Abstract: An integrated waste catalyst cleaning apparatus includes a reaction unit, an organic solvent unit, an organic acid unit, a drying unit, a condensation unit, a heating band, and control valves formed at transfer paths. The waste catalyst is injected into the reactor. The organic solvent stored in the organic solvent unit is to first-clean the waste catalyst. The organic solvent is discharged after cleaning. The waste catalyst is dehydrated and dried by the drying unit. The organic acid stored in the organic acid unit is to second-clean the waste catalyst. The organic acid is discharged after cleaning. The waste catalyst is dehydrated and dried by the drying unit.

Abstract: Disclosed is an integrated waste catalyst cleaning apparatus for residual hydro desulfurization (RHDS) and vacuum residue desulfurization (VRDS) processes and a method thereof in that a desulfurization waste catalyst produced in the residual hydro desulfurization (RHDS) and vacuum residue desulfurization (VRDS) processes can be organic solvent-cleaned and organic acid-cleaned in one reactor.

Abstract: A spool-out type booster brake valve device for industrial vehicles is configured to allow hydraulic working fluid to be supplied not only to a booster chamber but also to a master chamber thereby eliminating the need to use a separate brake fluid reservoir tank for supplementing brake fluid in the master chamber. The brake valve device is used in an industrial vehicle equipped with a fluid pump, a reservoir tank and a brake actuator. The brake valve device includes a valve body having an inlet port, a drain port, a brake port, a booster chamber communicatable with the pump via the inlet port and a master chamber communicatable with the brake actuator via the brake port. The master chamber is connected to the inlet port to receive working fluid from the pump. A valve spool is slidably fitted in the valve body through the booster chamber and the master chamber, the valve spool being shifted between an idle position and an operating position.
