METHOD AND MATERIALS FOR STORING HYDROGEN

摘要

FIELD: chemical engineering. ^ SUBSTANCE: catalytic composition material comprises a mixture composed of acetylene hydrocarbon with aromatic substituent or potential oligomer that represent a hydrogen source and carrier and metal of VIII group that represents a heterogeneous catalyzer. The mass ratio of the hydrogen source and catalyzer ranges from 5:1 to 1000:1. The method comprises filling the system with hydrogen in the course of the contacting of acetylene hydrocarbon with the heterogeneous catalyzer in heated tank at a temperature of 50-200°C and hydrogen pressure of 5-1 atm and extracting hydrogen from the system when completely hydrated hydrocarbon in the first stage is in a contact with the same catalyzer at a temperature 200-350°C and pressure 0.5-5 atm. ^ EFFECT: increased rate of extracting. ^ 10 cl, 2 dwg, 2 tbl, 8 ex
