Abstract: A method for controlling elevator cars of an elevator system according to one example includes assigning free elevator cars of the elevator system to one of either general service or express priority service (EPS). A destination dispatch controller receives an express priority service (EPS) call. The EPS call can indicate a request for priority service from an EPS call originating location to an EPS call final destination. The controller can determine whether any active EPS assigned car can service the EPS call. A particular elevator car can be an active EPS car when the particular car is carrying out EPS service. When a specific active EPS car can service the EPS call, the controller assigns the specific EPS car to the EPS call. Upon completion of the EPS call, the controller unassigns the EPS car to a free car.

Abstract: Disclosed is a process for completely destroying oxygenates in a feed stream. The feed stream of oxygenates typically includes olefins and it is reacted with hydrogen over a catalyst comprising a top row of Group VIII metal and a Group VI-B metal. Olefins are essentially completely saturated and any sulfur compounds present in the feed are completely converted to hydrogen sulfide. A preferred catalyst includes 2 to 5 wt-% nickel, 5 to 15 wt-% molybdenum, at least 5.5 wt-% sulfur, less than 0.05 wt-% phosphorus and no more than 0.3 wt-% silicon. The catalyst has low acidity and therefore does not promote the cracking of desired oligomeric products. The deoxygenation process is preferably a saturation process that follows an oligomerization process in which light olefins are oligomerized to heavy olefins. The saturation catalyst preferably has lower acidity which causes minimal cracking of desired oligomeric products.
