New oxidation catalyst for alcohols Workers at the University of Tokyo have developed a catalyst for oxidising alcohols to ketones or aldehydes using air or oxygen. The catalyst is ruthenium on alumina, suspended in trifluorotoluene. Turnover numbers of 1,000 have been achieved.

New route to fatty acid esters developed Sumitomo Chemical of Japan has come up with a new process for making fatty acid methyl esters without producing byproducts that could otherwise harm the environment. The process is based on the reaction of methanol with vegetable oil in a supercritical state. Conventional methods that use alkaline compounds to catalyse the methanol-vegetable oil reaction produce a byproduct soap component that must be removed. With the new process, the catalyst is easily removed to yield cost savings. Nitrogen and Methanol, Nov-Dec 2002, (260), 12

C94: Alternative PET catalyst Acordis Industrial Fibres has come up with C94, a new heavy metal-free catalyst intended for use in the production of bottles and textiles. The new polymer is a titanium-based catalyst having a similar thermal stability as common tin polymers. Applications in the industrial textile spinning and dyeing are claimed to be excellent, except for minor colour adjustments for certain applications.

Asahi Kasei develops mc route to ultrahigh mw PE

Iron catalyst makes hydrogen from water

Asahi Kasei has used metallocene catalysis to develop a UHMWPE. Market development has already started. This is the first time UHMWPE has been produced using metallocene catalysts. Asahi Kasei has been supplying conventional UHMWPE from a plant in Mizushima that was recently expanded to 4000-5000 tonne/y.

Uchiya Thermostat has developed a process for making hydrogen from water, at 200°, using an iron oxide catalyst. It should be suitable for making hydrogen for fuel cells, since no CO is produced. (It is unclear what the other product is – Ed.)

Improved LCP production process

Basell launches Spherizone process for PP Basell has reinforced its 6.8 M tonne/y position as world leader in PP production with the introduction of its new Spherizone process which could be adapted for production of PE and other polymers. Basell has been operating a Spherizone PP pilot plant at Ferrara and now plans to use the process at its 160,000 tonne/y PP plant at Brindisi. The Spherizone process is likely to replace the Spheripol process used in Basell’s PP plants at Tarragona in Spain and in jv plants in China and Iran.

Takasago to mass-produce materials for organic EL displays Takasago International Corp has developed an inexpensive manufacturing process which produces organic electroluminescent materials in half the normal number of steps and with fewer impurities. The technique is based on a proprietary catalyst, and the firm aims to have a commercial system of mass production ready by 2005. By that time, the market for products containing organic EL displays is

Sumitomo Chemical Co Ltd has come up with a new manufacturing process for LCPs that offer a highperformance material with better production efficiency. Flowability is enhanced while high heat resistance is preserved, with the reduced amount of low molecular weight LCP enhancing heat stability during moulding and lessening blistering during soldering. The novel technology employs a basic organic catalyst that boosts the rate of reaction between monomers while controlling unwanted side reactions. The catalyst reacts swiftly and does not remain in the polymer as it is removed from the reaction system through by-products during polymerisation. With the new technology, Sumitomo can double capacity to 4 kt/y at its existing LCP plant in Ehime, Japan. High Performance Plastics, Dec 2002, 9-10

No catalyst needed S-Brane, a polymer-membrane process for cutting sulfur in gasoline, will be tested in a 100-bbl/day demonstration plant starting in Jan 2003. WR Grace’s Davison Catalysts division of Columbia, MD, developed the process, which is expected to boost petroleum refiners’ compliance with the EPA’s 2005 Tier 2 requirement of less than 30 ppm of sulfur in gasoline. Touted as more cost-effective than other sulfurremoval technologies, S-Brane segregates a gasoline feed into two streams by pervaporation, with the fluid catalytic cracker (FCC) normally fed from streams emanating from atmospheric and vacuum distillation towers. Around 70-90% of the inlet gasoline volume is held by the retentate or clean product stream, which has a sulfur level of less than the stipulated 30 ppm. The retentate can be added immediately into the gasoline pool. The 10-30 vol % permeate contains the balance of the sulfur, which may be reduced through hydrotreatment and other traditional methods.

is a 1.4 mW Kawasaki unit that has been rebuilt to accommodate the new Xonon Cool Combustion system from Catalytica. The Xonon(R) system, which employs a catalytic combustor, helps provide the power plant with minimal NOx output levels – less than three ppm – which eliminates the potential for emissions-related restrictions. Through the use of a catalyst instead of a flame, the Xonon-equipped Kawasaki unit enables combustion at temperatures below that where NOx usually forms. Additionally, the Xonon Cool Combustion system makes it possible for Kawasaki to guarantee CO levels of less than 10 ppm and VOC levels of less than 2 ppm.

Tailgas treatment process KOs both N2O and NO Uhde GmbH has been able to formulate a catalytic method for eliminating N2O and other oxides of nitrogen from the tailgas from nitric acid plants. A catalyst test facility at the nitric acid plant has been able to obtain removal levels of as high as 90%. The new method involves

removing dinitrogen oxide and nitrogen oxide using an iron zeolite catalyst. The company reports that operating costs are the same compared to other tailgas nitrogen oxide treatment processes. In fall 2003, the firm aims to begin the operations of an industrial-scale demonstration facility that uses both processes in a single reactor.

Catalytic Solutions threatens autocat majors A novel automotive catalyst technology is expected to generate rapid sales growth at Catalytic Solutions Inc. According to analysts, the technology is a major threat to catalyst producers such as Engelhard and Johnson Matthey that account for the lion’s share of the $1.7 bn/y auto catalyst market. Shares in a number of auto catalysts suppliers fell this year following a report citing the threat from CSI’s technology. The so-called mixed-phase catalyst (MPC) involves a combination of several metals and metal oxides. The technology will enable auto makers to meet emission standards and will also allow dramatic reductions in costs because it uses 50-80% less platinum group metals than the normal technology.
