Abstract
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.
