A fuel tank for storing a hydrogen liquid carrier and a spent hydrogen liquid carrier includes a substantially rigid exterior tank wall including a first chamber and a second chamber. The first chamber is fluidly disconnected from the second chamber, and the second chamber includes a dynamically expandable and contractible enclosure, the enclosure being configured to define a dynamic boundary between the hydrogen liquid carrier and spent hydrogen liquid carrier. The fuel tank also includes a first channel in flow communication with one of the first chamber or the second chamber and a second channel in flow communication with another of the first chamber or the second chamber, wherein the first channel and the second channel are flow connected such that a flow through one of the first or second channels is returned to the another of the first or second channels, and that during the flow, the dynamic boundary changes position causing a change in a volume of the second chamber.

A feed gas feeding system for a propylene ammoxidation reactor comprises a feed gas mixing system and a feed distributor, wherein a propylene and ammonia mixed gas is mixed by the feed gas mixing system and then uniformly distributed in the propylene ammoxidation reactor by the feed distributor. The initial temperature T.sub.0 when the propylene and ammonia mixed gas enters the feed distributor is 10-220° C. The feed gas feeding system can prevent the temperature of the gas mixture at any position in the feed distributor from reaching a temperature at which ammonia decomposes into active nitrogen atoms, thereby reducing a risk of brittle nitriding fractures of the feed distributor.

The present disclosure relates to a continuous flow process for preparing conducting polymers, for example polyaniline. The continuous flow process can provide a controlled synthesis of a conducting polymer from an emulsion comprising a polymerizable organic monomer and a free radical initiator in flow within a temperature controlled continuous flow reactor comprising at least one mixing element. The present disclosure also relates to the conducting polymers prepared by the continuous flow process.

The present invention discloses a systematic method for phosphorus sustainability, sand soilization and odor removal utilizing the phosphorus-unlocking and odor removing green chemistry of a surface-oxygenated biochar composition made through ozonization in combination with sonication. Surface-oxygenated biochar compositions and sonication-ozonization methods create advanced hydrophilic biochar materials having higher cation exchange capacity, optimized pH, improved wettability, and toxin free components. These sonicated and ozonized biochar compositions are used as filtration materials for clean water and air, as phosphorus solubilizing reagents to mix with phosphate rock materials to make a slow-releasing phosphate fertilizer, as biochar soil additives to help solubilize phosphorus and reduce phosphorus fertilizer additions required to achieve desired soil phosphorus activity, crop uptake, and yield goals, as sand soilization reagents by utilizing their liquid gel-forming activity in the spaces among sand particles to retain water and nutrients and hold the sand particles together, as plant growth stimulants by using the humic acids-like surface-oxygenated biochar substances at a proper ppm concentration and as carbon sequestration agents to help control climate change for energy and environmental sustainability on Earth.
