Abstract: We provide a process for producing high quality gasoline blending components, comprising: a) operating an alkylation reactor in an alkylate mode wherein a gasoline blending component is made having a RON of 90 or higher; and b) operating the alkylation reactor in a distillate mode wherein a second gasoline blending component and a distillate product is made, and wherein the second gasoline blending component has a RON of 85 or higher. Also, we provide an alkylation process unit, comprising: a control system connected to an alkylation reactor, that enables the alkylation reactor to operate in both an alkylate mode that produces a gasoline blending component having a RON of 90 or higher and in a distillate mode that produces a second gasoline blending component having a RON of 85 or higher.

Abstract: A high efficiency light emitting diode power supply for roadway lighting fixtures is provided. The power supply enables conditioning and monitoring of input power and monitors LEDs current to ensures consistent performance of the LED by changing a power correction factor. The LED output can also be adjusted based upon age or external input parameters and by modifying the power correction factor value. In addition, the LED output can be dimmed, turned down in output to a lower level at any time of night for a prescribed duration in order to further save energy. This dimming function uses a programming scheme that keeps track of the “seasons” (summer, fall, winter and spring) so that time of night is tracked accurately all year long.

Abstract: A lighting fixture and power supply are provided that allows a power factor correction (PFC) single ended primary inductance controller (SEPIC) that provides a controlled voltage output to provide a constant current to an LED load. The power supply provides an efficient and stable power supply for LEDs. Multiple power supplies can be provided on the same printed circuit board to control multiple LED channels.

Abstract: A process comprising adjusting a level of conjunct polymers in an ionic liquid catalyst between a low level that favors production of C5+ products boiling at 137.8° C. or below and a higher level that favors production of both C5+ products boiling at 137.8° C. or below and C5+ products boiling above 137.8° C.; wherein the adjusting is done in response to market demand. A process unit, comprising a reactor that operates with an ionic liquid catalyst comprising a low level or a higher level of conjunct polymers, and the alkylation reactor is switched between operating with the low and the higher levels in response to market demand. A process unit, comprising a reactor that operates in an alkylate mode and a distillate mode, and a catalyst regenerator that operates with varying severity to adjust the level of conjunct polymers in response to demand for gasoline or distillate.

Abstract: A process for producing hydrocarbon products, comprising: a) operating a process unit in an alkylate mode wherein greater than 50 wt % of a C5+ hydrocarbon stream from the process unit boils at 137.8° C. or below, b) adjusting one or more process conditions in the process unit, and c) after the adjusting step, operating the process unit in a distillate mode wherein greater than 50 wt % of the C5+ hydrocarbon stream from the process unit boils above 137.8° C. Also, a process unit, comprising: a) an alkylation reactor; and b) a control system that enables the alkylation reactor to be operated in the alkylate mode and in the distillate mode; wherein the alkylation reactor can switch back and forth from operating in the alkylate mode to the distillate mode.
