IPC: F01N13/02
Filed: 1997-12-08
Abstract: A method for exhaust gas purification by the use of a system for exhaust gas purification, which system includes (a) an adsorbent containing an adsorbent component capable of absorbing hydrocarbons present in the exhaust gas emitted from an internal combustion engine, provided in the exhaust pipe of the engine, (b) at least one catalyst containing a catalyst component capable of reducing harmful substances present in the exhaust gas, provided in the exhaust pipe at a site upstream of the adsorbent in the flow direction of the exhaust gas, (c) at least one catalyst containing a catalyst component capable of reducing harmful substances present in the exhaust gas, provided in the exhaust pipe at a site downstream of the adsorbent in the flow direction of the exhaust gas, (d) a first inlet for introduction of secondary air into exhaust gas, formed in the exhaust pipe at a site upstream of the most downstream catalyst of the catalyst (b), and (e) a second inlet for introduction of secondary air into exhaust gas, formed in the exhaust pipe at a site between the catalyst (b) and the most downstream catalyst of the catalyst (c).  The method includes introducing secondary air from the first inlet for a period from engine start to the activation of the catalyst (b) provided upstream of the adsorbent; at the timing when the catalyst (b) has been activated, stopping the introduction of secondary air from the first inlet; mean-while, introducing secondary air from the second inlet while the hydrocarbons of exhaust gas adsorbed by the adsorbent (a) are desorbed from the adsorbent (a) with the temperature rise of the adsorbent (a) brought about by the heat of the exhaust gas.  This method for exhaust gas purification can effectively purify the hydrocarbons discharged from an internal combustion engine in a large amount during the cold start, without adversely affecting the purification of NOx also discharged.

Title: Method for recovering nickel hydrometallurgically from two different nickel mattes
Inventor: FUGLEBERG SIGMUND PEDER
IPC: C22B23/00
Filed: 1996-08-06
Abstract: The invention relates to a method for recovering nickel in one and the same process from two pyrometallurgically produced nickel mattes, one of which contains a remarkable percentage of iron. The leaching of iron-bearing nickel matte is carried out in one step by conducting solution from the leaching cycle of a less iron containing matte into the leaching of a more iron containing matte at a stage where the iron of the less iron containing matte is in soluble form. The iron contained in the mattes is advantageously precipitated as jarosite and the solution created in the leaching of the more iron containg matte is conducted back into the leaching cycle of the less iron containing matte.
