Abstract

Coking is obtained from the Moroccan refinery, which has mainly experienced a serious problem of the coking formation inside packed beds columns. The calcined petroleum coke properties need to meet the specifications for aluminum anode-grade coke. The aim of the present paper is to evaluate the physical-chemical characteristics of coking formed inside petrochemical distillation columns before and after thermal treatment. Coking undergoes additional thermal processing to produce calcined coking. Coking properties evaluated are: carbon, hydrogen, nitrogen, sulfur, metals (Cu, Cr, Zn, Fe, V, Mo, Zr, W, Mg), weigh loss, real density, and calorific value. The results of this study confirm that the calcined coking can be used as a good material for making carbon anodes.

焦化的理化性能和热处理评价

摘要

焦化来自摩洛哥的炼油厂,该炼油厂主要经历了填充床塔内结焦的严重问题。煅烧石油焦的性能需要满足铝阳极级焦的规格。本文的目的是评估热处理前后在石化蒸馏塔内形成的焦化的物理化学特性。焦化经过额外的热处理以产生煅烧焦化。评估的焦化性能为:碳,氢,氮,硫,金属(铜,铬,锌,铁,钒,钼,锆,钨,镁),重量损失,实际密度和热值。这项研究的结果证实了煅烧焦化可以用作制造碳阳极的良好材料。
