... However, even today, oil thermal cracking technologies such as visbreaking and coking are used as important industrial processes. Visbreaking is a process that uses heavy petroleum fractions, such as residual oil from vacuum distillation of crude oil, as a feedstock, and thermally cracks them under relatively gentle temperature conditions (for example, 420-450°C) to produce gas, naphtha, cracked oil, cracked residual oil, etc. Its main purpose is to produce high-quality heavy oil fractions with low viscosity and pour point, and the name is an abbreviation of viscosity breaking. ... *Some of the terminology that mentions "visbreaking" is listed below.

… しかし,現在でもビスブレーキング法,コーキング法などの石油熱分解技術は工業的に重要なプロセスとして実施されている。ビスブレーキングvisbreaking法は,石油の重質留分,たとえば原油の減圧蒸留の残油を原料とし,比較的ゆるやかな温度条件(たとえば420~450℃)で熱分解し,ガス,ナフサ,分解油,分解残油などを生産するプロセスである。その主目的は,粘度や流動点の低い,良質な重油留分を生産することにあり,ビスコーシティ・ブレーキングviscosity breakingの略称として名づけられた。… ※「visbreaking」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
