Abstract: In one aspect, the disclosure relates to catalytic phase transfer sorbents (PTS) for producing hydrogen-enriched syngas from a carbonaceous feedstock, the PTS comprising a formula selected from ABO3 and An+1BnO3n+1, wherein A comprises one or more alkali metals or alkaline earth metals, wherein B comprises one or more transition metals, and wherein X comprises an anion. Also disclosed is a system for hydrogen generation from carbonaceous feedstocks, the system comprising a gasifier unit for production of H2-rich syngas and a regenerator unit for regeneration of spent PTS. Further disclosed herein is a method for hydrogen generation from carbonaceous feedstocks using the disclosed systems. The disclosed systems can be operated isothermally through 10 or more cycles without degradation in performance, while the disclosed methods can yield 50% or more H2 relative to carbon-containing species. In some aspects, the methods produce little to no CO2.

Abstract: A lubricator assembly for servicing a tubular member includes a mounting base, a lubricant housing movably coupled to the mounting base and configured to receive lubricant from a lubricant source, a guide pin slidably disposed in the lubricant housing, a first seal positioned between the guide pin and the lubricant housing and a second seal positioned between the guide pin and the lubricant housing, and a first chamber extending between the first seal and the second seal, wherein the guide pin is configured to direct lubricant disposed in the first chamber against the tubular member in response to the tubular member engaging the guide pin.

Abstract: A pallet lifting rack includes a pair of lifting devices. Each of the lifting devices has a frame, a movable bracket mounted on the frame and movable in a vertical direction relative to the frame, a support member connected to the movable bracket, and a driving device driving the movable bracket and the support member to move along the vertical direction. The support members of the pair of lifting devices support a bottom surface of a pallet from a pair of sides of the pallet, so that the pallet is supported on the support members and movable to different height positions in the vertical direction by the support members.
