Metal supported powder catalyst matrix and processes for multiphase chemical reactions
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.
SYSTEMS AND METHODS FOR PREDICTING AND CONTROLLING THE PROPERTIES OF A CHEMICAL SPECIES DURING A TIME-DEPENDENT PROCESS
Devices and methods for controlling the properties of chemical species during time-dependent processes. A device includes a reactor for containing one or more chemical species of a time-dependent process, an extraction pump for automatically and continuously extracting an amount of the one or more chemical species from the reactor, one or more detectors for measuring property changes of the one or more extracted chemical species and generating a continuous stream of data related to the one or more property changes to the one or more chemical species during a time interval, and a process controller configured to fit the continuous stream of data to a mathematical function to predict one or more properties of the one or more chemical species at a future time point and make one or more process decisions based on the prediction of one or more properties at the future time point.
Actuator with port
An actuator is provided that includes a housing, a linear actuating shaft disposed within the housing, a piston coupled with the shaft, and a fluid barrier disposed on an end of the shaft and encircled by the piston. The piston is movable longitudinally between an extended configuration and a retracted configuration upon rotation of the shaft. The fluid barrier engages an inner surface of the piston preventing fluid communication across the fluid barrier. The fluid barrier has a shaft engaging side which receives the shaft and a fluid facing side. A cavity is formed between the piston and the fluid facing side and expands when the piston moves to the extended configuration and contracts when the piston moves to the retracted configuration. A port is disposed in the piston and extends from the cavity to external the piston thereby permitting fluid communication between the cavity and external the piston.
