Compartmentalized reactor which makes possible the oligomerization of olefins to give linear olefins and preferably to give linear -olefins, comprising a reaction chamber and at least one heat exchanger(s). The compartmentalized reactor is also employed in an oligomerization process.

One embodiment provides a chemical reactor, which can comprise a substrate for facilitating chemical reactions occurring at triple-phase boundaries. One possible substrate may further comprise a set of dynamically controllable sites and/or pixels upon which control signals may affect a desired formation of gas bubbles over an active catalytic (or other desired) solid surface in a liquid flowwherein a chemical reaction in two or more phase boundaries may occur. In yet another embodiment, a control algorithm may send control signals to controllable sites/pixels to maximize the operation of the reactor according to a desired metric (e.g., product formation) that may input a set of sensor data to affect its control.

The present invention relates to a device for treatment of material transported through the device having a specific design.

A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

The present invention relates to a continuous flow hydrogenation process and process apparatus.

A process for cleaning a reactor, the reactor comprising a shell including catalyst for selectively converting hydrocarbons. The process includes removing catalyst from the reactor and deploying a robot into the reactor. A cleaner from the robot is applied onto a surface within the shell of the reactor that includes a foulant. The cleaner is adapted to remove the foulant from the surface within the shell of the reactor. The cleaner may be one of light radiation, heat radiation, ultra-high pressure fluid, and liquid nitrogen.

A recombinator for the catalytic recombination of hydrogen and oxygen generated in energy converters, in particular accumulators, to form water, comprising a housing in which a volume space is formed, into which the gases can flow via an opening and in which a recombination device is arranged that comprises a portion for a catalyst material and a portion for an absorption material, wherein the flow path of the gases to be recombined extends through the portion comprising the absorption material into the portion comprising the catalyst material, wherein a distance space is formed between the portion comprising the absorption material and the portion comprising the catalyst material, wherein the catalyst material is configured as a catalyst bar, the catalyst bar is arranged in a first gas-permeable tube and the distance space is formed in a gap space between the inner walling of the first gas-permeable tube and the outer wall of the catalyst bar.

Disclosed are methods and systems for hydrogen isotope exchange of organic molecules that can be carried out with no alteration in the chemical structure of the organic molecules. Methods can be utilized to incorporate a particular hydrogen isotope on an organic molecule (e.g., deuteration or tritiation) or to remove a particular hydrogen isotope from an organic molecule (e.g., detritiation).

The invention provides a method and a plant for producing urea ammonium nitrate (UAN). The method involves the use of a condensation section, optionally in combination with a medium pressure decomposition section, between the dissociation and neutralization sections. The invention further provides a method of modifying an existing UAN plant. The advantages of the process of the invention are that the emission of CO.sub.2 can be reduced, the plant capacity can be increased and the high capital expenditure needed for CO.sub.2 compression equipment is reduced.

The present invention relates to a continuous process for preparing chlorine and a production unit for carrying out said process. The present invention further relates to a use of said production unit for the continuous production of chlorine.
