Abstract A macroscopic model of two‐phase flow in packed beds, based on the volume‐averaged equations motion for gas and liquid phases, was analyzed an attempt to understand onset evolution fully‐developed pulsing trickle beds. By assuming that solutions take form waves travelling at constant speed, periodic these are found which can be associated with long‐time, asymptotic behavior pulses a very long bed. Families one‐dimensional exist particular set mass fluxes characterized by infinite...
Bond breaking and forming are essential components of chemical reactions. Recently, the structure formation covalent bonds in single molecules have been studied by non-contact atomic force microscopy (AFM). Here, we report details a dative bond process using AFM. The between carbon monoxide ferrous phthalocyanine was ruptured via mechanical forces applied microscope tips; quantitatively measured characterized both experimentally quantum-based simulations. Our results show that can be either...
Abstract A macroscopic model based on the volume‐averaged equations of motion is presented for countercurrent gas‐liquid flow in a packed bed. The yields column‐limited flooding point as loss existence uniform states. It correctly predicts two states below point. lower branch corresponds to trends commonly observed experimentally. shown that upper made unattainable by gas distributor/support plate at bottom column. occurrence premature induced support also explained. suggested spontaneous...
Copolymers of ethylene and 1-butene were synthesized using a single-site zirconium-based coordination catalyst. The polymers terminated exclusively in ends, predominantly ethylvinylidene. They carbonylated under Koch−Haaf conditions boron trifluoride, carbon monoxide, phenols to give polymeric hydrocarbons containing single carboaryloxy group. Both 1,3- 1,5-rearrangements observed this synthesis. amination reaction with polyethylene amines followed second-order kinetics, but steadily...
Abstract Bond breaking and forming is essential in every chemical reaction. Here, we report a single dative bond process revealing an unprecedented level of detail using noncontact atomic force microscopy. The between carbon monoxide ferrous phthalocyanine was ruptured via mechanical forces applied by microscope tips; the quantitatively measured characterized both experimentally first principles quantum mechanics modeling. Our results show that can be either applying attractive ~150 pN...
