摘要
The object of the invention is a filtration and combustion process for carbon particulate matter from an internal combustion engine. The process is characterized by the following steps: a rare earth or rare earth mixture derivative is introduced into the fuel at a concentration of 10 ppm to 500 ppm (by weight), and preferably of 20 ppm to 200 ppm; the soot produced by the internal combustion engine is collected on a filter, the temperature of the gases entering the filter being selected in the range of 100 C. to 350 C.; the soot is allowed to build up until a significant fraction or rate of incoming soot is balanced by the combustion of soot in the soot cake on the filter, and no is effected as long as the head loss caused by the soot does not exceed a preselected value and is not higher than 400 millibars. This invention is useful for organic synthesis.
