Disclosed herein is a method for making hydrogen with carbon sequestration. The method may comprise using a biomass hydroconverter product to fuel a steam reformer that converts a hydrocarbon fuel stream into a gas mixture that contains at least hydrogen and carbon dioxide. The gas stream is separated to form a hydrogen-enriched gas stream and at least one hydrogen-depleted stream. The hydrogen-depleted stream may be stored or further processed to sequester the carbon contained therein. Additionally, or alternatively, the solid residue from the biomass hydroconverter also may be stored for further sequester carbon generated by the method.

A separation and purification coupled process with a high helium yield and diversified products is provided. The process is as follows. Firstly, a low-concentration helium-containing gas after being pressurized and pre-treated enters a two-stage and two-section membrane separation unit to produce a helium product with a medium concentration by concentrating stage by stage through the membrane separation unit. A part of the helium with medium concentration enters an adsorption unit for further concentration to produce a helium product above grade A.

Porous solid amine adsorbents are prepared by bringing into contact a first (e.g., dope) solution, including a water insoluble polymer and a water-soluble amine polymer, with an aqueous solution containing a multifunctional chemical agent. The first solution can be obtained by dissolving the water insoluble polymer and the water-soluble amine polymer in a polar solvent. The adsorbents can be in the form of beads, sheets, fibers, hollow fibers, etc. and can be used in the removal of acid gases, CO.sub.2, for instance, from fluid streams.
