Method for converting oxygenates to olefins

   
   

The present invention provides a method for converting a feed containing oxygenates to olefins and comprises the following steps: providing a feed including an oxygenate; contacting the feed in a reactor apparatus with a catalyst including a molecular sieve, the contacting taking place under conditions effective to convert the oxygenate to a product including a light olefin, the conditions including a gas superficial velocity of at least two meters per second at at least one point in the reaction zone; and recirculating a first portion of the catalyst to recontact the feed.

A invenção atual fornece um método convertendo conter da alimentação oxygenates aos olefins e compreende as seguintes etapas: fornecendo uma alimentação including um oxygenate; contatando a alimentação dentro um instrumento do reator com um catalizador including um sieve molecular, ocorrer contatando sob as circunstâncias eficazes converter o oxygenate a um produto including um olefin claro, as condições including uma velocidade superficial do gás ao menos de dois medidores por o segundo ao menos em um ponto na zona da reação; e recirculando uma primeira parcela do catalizador para recontact a alimentação.
