  • Method for the production of ethene and synthesis gas in circulating fluidized bed
    Patent number: 9216902
    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.

  • Process for producing light olefins from a feed containing triglycerides
    Patent number: 8513476
    Abstract: The process combines hydroconversion and catalytic cracking starting from a feed containing triglycerides, at concentrations of fatty acids above 85%, which maximizes the yields of light olefins, chiefly ethylene and propylene, while reducing the yield of gasoline, with conversion greater than 80 wt. %.
