Abstract: A system for hydroprocessing a hydrocarbon feedstock having a first stage including one or more first reactors that may receive the hydrocarbon feedstock and convert the hydrocarbon feedstock into an intermediate product. The feedstock has a total chlorine (Cl) content greater than 3 parts per million weight (ppmw), and the intermediate product includes hydrogen chloride (HCl), ammonia (NH3), and an ammonium salt. The system also includes a heating system having a plurality of heat exchangers arranged in a loop and having a heat transfer fluid that may recover and dispense heat to one or more fluids in the first stage. At least one heat exchanger of the plurality of heat exchangers is disposed between the first stage and a separation section, and the at least one heat exchanger may maintain a temperature of the intermediate product above a desublimation temperature of ammonia with hydrogen halide.

Abstract: A magnetoelectric composition of boron and chromia is provided. The boron and chromia alloy can contain boron doping of 1%-10% in place of the oxygen in the chromia. The boron-doped chromia exhibits an increased critical temperature while maintaining magnetoelectric characteristics. The composition can be fabricated by depositing chromia in the presence of borane. The boron substitutes oxygen in the chromia, enhancing the exchange energy and thereby increasing Néel temperature.
