Pyrogen and Goodyear jointly develop the productio

  • Detail

Genencor and Goodyear, a subsidiary of Danisco, have jointly developed the production of bioisoprene from sugar. On march25,2010, the two companies announced the formation of a consortium to develop an integrated fermentation, recovery and purification system for the production of bioisoprene from renewable raw materials for tire manufacturing. Genenco said it would commercialize the technology in the next five years

natural rubber is added to the world's large-scale synthetic rubber, which is mainly used to produce tires with the core of improving the independent innovation ability of the plastic processing industry. Isoprene, an important precursor of some types of synthetic rubber production, is a highly volatile hydrocarbon, which is typically obtained as a by-product of crude oil refining. Isoprene monomer can be polymerized with catalyst to produce polyisoprene. Polyisoprene is used as raw material for tire and other materials. Excellent quality

the technical challenge of producing isoprene from renewable sources such as biomass is to develop efficient processes to convert carbohydrates to isoprene. At the 239th meeting of the American Chemical Society, Joseph McAuliffe of genenco introduced how the company can effectively convert sugarcane, grain, grain cob, seasonal forage or other biomass into isoprene by using genenco engineered bacteria, and how to make a good combination of fermentation and recovery processes to develop a new path for the preparation of synthetic rubber, an important component

the key point of this work lies in the optimization of the metabolic path, which deoxidizes the carbohydrate matrix to form 5-carbon isoprenoid precursor 3,3-dimethylallyl pyrophosphate (dmapp), which is then converted into biological isoprene products through the catalytic reaction of the enzyme isoprene synthase

the report indicates that this process can produce more than 60 g/l of bioisoprene monomer under fermentation. On the whole, the process shows the potential of using the combination of biology and process engineering to convert carbohydrates into valuable chemicals

Goodyear and other large tire manufacturers use isoprene to produce PDS System (formerly known as percudyn system) (Figure 4) in a different way from the above systems. Synthetic rubber (isoprene rubber) can be used as a substitute for natural rubber durometer when used in tires. In addition, isoprene can be used in a wide range of other industrial applications, such as: in other elastomers; Production of block copolymers such as styrene isoprene styrene (SIS) for hot melt adhesives; Surgical gloves and other rubber based products

as of March2010, the world's total production of high-purity isoprene from petroleum based raw materials was about 1.7 billion pounds (7.718 million tons). Goodyear manufactures 200million tires a year, becoming the world's largest isoprene user. The company has planned to use bio isoprene products to replace its consumption of petroleum based isoprene
