Abstract

PROCESSO DE COQUEIFICAçãO RETARDADO. A invenção refere-se a um processo de coqueificação retardado para fazer coque de fluxo substancialmente livre, preferivelmente coque granular. Uma carga de alimentação do coqueificador, tal como um resíduo de vácuo, é aquecida em uma zona de aquecimento até temperaturas de coqueificação, então conduzida para uma zona de coqueificação, em que os voláteis são coletados pelo topo e coque é formado. Um aditivo de baixo peso molecular é adicionado à carga de alimentação antes dela ser aquecida na zona de aquecimento, antes de ser conduzida para a zona de coqueificação, ou ambos.DELAYED COOKING PROCESS. The invention relates to a delayed coking process for making substantially free flowing coke, preferably granular coke. A coke feed charge, such as a vacuum residue, is heated in a heating zone to coking temperatures, then conducted to a coking zone, where volatiles are collected from the top and coke is formed. A low molecular weight additive is added to the feedstock before it is heated in the heating zone, before it is brought into the coking zone, or both.
