naphtha or kerosene desulfurization. HR 426, a promoted cobaltmolybdenum catalyst, is ideal for ultralow sulfur diesel production and is intended for US gas oil or Northern Europe diesel feeds having low-end points. HR 448, a promoted nickelmolybdenum catalyst, provides high hydrogenation activity with high desulfurization, and is designed for VGO, FC feed pretreatment, and firststage hydrocracking. HR 468 is offered as a substitute to HR 426 or HR 488 and is suitable for very or ultra-deep desulfurization of diesel.
Management will contribute its recycling technologies, process capabilities, and recovered metallic commodities, and Westbury Metals will contribute its sales force and commodity distribution capabilities. Westbury Metals will additionally market KBF Pollution Management’s hazardous waste recycling services to its existing customers in the electronics, chemical, aerospace, and metal finishing industries. KBF Pollution Management expects to be posting an estimated 25% increase in recycling service sales for 1H ended Jun 2002.

New method segregates high-sulfur gasoline Grace Davison and Sulzer Membrane Systems are designing S-Brane, a cost-effective method of producing ultra-low sulfur gasoline based on membrane separation. The process, aimed at light/intermediate boiling range gasoline, separates feed gasoline stream into two streams. One steam retains 70-85% of the inlet gasoline volume and shows a sulfur content of less than 30 ppm. The technology features a modular design, allows for long onstream times, and eliminates the use of fired heater as it operates at low temperatures. It also does not manifest recombination reactions, removes aromatics, and prevents octane loss. Hydrocarbon Processing, Jun 2002, 81 (6), 33-34
KBF executes jv KBF Pollution Management Inc has announced the execution of a jv agreement with Westbury Metals Group Inc (Westbury Metals). The jv represents KBF Pollution Management’s first major investment in the distribution of the metallic commodities it mines from industrial hazardous wastes with its patented technologies. KBF Pollution Management’s technologies costeffectively recycle, reuse, and mine hazardous industrial wastes – at the precise point of disposal, and are the only cost-effective and environmentally beneficial alternative to land disposal and incineration as of 19 Jun 2002. Under the terms of the agreement, KBF Pollution

Catalytic oxidation process recovers acetic acid from wastewaters Clean Japan Center has accorded Teijin Ltd of Japan an environmental award for the company’s process for recovering high-purity acetic acid from plant wastewaters. The process is being used for treating of 72,000 tonne/y of wastewaters from Teijin’s dimethyl terephthalate plant. The treatment plant recovers 2000-25000 tonne/y of 99.8% acetic acid for recycling from the wastewater. Chemical Engineering (New York), Jun 2002, 109 (6), 29

New process to dispose of refrigerator heat insulation. NKK has developed a technology to recover the CFC foaming agents from the urethane heat insulation of refrigerators. The process uses a heat medium bath to decompose the urethane and drive the CFCs into the exhaust gas. The urethane shrinks and can be used as feed for blast furnaces. The CFCs are decomposed and rendered harmless in a high-frequency heated catalytic degradation facility. Japan Chemical Week, 27 Jun 2002, 43 (2177), 11
PATENTS Platinum particles stabilised by polybetaines for fuel cell electrodes A platinum sol is treated with a protective colloid comprising a polymeric sulfobetaine, and added to a suspension of carbon black. The resulting platinized carbon particles are separated by centrifugation and then dried. US 6,391,818, 21 May 2002, Celanese Ventures GmbH, Germany
Upstart Catalytic Solutions shakes auto catalyst oligarchy
Epoxidation using pre-treated titanium zeolite
Catalyst Solutions Inc (CSI) has developed new catalyst technology which will reduce the loading of precious metals in automotive catalysts. The company is beginning to present a challenge to the major catalyst producers. The automotive catalyst market is dominated by OM Group (2001 sales $1.4 bn), Engelhard ($647 M), and Johnson Matthey ($535 M). CSI’s Mixed Phase catalyst technology incorporates perovskites and other metal oxides in a stable mixed phase structure. This reduces the need for platinum, palladium, and rhodium. A Bank of America Securities analyst has called the CSI threat ‘overblown’. Saloman Smith Barney also sees the drop in share prices as an over-reaction. CSI has raised venture capital of $40 M. It has been chosen by General Motors
Titanium zeolites in which some of the titanium has been leached out using a mixture of hydrogen peroxide and a chelating agent are superior epoxidation catalysts, producing less of the unwanted glycols and glycol ethers. US 6,417,378, 9 Jul 2002, Arco Chemical technology, Greenville, DE, USA
Nickel catalysts for oxidative dehydrogenation A very extensive patent, having 83 claims and 85 pages, presumably derived by a combinatorial process. The prime object is to convert ethane to ethylene. Preferred catalysts are nickel oxide containing a second metal oxide. US 6,417,422, 9 Jul 2002, Symyx Technologies Inc, Santa Clara, CA, USA
