DuPont LANXESS and others are marching into the field of biopolyolefins

with the increasing depletion of traditional petrochemical energy and the soaring cost of raw materials, countries' enthusiasm for the development of biofuels and bio based chemicals is gradually rising. After bio alcohols, biodegradable polyester, bio based surfactants and lubricants, the research on bio olefins has become the latest hot spot in the global biochemical industry. Goodyear, DuPont, LANXESS and other multinational companies have invested heavily in the field of biopolyolefins

bio isobutylene staged a project competition. French Global Bioenergy company, American Gevo company and German LANXESS company have increased their R & D efforts. The project competition of bio isobutylene is being staged

LANXESS and the US renewable chemical manufacturer jiwo are stepping up the commercial production of bio isobutylene, and the two companies have jointly developed bio isobutylene technology. Jiwo company is responsible for extracting isobutanol from sugar fermented from corn, and LANXESS is responsible for dehydration of isobutanol provided by jiwo to extract isobutene. Daniel Alexander Smith, who is responsible for the financial and commercial media relations of LANXESS, said: "as a shareholder and investor of giver, LANXESS uses all the bio isobutylene produced for the production of rubber. The experimental results show that the butyl rubber made from bio isobutylene meets the strict performance parameter requirements of the tire industry." Smith said that based on the current expectation, the bio butyl rubber produced by the company will reach 10000 tons in 2015

Christopher Ryan, President and chief operating officer of giver, said: "the challenge of producing isobutylene is to reduce the cost. Because the cost of isobutyl alcohol produced by us is much lower than that of traditional isobutyl alcohol, the biological isobutylene produced by it has obvious cost advantages." According to the plan, the production capacity of jiwo bio isobutanol will reach 11million gallons by 2013 and 35million gallons by 2015

(right 1) Thomas Buhl, business director of Richard Northcote Global Bioenergy company, said that isobutylene is the raw material for the production of polyisobutylene and butyl rubber, and has broad market prospects. At present, the global isobutylene market is about US $25billion, which is still expanding. The company plans to build a bio isobutylene pilot plant in 2013, an industrial demonstration plant in 2015, and commercial production from 2017 to 2018. "Bio isobutylene was selected as the first project not only because it can meet the growing demand of the rubber market, but also because it can be used for the preparation of isooctane." Bull said

bioisoprene investment is booming

at the same time, the field of bioisoprene is also attracting more and more investors. Earlier this year, DuPont, a pioneer in the field of biological chemicals, invested more than US $6 billion to acquire danysk company in Denmark. This is the largest transaction conducted by DuPont since 1999, which will benefit its biological isoprene business

Goodyear, an American synthetic rubber and tire manufacturer, is stepping up cooperation with genenco, a subsidiary of Danisco, to develop biological isoprene from sugar, and hopes to establish a complete set of integrated fermentation, recovery and purification system before 2015 to realize the commercial production of isoprene. Jesse roeck, Goodyear's director of global materials science, said: "by developing bio isoprene from sugars, it can be used to manufacture bio rubber, which not only has great commercial value, but also can reduce the dependence on petroleum derivatives and reduce the impact on the environment."

Richard Cilento, CEO of us glycos bio, estimates that the global annual demand for isoprene is about 850000 tons. In order to meet the growing demand of the Asia Pacific market, the company will establish an isoprene plant with an annual output of 2000 tons in Johor, Malaysia, to produce isoprene with crude glycerol as raw material. It is planned to start construction in the third quarter of this year and commissioning in the first quarter of 2013, Officially put into operation in 2014

biological butadiene is on the rise, but its performance can only be brought into play by computer servo system operation.

at the 6th ICIS olefin conference held in Belgium earlier this year, Christof krogmann, vice president of LANXESS petrochemical project, pointed out that at present, the research and development of biological butadiene is hot, and routes such as selective dehydrogenation to C4 olefins will attract more and more attention. He also explained several possible routes for the production of 1,3-butadiene, such as converting bioethanol to 1,3-butadiene through Lebedev reaction, converting bioethanol to butene and then converting to 1,3-butadiene through oxidative dehydrogenation, or converting 2,3-butanediol to 1,3-butadiene through dehydration process since the launch of national major science and technology projects for large aircraft in 2006

Global Bioenergy companies have tried and signed a cooperation agreement with synthos, the European rubber manufacturing leader, to develop a new biological butadiene process. "At present, the global annual output of butadiene is about 10million tons, of which 2/3 is used to manufacture synthetic rubber, and the rest is used to manufacture nylon, latex, ABS plastics and other polymers. It can be predicted that the butadiene market will be in short supply, which provides an opportunity for the new method to synthesize biological butanedienes," Buhl said
