Abstract: Modified lignin products, processes for making them, and their use to produce rigid polyurethane or polyisocyanurate foams are disclosed. The processes comprise heating a lignin source with a nitrogen source and a starved concentration of a C1-C5 aldehyde to give a reaction mixture comprising a Mannich condensation product, neutralizing the reaction mixture, and isolating the modified lignin product. The process is performed at a mass ratio of lignin source to nitrogen source within the range of 1:1 to 1:5 and at a molar ratio of nitrogen source to C1-C5 aldehyde within the range of 3.5:1 to 1:1. Polyol blends and performance additives that contain the modified lignin products are described. Rigid foams that process well and incorporate up to 60 wt. %, based on the amount of polyol component, of the modified lignin contribute to excellent flame retardancy and low-temperature R-value performance.

Abstract: The present application discloses systems and methods related to protection of a reactor in an alternating current (AC) electric power system. In one embodiment, a system may include a protective action subsystem to implement a protective action based on identification of a fault condition associated with a reactor.

A supervisory subsystem may restrain implementation of the protective action when the frequency is outside of the range or when the change in the frequency is associated with de-energization of the line in electrical communication with the reactor.
