.... Otherwise, catalyst would be deactivated, mechanical problems would occur and the catalyst circulation, which is fundamental to assure high conversion and good selectivity to noble products, would adjust itself to a very low value. These coolers usually remove heat from a catalyst stream withdrawn from...

... hydrotreaters. It is very effective for controlling the increase of the reactor AP caused by the deposition of iron sulfide in catalyst beds. NRC is a resid hydrotreating catalyst effective for controlling the dry sludge formation at high conversion. This catalyst, which was designed with consideration given...

Functionalization of methane via oxyhydrohalo- genation chemistry Co-produces halogenated methane...

.... High conversion hydroprocessing processes such as LC-Fining, H-Oil, Veba-Combi-Cracking (VCC), CANMET hydrocracking and INTEVEP-HDH use unique techniques to control the formation of coke. Examination of patent literature and other publications of these and other reported hydroprocessing processes show...

..., describes its demonstrated performance, and outlines recent technology improvements to reduce capital cost and improve product quality. This slurry hydrocracking process utilizes a solid additive to inhibit coke formation while obtaining high conversion to light products. Demonstration in a 5000 BPSD Unit...
