Abstract

"CATALIZADOR DE LEITO FLUIDIFICADO PARA A AMOXIDAçãO DE PROPILENO PARA ACRILONITRILA". A presente invenção está relacionada a um novo catalisador de leito fluidificado usado em um processo para a amoxidação de propileno para acrilonitrila. O catalisador compreende uma sílica como veículo e uma composição representada pelas fórmulas gerais a seguir: A~ a~B~ b~C~ c~Ge~ d~Na~ e~Fe~ f~Bi~ g~Mo~ h~O~ x~ Onde A representa pelo menos um elemento selecionado de um grupo composto por Li, K, Rb, Cs, Sm, em ou Tl; B representa pelo menos um elemento selecionado de um grupo composto por P, Sb, Cr, W. Pr, Ce, As, B, Te, Ga, Al, Nb, Tb, La ou V; C representa um elemento selecionado de um grupo composto por Ni, Co, Sr, Mn, Mg, Ca, Zn, Cd ou Cu e misturas destes; a é um número de 0,01 até 1,5; b é um número de 0,01 até 3,0; c é um número de 0,1 até 12,0; preferencialmente de 2 até 10; d é um número de 0,01 até 2,0; preferencialmente de 0,01 até 1,0; e é um número de 0,01 até 0,7; preferencialmente de 0,05 até 0,5; f é um número de 0,1 até 8; preferencialmente de 1,0 até 3,0; g é um número de 0,01 até 6; preferencialmente de 0,1 até 2,0; h é um número de 12 até 14, 5; X denota o número dé átomos de oxigênio que satisfaz às necessidades de valência dos demais elementos no catalisador; O conteúdo de sílica usado como veículo é de 30-70% em massa. o catalisador da presente invenção pode ser usado na reação para a amoxidação de propileno para acrilonitrila executada sob uma pressão de reação mais elevada e condição de carregamento mais elevada, e ainda pode sustentar um alto rendimento pós-reação de acrilonitrila.
