Disclosed is an apparatus for separating amine gas from mixed gas, the apparatus including: a washer column through which mixed the gas passes; and a main adsorber column through which the mixed gas passing through the washer column passes. According to the present invention, the apparatus can remove amine gas more effectively and increase the lifetime of an adsorbent by allowing the mixed gas including the amine gas to pass through the washer column and the adsorber column.

Disclosed is a desulfurizer of a fuel cell. The desulfurizer includes a pipe extended long and having one side that is open and the other side that is closed; a cap coupled to one side of the pipe and closing the pipe; a plurality of baffles installed in an inner space of the pipe and sequentially partitioning the inner space in a direction crossing a length direction of the pipe; an inflow pipe penetrating through the cap and the plurality of baffles and communicating from the outside of the pipe to the inner space of the pipe; and an outflow pipe installed in the cap and communicating the outside of the pipe and the inner space of the pipe.

The Phipps indoor air filter (PIAF) is configured for use with an indoor atmosphere that contains one or more pathogenic viruses. The PIAF is a pharmacologically and phytochemically (P&P) active structure that removes the one or more viruses from the confined indoor atmosphere. The PIAF removes the one or more viruses by: a) sequestering the one or more viruses within the PIAF; and, b) terminating the biological processes of the one or more viruses using P&P structures. The PIAF incorporates a flow chamber and a filter structure. The flow chamber contains the filter structure. The flow chamber forces or draws an air flow through the filter structure contained within the flow chamber. The filter structure physically and biochemically: a) sequesters the one or more viruses; and, b) terminates the biological processes of the one or more viruses by exposing the one or more viruses to the P&P structures.

A passive CO.sub.2 collection device is disclosed, including a release chamber and a capture structure having at least three straps and a plurality of sorbent disks coupled to and spaced along the straps. The capture structure is movable between collection and release configurations. Each strap has a primary and secondary width, the secondary width smaller than the primary. The collection configuration includes the disks suspended from a movable portion by the straps such that, for each pair of neighboring disks and for each strap, a lower disk is separated from an upper disk by a connecting segment, allowing the sorbent to capture carbon dioxide from an airflow. The release configuration includes the disks being stacked within the chamber for regeneration. Each connecting segment is in a release topology designed to accommodate stacking the disks within the chamber. The connecting segment is biased to move toward the release topology.

The present invention relates to a pre-hydrotreatment and purification method for waste lubricating oil, the method comprising the following steps: mechanical impurities are removed from waste lubricating oil, and then the oil is subjected to flash distillation to separate free water and a portion of light hydrocarbons; a bottom product of the flash distillation column is mixed with hydrogen and a self-sulfurizing oil-soluble transition metal catalyst, and then enters a slurry bed reactor for pre-hydrotreatment; a gas product obtained by performing separation on a reaction effluent is subjected to adsorption purification and then enters a hydrogen recycle compressor for cyclic use; a liquid product obtained by performing separation on a reaction effluent is subjected to hydrocyclone separation and solvent washing to remove solid residue, and finally a purified lubricating oil component is obtained. The method of the present invention has such advantages as simple processing procedures, a high non-ideal component conversion rate, a high oil liquid yield, and good quality. In addition, the oil-soluble catalyst features simple dispersion, no need for vulcanization, a small catalyst adding amount, high low-temperature hydrogenation activity, and is capable of effectively preventing the coking that could occur during a process of preheating the waste lubricating oil, markedly extending the operational lifespan of a waste lubricating oil hydrogen treatment device.

Systems and methods of separating components of a multi-component gas mixture are described herein. The systems include one or more packed bed columns packed with a biosorbent material. Upon passing the multi-component gas mixture through the packed bed column, substantially all of a polar component of the multi-component gas mixture is adsorbed by the biosorbent material and a non-polar component of the multi-component gas mixture is not substantially adsorbed by the biosorbent material.
