Abstract
UN PROCEDIMIENTO PARA AUMENTAR LA VELOCIDAD DE FILTRACION DE UNA SUSPENSION LIQUIDA DE CARBON PRODUCIDA EN UN PROCESO DE DISOLUCION DE COMBUSTIBLES HIDROCARBURADOS PROCEDENTES DE CARBON CON UN DISOLVENTE Y QUE CONTIENE LIQUIDO HIDROCARBURADO Y MINERALES DE CARBON SUSPENDIDOS. SE BASA EN REALIZAR LA FILTRACION EN PRESENCIA DE UN COPOLIMERO DE METACRILATO DE ALCOHILO Y UN ALCOHOL QUE CONTIENE DE 2 A 10 ATOMOS DE CARBONO QUE FORMA UNA COMPOSICION HOMOGENEA EN LA SUSPENSION DE CARBON. EL ALCOHOL SE AÑADE CUANDO LA SUSPENSION SE ENCUENTRA EN UNA TEMPERATURA COMPRENDIDA ENTRE 3 Y 371GC. I
