Abstract

aparelhos e processos aqui fornecidos para converter alimentações de hidrocarbonetos em olefinas leves e outros hidrocarbonetos. os processos e aparelhos incluem, em algumas formas de realização, alimentar um hidrocarboneto, um primeiro catalisador e um segundo catalisador para um reator, em que o primeiro catalisador tem um tamanho médio de partícula menor e é menos denso que o segundo catalisador. uma primeira porção do segundo catalisador pode ser recuperada como um produto de fundo do reator, e um efluente de hidrocarboneto craqueado, uma segunda porção do segundo catalisador e o primeiro catalisador podem ser recuperados como um produto de topo do reator. a segunda porção do segundo catalisador pode ser separada do produto de topo, proporcionando uma primeira corrente compreendendo o primeiro catalisador e o efluente de hidrocarboneto e uma segunda corrente compreendendo o segundo catalisador separado, permitindo o retorno do segundo catalisador separado na segunda corrente para o reator.
