review the achievements of global chemical science and technology in 2005

December 31, 2005

in 2005, with the development of global chemical production, the pace of technological innovation further accelerated, becoming an important guarantee for the sustainable development of the chemical industry. In the past year, the new progress of global chemical technology was mainly concentrated in the fields of basic raw materials and intermediates, synthetic resins and plastics, chemical production and environmental protection catalysts, biochemistry, nanotechnology, new chemical materials and chemical equipment. A series of new achievements with important innovation significance and promotion value and profound impact on the development of chemical industry and related industries have emerged one after another

new technology of raw materials accelerates industrialization

the ethylene production process srt-x newly developed by Loomis company has the characteristics of rapid heating and reducing coking, and the furnace area is reduced by 10%, and the cracking capacity is increased by 3 times. The capacity of this new type of furnace can be expanded to 300000 tons/year, and the investment can be reduced by 10%. The catalytic cracking process developed by Asahi Kasei produces propylene and ethylene from C4 and C5 extracts. The industrial scale unit built by the company in Shuidao, Japan, will be put into operation in early 2006

the polymer grade terephthalic acid process developed by Eastman has the characteristics of few steps, simple operation, high reliability and low production cost. The total investment is 25% - 30% lower than that of conventional PTA technology. The terephthalic acid plant constructed by Zhejiang Hualian Sanxin Petrochemical Company using this technology in Shaoxing has been put into operation in May this year. BASF and Dow Chemical will adopt the new process of producing propylene oxide through the no by-product hydrogen peroxide route, and build a 300000 ton/year plant in Belgium

new products emerge in the polymer field

sri consulting company launched a new batch process technology to produce polystyrene (PS) through anionic polymerization. The molecular weight distribution of PS produced by this process is much narrower than that of the existing technology, the strength and processability are improved, and the investment cost is reduced by 28%. Conductive thermoplastic materials can be widely used in color matching products, and the material consumption can be reduced by up to 45% in the production process. Diren chemical company has developed a new process that can completely recycle the waste polycarbonate resin, which reduces the energy consumption required to prepare bisphenol A from pure monomers by 66%

the polyhydroxyalkyl ester biopolymer of metabolix company in the United States can compete with PE in price and performance, and is expected to eventually replace 50% of traditional plastics. Cornell University in the United States found that plastic can be made from renewable resources and CO2. It has many characteristics similar to polystyrene (PS) and is biodegradable at the same time. The biodegradable plastic material developed by BASF combines the biodegradable ecoflex polyester and the biological plastic polylactic acid

catalyst technology promotes process innovation

Northwestern University has developed a metalloenzyme with membrane capsule structure for the reaction of methane to methanol. This research is conducive to the development of catalysts for the conversion of methane to methanol, which will enable this medical plastics forum to provide visitors with rich information and theme content. Natural gas replaces oil for the synthesis of useful fuels and chemicals. ExxonMobil Chemical Company has developed a new silicon aluminum phosphate molecular sieve catalyst for methanol to propylene, which has significantly improved its catalytic activity and solved the problem of too fast coking of the catalyst in the methanol to propylene process using methane as raw material

univation technology company has developed prodigybmc100 catalyst, which is used for high-density polyethylene film grade resin and pipe grade HDPE resin. The investment can be saved by 40% compared with the production scheme of multi reactor system. The new generation of fluidized bed catalyst developed by Swiss Longsha company is used in its proprietary process to produce maleic anhydride. Compared with the previous generation catalyst, the selectivity of this catalyst is 4% higher, and the operating temperature can be reduced to about 410 ℃. The butane conversion rate is maintained at 80% - 85%, and the high-end strategy is vigorously implemented

nanotechnology promotes new product development

oxonica developed envirox, a fuel additive based on nanotechnology, which is widely used in British cars by stagecoach group. The additive can reduce fuel consumption by 5% and vehicle emissions by 5%. BASF introduced ultradur highspeed nano polymer modified polybutylene terephthalate, which has been applied to the commercial production of wire sockets

Germany Southern Chemical Company successfully developed an anti-wear polypropylene/polystyrene plastic alloy with modified nano additives, which not only has high anti-wear performance, but also has uniform surface and good hand feel. Mitsui chemical company of Japan has developed a new kind of polyimide carbon nanocomposite, which is suitable for processing machines and tools for manufacturing semiconductors or components for hard disk drive that require a high-definition dynamic pendulum dynamometer with a load inducing mechanism enclosed in a glass hood for cleanliness

new materials add luster to high technology

NEC company in Japan has developed an ultra-thin rechargeable flexible polymer battery with a charging time of 30 seconds. This kind of flexible battery uses organic group polymer as cathode, which is small enough to be embedded in smart card and smart paper. British plasticlogic company has developed a 25.4cm flexible organic matrix display template with a resolution of 100ppi and a thickness of less than 0.4mm. Currently, 350mm × 350mm display templates will be available soon. The University of California has developed a low-cost plastic solar cell, which is expected to be produced at the cost of 10% - 20% of the traditional battery, which is the most efficient plastic solar cell so far

the University of Michigan has developed a kind of light and strong polymer, which is expected to be used to store hydrogen fuel. This covalent organic skeleton has a predictable crystalline structure, can be made into highly porous materials to increase its storage capacity, and is light in weight, which is more economical for vehicle transportation

unit equipment has become the backing of energy conservation

some innovative technologies have emerged in the operation of distillation unit, mainly including extraction distillation, reaction (or catalytic) distillation, split wall (DW) tower, and some process improvements, such as combined membrane technology, to improve the separation efficiency. By July, 2005, nearly 60 split wall towers had been put into operation. The process of combining the design of split wall tower and extraction distillation has been put into industrial application by Germany uud company

catalytic distillation technology company applies reactive distillation technology to desulfurization of gasoline, which can produce chemical reaction and distillation in the same tower. The company has transferred and applied to 25 units, with a total processing capacity of about 43 million tons/year of catalytic cracking (FCC) gasoline. The reactive distillation process developed by Sulzer chemical technology company and wacker chemical company can be applied to the hydrolysis of methyl acetate
