20100187156 | Sour service hydroprocessing for lubricant base oil production - An integrated process for producing lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or a high pressure separation can be used to partially eliminate contaminants. | 07-29-2010 |
20120184442 | Ultra Pure Fluids - The invention relates to hydrocarbon fluids having high purity with respect to at least one of sulfur species, nitrogen species, oxygenated species, and unsaturated species, particularly hydrocarbon fluids low in aromatics, a method of making said hydrocarbon fluids, a catalyst for use in said method, an apparatus whereby said method may be practiced, and uses of said fluids. | 07-19-2012 |

20160121315 | BASE STOCK PRODUCTION USING A HIGH ACTIVITY CATALYST - Methods are provided for using a dewaxing catalyst formed using at least two structure directing agents for production of a lubricant base stock. For example, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic production of lubricant base stocks. Additionally or alternately, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can provide improved aromatic saturation during processing of a feed for lubricant base stock production. | 05-05-2016 |

20090166251 | All catalytic medicinal white oil production - All catalytic process for producing white oils is provided. More particularly, medicinal grade white oils are produced from a process including hydrotreating and/or hydrocracking, catalytic dewaxing followed by hydrofinishing to produce a medicinal white oil. | 07-02-2009 |
20110180453 | Catalytic Dewaxing Process - In a catalytic dewaxing process, a catalyst comprising from 40 to 80 wt % of ZSM-48 having a silica to alumina molar ratio of less than 200:1 and from 0.3 to 1.5 wt % of a metal or metal compound from Groups 8 to 10 of the Periodic Table of the Elements is provided in a reaction zone. The catalyst is periodically contacted in the reaction zone under dewaxing conditions with a first hydrocarbon feedstock having a wax content of less than 50 wt % and with a second hydrocarbon feedstock having a wax content of 50 wt % or more. | 07-28-2011 |
