Scope

This document specifies the technical requirements, test methods, sampling, inspection rules, and storage of carbon black feedstock oil refining catalytic slurry. This document applies to carbon black feedstock oil refining catalytic oil slurry.

Introduction

GB/T41957-2022 Standard Overview

This standard specifies the technical requirements, test methods, sampling, inspection rules and storage requirements for carbon black raw material petroleum refining catalytic oil slurry, and is applicable to special raw material oil required for carbon black production.

Technical Requirements Comparison Table

Test Items	Technical Indicators	Test Methods
Moisture (volume fraction)	≤0.5%	GB/T260
BMCI Index	≥110	GB/T18255 & Calculation Formula
Ash (mass fraction)	≤4%	GB/T2295

Background of Standard Formulation and Technological Evolution

With the development of the carbon black industry, the quality requirements for crude oil are becoming increasingly stringent. The formulation of this standard aims to standardize the technical indicators of petroleum refining catalytic oil slurry to ensure its suitability for the carbon black production process and meet the requirements of environmental protection and safe production.

Practical Application Case Analysis

When using the GB/T41957-2022 standard, a carbon black production company found that the BMCI index of its crude oil did not meet the requirements. By optimizing the refining process and adjusting the catalyst ratio, the BMCI index was successfully increased to 115, significantly improving the quality of carbon black products.
