An improved evaporative emission mitigation system for a motor vehicle includes a canister filled with an adsorbent material connected to a membrane module. The membrane module contains a membrane that separates gaseous hydrocarbons from inert air components within fuel vapor generated by the evaporation of fuel due to the heating of the motor vehicle. The gaseous hydrocarbons separated by the membrane are returned to the canister, where they will again be adsorbed by the adsorbent material. The inert air components are vented from the membrane module into the open atmosphere outside of the motor vehicle.

Textured sorbent material sheets provide for enhanced performance in vapor adsorbing applications over conventional sheets, systems, canisters and other emissions control equipment. The textured sorbent material sheets can be formed as part of a small, lightweight system, canister, or can be integrated into a fuel tank.

The present invention concerns a method of decarbonating a gas stream containing from 15% to 60% carbon dioxide, by passage of the said gas stream over a zeolitic agglomerate comprising at least one binder and at at least one zeolite, and having a mesoporous volume of between 0.02 cm.sup.3.Math.g.sup.1 and 0.15 cm.sup.3.Math.g.sup.1 and a mesoporous volume fraction of between 0.1 and 0.5, preferably between 0.15 and 0.45.

A powdery calcium-magnesium compound used as a sorbent composition in flue gas treatment, compatible with electrostatic precipitators. The calcium magnesium compound is doped with calcium nitrate or nitric acid to reduce the electrical resistivity of the particles, increasing their collection efficiency.

A method including adding to or positioning in a vehicle air conditioning system a solid form adsorbent. The solid form adsorbent includes a plurality of discrete adsorbent particles spatially bound in place by point bonding with a binder. At least about 25% of the external surface area of a majority of the particles is not sealed off by the binder and is available for adsorption.

The innovation uses the disparity between dry and wet conditions of the air, by storing the dryness or wetness in a hygroscopic material. When the surrounding air is drier or wetter than the hygroscopic material, the potential energy difference between moisture in the air and that in the material can be used as a way of transporting heat from the material to the air and vice versa. A simple way this energy can be used is for heating and cooling of a building. For example, a large storage of adsorbing material can be dried in the hot summer, and allowed to re-adsorb water in the cold winter, thus gaining heat that can be used for domestic heating.

In some embodiments, there is provided a scrubber system for cleaning return air in an HVAC unit, where the scrubber system attaches directly to an inlet of the return-air side of the HVAC unit, for example, by the mating of a flange on the system with a matching flange on the HVAC unit. The bolt-on scrubber system may comprise one or more sorbent materials, a fan for circulating return air through the sorbent, a damper-controlled inlet and a damper-controlled outlet to the attached return air side of the HVAC unit. Further, an additional air flow channel and a damper may be included in the system to control the flow of outside air into the HVAC unit. In some embodiments, the sorbents may be contained in removable inserts.
