Sludge petroleum charred slurry and preparing process and application thereof

Abstract

The invention discloses a sludge petroleum coke slurry and its producing method and application. Said sludge petroleum coke slurry contains 100-200 shares of petroleum coke by weight, 5-100 shares of moisture sludge by weight, 5-200 shares of water by weight, 0.01-2 shares of dispersant by weight, 0.01-2 shares of sludge modification reagent by weight. The produced high concentration sludge petroleum coke slurry can be a burning fuel or producing synthetic gas and hydrogen by gasification. It not only fully utilize the caloric caloricity in the sludge and gets over the problems that the present moisture sludge has a high heat treatment energy consumption and the offgas and dregs are harmful and poisonous and has a big industrialization prospect.

Description

technical field

[0001] The invention relates to a sludge petroleum coke slurry and its preparation method and application, in particular to a preparation method of high-concentration sludge petroleum coke slurry and its application. Background technique

[0002] The oil refining industry produces a large amount of petroleum coke every year. The main components of petroleum coke are hydrocarbons, and its low calorific value is about 1.5 to 2 times that of coal. With the increase of sulfur content in crude oil, the amount of high sulfur petroleum coke with sulfur content greater than 3% increases significantly. Direct combustion of high-sulfur petroleum coke will produce a large amount of SO 2 ; and directly used for gasification, although it can avoid the generation of SO 2 (generating H 2 S, easy to recover as sulfur), and due to the poor activity of petroleum coke, the fuel utilization efficiency is not high. At the same time, petroleum coke pulping has disadvantages s...
