Experimental study on the coal tar hydrocracking process over different catalysts

High-efficiency hydrocracking of phenanthrene into BTX aromatics over a Ni-modified lamellar-crystal HY zeolite

“…[28][29][30][31] Highperformance catalysts are the key for hydrocracking. 32,33 These hydrocracking catalysts usually contain two kinds of reactive sites. For instance, there are metal sites and acid sites on the surface of modified zeolite catalysts.…”

Study on the Preparation of Clean Liquid Fuel by Wide Fraction High-Temperature Coal Tar Deep Hydro-Upgrading on a Pilot Plant Trickle Bed Reactor

“…However, the supercritical process needs extremely harsh requirements for process equipment, greatly affecting its application in industry. Yuan and co-workers carried out experimental research on HTCT hydrocracking in a suspended bed reactor and showed that the catalytic system can greatly reduce the yield of gas and coke and effectively increase the yield of total liquid. , Majka et al studied the hydrocracking performance of coal tar in the reactor and believed that the NiW/Al 2 O 3 catalyst can promote the formation of light aromatics and the cracking activity of condensed aromatics.…”

Exceptional Aromatic Distribution in the Conversion of Palm-Oil to Biohydrocarbon Using Zeolite-Based Catalyst

“…Hydroprocessing is a resultant process of hydrogenation, hydrotreatment, and hydrocracking in which the oxygen atoms are eliminated in the presence of a very active catalyst under high hydrogen pressure. Although several noble metal-based catalysts have shown excellent activity [11,12], their finite availability and burdensome cost limit the utilization of hydroprocessing. Thermal cracking makes use of high temperature and pressure to convert palm oil into biohydrocarbons.…”
