An open-bottomed cyclone separator with gas inlet tube is disclosed which minimizes the entrainment of separated solids in a process gas entering the separator. In some embodiments, the gas inlet tube directs the process gas into a solids-depleted region within a cyclonic separation chamber. In other embodiments, a gas inlet tube directs the process gas into a stream of solids-depleted gas withdrawn from the chamber. Methods for practicing the invention are also disclosed.

Open-bottomed cyclone with gas inlet tube and method

Open-ended cyclone separators are disclosed which employ catalyst separation tubes to prevent separated solids discharged through an open cyclone end from being entrained in a countercurrently moving flow of process gas entering the separator through the open end. In several preferred embodiments, generally conical tubes are axially located within the cyclone open bottom. Methods for practicing the invention also are disclosed.

Open-bottomed cyclone with solids separation tube and method

Methods for the recovery of bitumen from tar sands comprising the steps of mixing tar sand, solvent and a displacing amount of aqueous medium to form a mixture, followed by separating a bitumen-rich solvent phase from the mixture and recovering bitumen from the bitumen-rich solvent phase are disclosed.

Methods of tar sand bitumen recovery

A method for the recovery of bitumen from tar sand comprises slurrying tar sand with about 0.5 to about 4.0 pound of a organic solvent per pound of tar sand, then adding greater than about 0.50 pound water per pound of tar sand, and separating a bitumen rich solvent phase. The method has the advantage of permitting separation of sand from the bitumen rich solvent extract without formation of a stable emulsion.

Method for solvent treating of tar sands with water displacement

A method for recovering upgraded liquid products by the hydroconversion of coal, coke, lignite, petroleum fractions, biomass, tar sands bitumen and shale oil are disclosed. In particular, the catalyst composition employed consists of a Group VIB metal component and a highly dispersed tin component.

Hydrocarbon conversion method

A catalyst containing molybdenum and chromium and method for recovering upgraded liquid products from a solid carbonaceous material using said catalyst are disclosed.
