20100058665 | Method for the production of ethene and synthesis gas in circulating fluidized bed - The present invention relates to a method for the production of ethene, CO, and hydrogen in a reactor with a circulating fluidized bed with two independent sections, from feedstocks that contain hydrocarbons with at least 11 carbon atoms or from feedstocks with a high oxygen content, using a catalyst in particulate form. The method teaches that in one of the sections of the reactor, in the absence of oxygen, a catalyst containing a dehydrogenation metal promotes the cracking of the said feedstocks, facilitating the subsequent endothermic reactions. In the other section, the coke is burned with air and the heating of the catalyst is controlled, for the adjustment of the appropriate amount of energy that the heated catalyst will convey to the section in which the endothermic reactions take place. The total ethene yield of the process according to the present invention is approximately 20% by weight in relation to the feedstock. | 03-11-2010 |

20080286182 | Combined Leaching Process - THE COMBINED LEACHING PROCESS comprises a dissolution process of the soluble constituents of an ore by means of the combined execution of two or more serial leaching phases with the first phase comprising atmospheric leaching (AL) and the second one pressure leaching (HPAL). This combined process takes place when the intermediate size fraction (0.075-0.5 mm) is submitted to atmospheric leaching (AL), ensuing an effluent with a high concentration of dissolved iron and aluminum as well as high residual acidity. This said effluent is fed in the following acid pressure leaching (HPAL) phase of the fine size fraction (<0.075 mm) and at reusing free acidity, regenerating the sulfuric acid through iron and aluminum precipitation in a hydrolysis reaction, and bringing forth a considerable reduction in the addition of sulfuric acid. | 11-20-2008 |
