An approach to inkjet printing of low-viscosity liquids is suggested consisting in suppression of undesirable weakly damped acoustic oscillations under the action of a double pulse. The duration and amplitude of the second pulse are adjusted so that the arising acoustic oscillations are in antiphase to those of the first pulse.
Thermodynamic parameters for the reactions of vacuum distillate catalytic cracking in a riser reactor have been calculated using the density functional theory. The list of the reactions has been compiled on the basis of laboratory studies on determining the group and structural-group composition of the vacuum distillate and the results of thermodynamic analysis. A kinetic model of the catalytic cracking...
