AI Technical Summary

Technical Problem

Existing technologies are difficult to effectively convert greenhouse gases, especially CH4 and CO2, in the dry gas and flue gas produced by heavy oil catalytic converters, and the catalysts are prone to carbon buildup and deactivation, resulting in poor carbon emission reduction effects.

Method used

Inferior feedstock oil with a nickel content greater than 5 mg/kg is reacted with the catalyst in a heavy oil reactor to generate coking catalyst. After coking, the catalyst is regenerated by CO2 and O2 regeneration air. Part of the catalyst is returned to the heavy oil reactor, while the other part is reformed in a CO2 reactor with CO2-rich regeneration flue gas to generate high-value CO and H2.

Benefits of technology

It has achieved carbon emission reduction in the heavy oil catalytic unit, increased the yield of H2 and CO, reduced greenhouse gas emissions, simplified the process flow, and reduced investment costs.

Abstract

本发明提供一种基于劣重油催化装置碳减排的方法,包括:(1)使镍含量大于5mg / kg的劣质原料油和催化剂在催化剂密度为60~100kg / m3的重油反应器中反应;(2)使第一积炭催化剂进入再生器与包含CO2和O2的再生风接触进行烧焦再生;(3)一部分再生催化剂返回重油反应器中重复使用,另一部分再生催化剂经原料干气提升进入CO2反应器,之后与进入CO2反应器的富含CO2再生烟气接触进行重整反应。本发明以劣重油催化装置为核心,同一催化剂体系提供催化中心和热量载体,采用CO2循环的纯氧再生,实现了重油转化和CO2捕集转化两个目的,集合度高,实现低值气体高值利用的同时又可作为降低碳排放的核心,方法容易实施,投资成本低。
