A method for enabling gas exchange and chemical reactions with one or more liquid streams contained in a reactive process vessel are provided. One or more exchange layers within the process vessel can be composed of both collector media and releaser media. The exchange layers allow elements to facilitate increased performance of vessel operations by promoting gas component mixing and diffusion. Improved rates of gas component exchange mean less coking and more gas components available for reaction.

Resaturation of gas into a liquid feedstream

A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

Use of treating elements to facilitate flow in vessels

Process vessels can contain one or more entry zones containing stability-improving materials. The entry zones address bed movement and filtration problems. The stability-improving material can be positioned above a treating zone or above a processing bed within the vessel. Entry Zones are intended to improve the stability of downstream operations.

A transesterification catalyst that is heterogeneous and a method for preparing said transesterification catalyst are provided. The catalyst can be used in a variety of transesterification reactor configurations including CSTR (continuous stirred tank reactors), ebullated (or ebullating) beds or any other fluidized bed reactors, and PFR (plug flow, fixed bed reactors). The catalyst can be used for manufacturing commercial grade biodiesel, biolubricants and glycerin.

Structured elements with capabilities for stream flow division and distribution and mitigation of undesired species that exceed those of conventionally available materials are provided. The structured elements provide increased opportunities for surface attraction, retention and coalescence of undesired species in a process stream. The functional contact surfaces of the structured elements can include one or more of the faces of cells, the surfaces of struts connecting cells, the surfaces of nodes connecting struts, and the surfaces of asperities or irregularities caused by channels, flutes, spikes, fibrils or filaments in or on the material surfaces.
