disproportionation reactions, which allow the transformation of isobutylene into propylene. The firm intends to integrate Omega Plant into its Alpha Plant process to convert raffinates into propylene and BTX. The Alpha Plant process produces BTX (benzene, toluene, xylenes) blend from C4 and C5 raffinates. Chemical Engineering (New York), Jul 2004, 111 (7), 13 Cotton-processing enzyme Diversa Corp has unveiled an enzyme dubbed Cottonase designed to enhance the efficiency of processing cotton textiles. This enzyme is claimed to allow cleaning to occur at a lower temperature, with less alkali needed that may result in lower amount of wastewater generated. A synergy is said to be achieved between the enzymes and auxiliary chemicals already utilised for preparing yarn or fabrics for finishing, printing, and dyeing. Chemical Engineering (New York), Jul 2004, 111 (7), 15 Novel acrylics from Rohm and Haas Rohm and Haas will collaborate with CalTech in formulating catalytic polymerization technology for the manufacture of novel acrylics under a three-year project dubbed Project Columbus. The collaboration entails formulating and synthesizing new catalysts that are capable of controlling the molecular structures of acrylic polymers, then integrating the best features of acrylics into those of polyolefins. The US National Institute of Standards and Technology has granted a $2 M Advanced Technology Programme Award to Rohm and Haas for this initiative. High Performance Plastics, Aug 2004, 9 Sumitomo Chemicals: process for caprolactam Sumitomo has developed a non-acid catalytic process for making caprolactam, which avoids large quantities of ammonium sulfate by- product. The high-silica MFI zeolite catalyst is combined with a novel fluid bed reaction system. A 60,000 tonne/y plant, which began operation in 2003, consumes less energy and makes less waste.

The pilot project has been transferred to Guangzhou Guangzhong Enterprise Group Co Ltd and the 5000 tonne/y commercial production trial involving carbon dioxide degradable plastics is being jointly carried out. Several new catalysts have been developed, which are safe, low cost and involve simple preparation processes. A 500 litre pilot test polymerisation reaction demonstration production plant is being built.

The project aims to solve problems relating to the control of volatile industrial organic pollutants and the development of the combustion of natural gas and rare earth catalysing materials. So far a pilot production line has been set up and six industrial organic pollutant purifying projects have been progressed.

DAF, Iveco, Mercedes- Benz, Renault Trucks, and Volvo Trucks together represent approximately 80% of the European truck market. In parallel with this introduction, chemical and oil companies are safeguarding the regular supply of AdBlue, the water/urea solution necessary for SCR technology. By means of a catalytic converter with the help of metered quantities of AdBlue sprayed into the hot exhaust gas stream, SCR reduces harmful nitrogen oxides (NOx) into harmless nitrogen and water. AdBlue is the commercial name for a high quality, standardised 6 OCTOBER 2004 FOCUS ON CATALYSTS
