Abstract

The effect of the composition of resin and asphaltene on the quality of products obtained from delayed coking was evaluated. 10 mixtures with a controlled composition of S.A.R.A. (Saturates, Aromatic, Resin, Asphaltene) fractions with high percentage of resin and asphaltene, from a vacuum residue of Venezuelan crude commercially known as “Mereyâ€, were processed in a delayed coking unit at laboratory scale. The physic-chemical characteristics of the mixtures and products (distilled and coke) were obtained. Results indicate that on increasing the resin and asphaltene content, there is a decrease in the content of volatile material and an increase in fixed carbon and ash. Metal and sulphur content were found in a lesser proportion in coke from the mixtures rich in resin while said content was higher for the mixtures rich in asphaltene. This showed the impact that the S.A.R.A composition of the feed has on the quality of the products obtained.
