An engine control system configured to operate an engine is configured to predict an expected duty cycle including an expected demand from the engine, and calculate two or more future operating conditions, each future operating condition including engine control parameters that, when used to control the engine, are expected to result in the engine meeting the expected demand. One of the future operating conditions is selected, and a present operation of the engine is adjusted in response to the selected future operating condition. A vehicle and/or offroad diesel apparatus may comprise the engine control system.

Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.

A diesel oxidation catalyst article is provided, which includes a substrate carrier having a plurality of channels adapted for gas flow and a catalyst composition positioned to contact an exhaust gas passing through each channel. The catalyst composition includes a platinum (Pt) component and a sulfur (S)-containing component impregnated onto a refractory metal oxide support and is effective to abate hydrocarbon and carbon monoxide, as well as oxidize NO to NO.sub.2 in the exhaust gas. Methods of making and using the catalyst article are also provided, as well as emission treatment systems comprising the catalyst article.

The present invention disclosed preparation method of a visible-light-driven CC@SnS.sub.2/SnO.sub.2 composite catalyst, and application thereof, comprising the following steps: preparing CC@SnS.sub.2 composite material in a solvent by using SnCl.sub.4.5H.sub.2O and C.sub.2H.sub.5NS as raw materials and carbon fiber cloth as a supporting material; calcining said CC@SnS.sub.2 composite material to obtain the visible-light-driven CC@SnS.sub.2/SnO.sub.2 composite catalyst. The present invention overcomes defects of the traditional methods of treating chromium-containing wastewater, including chemical precipitation, adsorption, ion exchange resin and electrolysis, and the photocatalytic technology can make full use of solar light source or artificial light source without adding adsorbent or reducing agent. In this case, the use of semiconductor photocatalyst to convert hexavalent chromium in chromium wastewater into less toxic and easily precipitated trivalent chromium greatly reduces the cost and energy consumption.
