Abstract

"PROCESSO PARA A REDUçãO DE COQUEIFICAçãO EM REATORES DE CRAQUEAMENTO". A presente invenção refere-se a um método para a redução de coqueificação nas paredes de metal de um reator de craqueamento de hidrocarbonetos ou de outros compostos orgânicos e nas paredes de metal de um permutador de calor disposto a jusante ao reator de craqueamento, com o que as superfícies de metal que entram em contato com a substância orgânica a ser craqueada são pré tratadas com uma corrente de vapor de água que contém pelo menos silício e pelo menos um composto de enxófre.
