摘要
中低温煤焦油作为重要的化工初级产品,在有利补充石油资源、强化能源综合保障能力方面具有重要战略意义.本文综述了中低温煤焦油蒸馏/精馏、溶剂萃取(超临界萃取)、柱层析、低温共溶等分离方法发展现状与技术优势,并强调了在中低温煤焦油加氢/催化裂化技术中催化剂的设计制备与匹配问题是其工业化核心技术问题之一.
Abstract
As an important primary chemical product,medium-low temperature coal tar plays an important strategic role in supplementing petroleum resources and strengthening comprehensive energy security ability.In this paper,the development status and technical advantages of coal tar separation methods such as distillation/rectification,solvent extraction(supercritical extraction),column chromatography and low temperature co-solution are reviewed.And it is emphasized that the design,preparation and matching of catalysts in coal tar hydrogenation/catalytic cracking technology is one of the core technical problems in industrialization.
