Problems solved by technology

There are two types of carbon black production processes: oil furnace method and contact method, and there are different production processes in each category. The coexistence of these various production processes results in uneven quality of carbon black and great differences in production efficiency, especially The process of controlling the expected value of iodine absorption value of carbon black products in the production process of contact method is very immature

Embodiment 1

[0023] Embodiment 1: Preparation of C611 series carbon black products

[0024] combine first figure 1 To illustrate the technological process of the present invention:

[0025] (1) The raw oil from the anthracene oil storage tank 1 is pumped into the anthracene oil preheating tank 2 through the oil pump 3, and is quantitatively fed through the anthracene oil metering tank 4 into the preheating kettle 5 for preheating, and the preheating temperature is controlled at 160°C~ 200°C, and then enter the gasification kettle 6;

[0026] (2) Before the carrier gas from the coke oven gas tank 7 enters the gasifier 6, it passes through the gas pipeline and circles around the fire room 8 to make full use of the waste heat of the fire room for heating, and the temperature of the carrier gas is controlled at 450°C ~550℃, the pressure is controlled at 2000~2800Pa.

[0027] (3) In the gasifier 6, the raw material oil is gasified and mixed with the carrier gas. The temperature of the mixtur...

Embodiment 2

[0045] Embodiment 2: Preparation of C311 series carbon black products

[0046] This embodiment adopts figure 1 The shown reaction device and the above-mentioned reaction principle prepare C311 series carbon black products, comprising the following steps:

[0047] (1) The air enters the fire room through the adjustable dampers on both sides of the bottom of the fire room through the way of natural air intake. This air intake method does not require additional fans to save energy and is easy to adjust. Just adjust the damper at the bottom of the fire room;

[0048] (2) The 380kg / h raw oil is injected into the anthracene oil preheating tank through the oil pump, and enters the preheating tank for preheating through the quantitative feeding method of a given period of time. The preheating temperature is controlled at 180°C, and then enters the gasification tank.

[0049] (3) 200kg / h gas is carried around the fire room through its pipes, making full use of the waste heat of the fi...

Abstract

The invention discloses a carbon black product and a production method thereof, and more specifically relates to a controllable carbon black product capable of absorbing iodine with high efficiency, and a production method thereof. The carbon black product is composed of a raw material oil and a combustion gas; the raw material oil is anthracene oil, the combustion gas is coke oven gas, and weight ratio of the raw material oil to the combustion gas is 360-400:140-240. The production method belongs to gas-mixture channel-free black production method of contact black production technology. The product of the production method is color black, and possesses high fluidity, high blackness, and excellent tinting strength and glossiness.

Description

technical field [0001] The invention relates to a carbon black product and a production process thereof, in particular to a high-efficiency iodine absorption controllable carbon black product and a production process thereof. Background technique [0002] Carbon black is a general term including carbon black products for various purposes. Its definition is: carbon black is a highly dispersible black powder obtained by cracking and incomplete combustion of hydrocarbons (liquid, solid, gaseous hydrocarbons), It is mainly composed of carbon elements. There are two types of carbon black production processes: oil furnace method and contact method, and there are different production processes in each category. The coexistence of these various production processes results in uneven quality of carbon black and great differences in production efficiency, especially The process of controlling the expected value of iodine absorption value of carbon black products in the production pro...
