Covestro pursues bio-based aniline
FOCUS 20 bn barrels more is anticipated to come out of the region. In the next four to five years, the global supply/demand for PE will likely remain balanced. Even though most of the products from Chevron Phillips Chemical's new unit will be for the US market, a share will be exported to the European and Asian market. Currently, the company is exporting PE for the South and Central America. The company's PE export from the new units will be around 20-25%. Ethylene products from the new cracker will be sold to the merchant market. Presently, the company is in discussion with potential partners for the creation of an on-purpose benzene project in the US using its Aromax process. The company's Aromax process converts naphthenes and light paraffins to toluene and benzene in a catalytic reformer. Chevron Phillips Chemical has two Aromax units, one in Pascagoula, MI, US and one in Saudi Arabia with its joint venture partner Saudi Aramco.

Convion SOFC for DEMOSOFC project uses renewable biogas In early Mar 2017, Convion started the trial run of its first biogas-powered solid oxide fuel cell (SOFC) unit in Espoo, Finland, under the EU-financed DEMOSOFC project. The unit has exhibited an over 55% electrical efficiency net AC operating on biogas. Together with exhaust heat recovery, the overall efficiency exceeds 82%. Various tests are now being performed at the pilot unit before its delivery to SMAT's a wastewater treatment plant in Collegno, Turin, Italy. The SOFC combined heat and power (CHP) system will be launched shortly, and begin producing electricity needed by the plant. Using biogas generated through anaerobic digestion with wastewater sludge, the fuel cells will supply around 30% of the treatment facility's electricity requirement and 100% of its thermal energy needs. DEMOSOFC is partly financed by the Fuel Cells and Hydrogen Joint Undertaking (FCH JU).

NEW TECHNOLOGY Covestro pursues bio-based aniline Covestro has demonstrated a method for the production of aniline from sugar.

According to the firm, the newly developed process uses a microorganism as a catalyst to first convert the industrial sugar into an aniline precursor. The aniline is then derived by means of chemical catalysis in a second step, leading to a product with an entirely biobased carbon content. For approximately five years, Covestro has been working on developing the method with the CAT Catalytic Center at RWTH Aachen University, Bayer and the University of Stuttgart. Covestro plans to refine the method in the laboratory while obtaining the data required for scale-up. Pilot-scale production is expected to start in 2020, followed by commercialization in mid2030.

New enzyme blends save costs and enable better detergents Novozymes has launched three new blends of its Medley solution for liquid laundry detergents. The enzyme blends are made to meet the needs of consumers in emerging markets. Novozymes' Medley range is tailored to different laundry habits around the world. Consumers want their laundry detergent to perform different tasks, from removing stains to preserving colours and fabric. For example, Europeans want colours to last longer, while consumers in Asia perceive cuffs and collars as being particularly difficult to clean. This is why Novozymes makes Medley available in multiple versions to accommodate different regional needs. Many detergents, especially in emerging markets, contain a lot of water and this reduces the effect of some enzymes. The enzymes in the new Medley blends have been developed by Novozymes' scientists to secure stability and consistent performance wash after wash in detergents with high water content.

Preparation and catalytic performance of activated carbon non-woven fabric Pt-based catalyst Researchers at Guangdong University of Technology, Key Laboratory of Clean Chemistry Technology of Guangdong Higher Education Institutions, Guangzhou Institute of Energy Testing, Jiangmen Coto Chemical Co Ltd and Zhongsan Ubest Technology Co Ltd have synthesized an integrated catalyst
through direct loading of noble metal platinum onto activated carbon nonwoven fabric. The catalytic performance of the prepared chemical has been investigated using catalytic degradation reaction of formaldehyde. Results of the study revealed that better degradation rate of formaldehyde at room temperature can be met by drying the activated carbon nonwoven fabric at 80 deg C and the noble metal content is 0.6%. The catalyst has good applicability when formaldehyde concentration of 1.397.34 mg/cu m.

Effect of cerium modified HZSM-5 catalysts on methanol-to-gasoline reaction Researchers at Hebei University of Science and Technology, Hydrology and Water Resources Bureau of Shijiazhuang City, Hebei Pharmaceutical and Chemical Engineering Technology Research Center and Maisen Energy Technology Co Ltd have determined the impact of cerium modified HZSM-5 catalysts on methanolto-gasoline (MTG) reaction. Various factors including the reaction temperature and system pressure on the MTG process were considered. Results of the study revealed that cerium modified HZSM-5 catalysts can maintain good MFI structure and boost the strength of Lewis acid. At 375 deg C reaction temperature, 1.0/h feed space velocity and 2.0 MPa system pressure, methanol can be completely transformed into gasoline. The yield of resulting gasoline would be more than 34%.

Experimental study on advanced treatment of refinery wastewater by ozone catalytic oxidation and biological aerated filter Researchers at East China Jiaotong University, JiangXi Zosin Environment Protection Project Co Ltd, and South China Sea Green Power Renewable Energy Co Ltd have conducted an experimental study on the treatment of refinery wastewater through biological aerated filter and ozone catalytic oxidation. Results of the study revealed that the system can eliminate COD, as well as NH3-N under certain conditions. The average effluent concentration is 2.07 mg/L for NH3-N and 44.1 mg/L for COD.
