A middle/lowtemperature coal tar (M/LTCT) was obtained from a lowtemperature carbonization plant in Shaanxi, China. The M/LTCT was separated into light components and coal tar pitch through extraction. A series of alkanes, aromatic hydrocarbons, oxygencontaining arenes (OCAs), and nitrogencontaining arenes were fractionated from light components by mediumpressure preparative ...

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...

Pulverised coal injection (PCI) is used in ironmaking to replace expensive and energy intensive coke with coal, reducing overall costs and greenhouse gas emissions. As the coke making process removes some of the sulphur present in coal, the utilisation of PCI results in the admission of greater levels of sulphur into the blast furnace.
