A zearalenone functionalized graphene surface molecularly imprinted material, a preparation method therefor and the use thereof, which belong to the technical field of molecularly imprinted materials. The zearalenone functionalized graphene surface molecularly imprinted material is prepared by using RGO as a carrier, CDHB as a template molecule, 1-ALPP as a functional monomer, TRIM as a cross-linking agent, AIBN as an initiator, and acetonitrile as a pore-forming agent.

The present disclosure provides an automatic separation apparatus for four fractions of heavy oil and a separation method thereof, wherein the apparatus includes a solvent reservoir tank (1), a separation unit for four fractions of heavy oil (100) and a receiving apparatus (9). The separation unit for four fractions of heavy oil (100) includes: a filter disc (4) having one end in communication with the solvent reservoir tank (1), and the other end in communication with an inlet of a pre-column flow path switching valve (5); a chromatographic column (6) having an inlet in communication with an outlet of the pre-column flow path switching valve (5), and an outlet in communication with an inlet of a post-column flow path switching valve (8). The receiving apparatus is in communication with an outlet of the post-column flow path switching valve (8).

The present disclosure provides chromatography columns and methods of chromatographic separation using the same. In particular, the disclosure provides modified columns where the cross-sectional area of the column increases in an area near the end of the column in a flared manner. The modified columns can be used in Expanded Bed Absorption (EBA) systems.

Embodiments of the hybrid thermal-chromatograph systems described herein solve the co-product generation problem associated with seawater desalination, and result in significant reduction in the selling price of fresh water generated through the process, while also solving problems associated with traditional lithium mining practices.

A device and method for in-line homogenizing a non-uniform feed stream is described herein, which includes a plug flow reactor (PFR), a bypass line, and a pump in a closed-circuit flow path that allows for rapid homogenization of the non-uniform feed stream.

The present invention relates to a method for separating one or more components from a liquid feed mixture in an EBA-SMB operating mode without the need of pumps at the outlets of the EBA columns. The present invention also relates to a simulated moving bed separation device with expanded bed adsorption columns which can be used in the method according to the invention.

A valve block includes a fluid-transfer plate with multiple inlet bores connecting to a common inlet channel, and multiple outlet bores connecting to a common outlet channel. The inlet bores and the outlet bores are arranged in a curved shape. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores.

A chromatography column for the use of separation of acidic sugar chains, wherein the column comprises a first column and a second column, the second column connected by a flow path downstream of an outlet of the first column, and selected from the following (1) or (2): (1) the carrier of the first column is hydrophobically modified silica having a group containing a primary amine, a secondary amine or/and a tertiary amine, and the carrier of the second column is a resin having a group containing a primary amine, a secondary amine or/and a tertiary amine; (2) the carrier of the first column is a resin having a group containing a primary amine, a secondary amine or/and a tertiary amine, and the carrier of the second column is hydrophobically modified silica having a group containing a primary amine, a secondary amine, or/and a tertiary amine.
