A continuous process for producing hexafluoroisopropanol is provided which comprises contacting hexafluoroacetone with hexafluoroisopropanol and hydrogen to produce a liquid feed stream; introducing the liquid feed stream to a reactor containing an immobilized hydrogenation catalyst to convert the hexafluoroacetone to hexafluoroisopropanol and provide a product stream; and recovering at least a portion of the hexafluoroisopropanol from the product stream. Preferably a portion of the product stream is recycled. The reactor can be a packed bed or stirred tank reactor.

Continuous process to produce hexafluoroisopropanol

Hydrofluorocarbon production using heat carriers in high temperature

An improved process and apparatus are disclosed for fluidized catalytic cracking of hydrocarbons using a cross-flow or swirl type catalyst regenerator. Instead of a single catalyst withdrawal outlet for regenerated catalyst, multiple catalyst withdrawal points are provided. Use of multiple catalyst outlets, or a continuous radial catalyst outlet, greatly reduces stagnant regions in the bed.

Catalytic cracking apparatus using regenerator with multiple catalyst

An process and apparatus are disclosed for fluidized bed catalyst regeneration in a cross-flow type regenerator. A baffled coked catalyst inlet located within the dense bed of catalyst disperses and distributes coked catalyst flow in a direction generally normal to the direction of flow in the catalyst inlet. The baffle significantly reduces the stagnant regions in the bed.

Catalytic cracking process with multiple catalyst outlets

An improved process and apparatus are disclosed for fluidized catalytic cracking of hydrocarbons using a swirl type catalyst regenerator. Multiple, symmetrically spaced spent catalyst inlets are provided for addition of coked catalyst to the regenerator. Preferable a single catalyst outlet, for withdrawal of regenerated catalyst, is provided in the center of the regenerator. Use of multiple symmetrical inlets and a central catalyst outlet greatly reduce stagnant regions in the bed.

Catalytic cracking process using cross-flow regenerator

The waxy liquid phase of an oil suspension of Fischer-Tropsch catalyst containing dissolved wax is separated out and the wax is converted by hydrocracking, dewaxing or by catalytic cracking with a low activity catalyst to provide a highly olefinic product which may be further converted to premium quality gasoline and/or distillate fuel.
