Abstract

The performance of steady-state flow ultrafiltration membrane reactors can be considerably increased by improving their hydrodynamic characteristics. A tubule recycle membrane reactor was designed and constructed. This type of reactor approximates plug flow behavior and uses few movable parts in addn. to a small membrane area. The performance of a pilot scale tubular recycle membrane reactor was verified for the hydrolysis of lactose using lactase [9031-11-2] from Aspergillus niger. The operational stability of the lactase during a long-term operation of the reactor was estd. The substrate employed for this purpose was a deproteinized, fermented lactic acid whey, the base for a non-alc. drink. [on SciFinder (R)]

Nuclear reactor

A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating.

Chemical reactor

A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple aspects of chemical engineering. Chemical engineers design reactors to maximize net present value for the given reaction.

Breeder reactor

A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be fuelled with more commonly available isotopes of uranium and thorium, such as uranium-238 or thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use.
