Multistability Control in Periodically Forced Catalytic Reactor
نویسنده
چکیده
A novel approach of the chemical reactor stabilization is proposed by using a multistability control. A creation of an additional stable steady state by changing the reactor multiplicity features is a main idea of the multistability control. Proposed approach employs a special type of periodic forced operation, called mediating operation. Mediating operation is able to change a qualitative character of the reactor dynamic behavior, particularly, to produce additional stable steady states in an intermediate temperature area. Feed ow rate is considered as a manipulated variable. Changing of CSTR multiplicity is investigated for two{step control inputs. It is shown that CSTR under two{step control can exhibit at most ve steady states having stable intermediate steady state. Two constructive procedures are proposed for nding out control parameters which provide a creation of the stable steady state in selected intermediate area.

Multivariable model predictive control of a catalytic reverse flow reactor
This paper is devoted to the multiple input multiple output (MIMO) model predictive control (MPC) of a catalytic reverse flow reactor (RFR). The RFR aims to reduce, by catalytic reaction, the amount of volatile organic compounds (VOCs) released in the atmosphere. The peculiarity of this process is that the gas flow inside the reactor is periodically reversed in order to trap the heat released d...

Although the operation under unsteady state is generally avoided and continuous operation is preferred in the chemical industry, this mode of operation can often lead to a better performance. Because of this, forced unsteady state reactors are object of increasing interest. In particular, the systems based on the periodic reversal of the feed flow direction, called reverse flow reactors (RFR), ...

Catechol-functionalized (salen)Mn complexes can be supported on mesoporous anodized aluminium oxide disks to yield catalytic membranes that are highly active in the enantioselective epoxidation of olefins when being deployed in a forced-through-flow reactor.
متن کاملHydrogen production by catalytic cracking of methane over nickel gauze under periodic reactor operation
The catalytic cracking of methane over nickel gauze is proposed as an attractive alternative for the production of CO-free hydrogen. The catalyst deactivates due to intensive coke deposition. Therefore, the reactor was operated periodically with the reaction followed by the catalyst regeneration by burning of coke in oxidative atmosphere. The optimal reaction performance was found to consist of...
متن کاملPeriod doubling in a periodically forced Belousov-Zhabotinsky reaction.
Using an open-flow reactor periodically perturbed with light, we observe subharmonic frequency locking of the oscillatory Belousov-Zhabotinsky chemical reaction at one-sixth the forcing frequency (6:1) over a region of the parameter space of forcing intensity and forcing frequency where the Farey sequence dictates we should observe one-third the forcing frequency (3:1). In this parameter region...
