Abstract
PROCEDIMIENTO PARA LA SEPARACION DE ACETILENO DEL PRODUCTO RESULTANTE DE LA DISOCIACION TERMICA DE 1,2-DICLOROETANO POR HIDROCLORACION DE ACETILENO. EL PRODUCTO DE LA REACCION SE DESCOMPONE EN UN FLUJO DE PRODUCTO LIQUIDO Y OTRO DE PRODUCTO GASEOSO. ESTE, CONTENIENDO EN SU MAYOR PARTE EL ACETILENO RESULTANTE DEL PROCESO DE PIROLISIS, SE CONDUCE POR ENCIMA DEL LECHO CATALIZADOR E TEMPERATURAS COMPRENDIDAS ENTRE 50 C Y 200 C Y PRESIONES DE 8 HASTA 20 ATM. A CONTINUACION SE PASA A LA COLUMNA DEL CLORURO DE HIDROGENO QUE CONTIENE UN CATALIZADOR DE HIDROCLORACION TRADICIONAL, TAL COMO CLORURO DE MERCURIO SOBRE CARBON ACTIVADO. EL LECHO DE CATALIZADOR CONTIENE METAL NOBLE EN FORMA METALICA, DE OXIDOS Y/O DE CLORUROS.
