pasture and wood chips.
Southern Chemicals will provide the joint venture with its technology in biocatalysis and bioprocess engineering. Linde-KCA-Dresden, a subsidiary of Linde AG, will provide engineering experience in the fields of biotechnology and chemistry.
