Abstract

The invention relates to a liquid hydrocarbon composition containing an isoparaffin component. The liquid hydrocarbon composition is prepared from raw materials through processes such as pretreatment,adsorption separation and fractional distillation; through the process of fractional distillation, isoparaffin raffinate from the process of adsorption separation is firstly imported into an isoparaffin separation tower, materials extracted from a side tray of the isoparaffin separation tower flow into an isoparaffin side stripper, and the liquid hydrocarbon composition containing the isoparaffincomponent and having a flash point greater than 61 DEG C is obtained at the bottom of the stripper. The liquid hydrocarbon composition containing the isoparaffin component is simple in production process, high in yield, low in energy consumption, high in isoparaffin purity, free of naphthenic hydrocarbon, low in aromatic hydrocarbon content and narrow in distillation range.

Description

Technical field [0001] The invention belongs to the field of indirect coal liquefaction, and specifically relates to a liquid hydrocarbon composition containing isoparaffin components. Background technique [0002] Isoparaffins have strong solubility, and are colorless, odorless, and non-toxic. They are widely used in aerosol, stamping oil, cleaning, paint, ink and other industries. Among them, isoparaffins with a flash point greater than 61°C are especially suitable for metal processing, cleaning, coatings, polyolefin synthetic carriers, and peroxide carriers. They have a large market demand, and they are not part of the UN’s "Recommendations for Transport of Dangerous Materials" The flammable liquid substances in the "Standard Regulations" and "Hazardous Material Ship Transportation and Storage Regulations" are not classified as dangerous goods and are convenient to transport. [0003] The isoparaffins currently on the market mainly come from imported ExxonMobil’s Isopar series ...
