Abstract

MéTODO PARA O MELHORAMENTO DAS PROPRIEDADES DE ESCOAMENTO DE UMA CARGA DE ALIMENTAçãO DE óLEO PESADO POR DIMINUIçãO DO SEU MóDULO ELáSTICO, E, MéTODO DE COQUEIFICAçãO RETARDADO. Um método para o melhoramento das propriedades viscoelásticas de um óleo pesado por alteração de seu módulo elástico. E usada uma quantidade eficaz de um ou mais agentes de diminuição de módulo elástico, em que os agentes de diminuição de módulo elástico preferidos incluem ácidos e bases minerais e orgânicos, de preferência bases fortes tais como hidróxidos de metais selecionados entre metais alcalinos e alcalino terrosos.
