Abstract

The invention discloses a method for hydrogen production by phenol adsorption enhanced reforming. In this method, a fixed-bed reactor is filled with catalytic and CO absorption 2 Functional Ni-Ca-Al-O bifunctional catalyst, in the case of an inert gas as a carrier gas, with a weight hourly space velocity of 0.432-2.592h ‑1 A phenol solution with a concentration of 0.0399-0.1594g / ml is introduced, and the reaction temperature is 400-700°C; when CO 2 After the adsorption is saturated, the catalyst is regenerated at 500-1000°C for 0.1-3h in an inert atmosphere. The hydrogen purity obtained in the invention can reach more than 98%, the conversion rate of phenol can reach more than 99%, and the stability of catalysis and adsorption is good.

Description

technical field

[0001] The invention belongs to the field of energy technology, and in particular relates to a method for hydrogen production by phenol adsorption enhanced reforming. Background technique

[0002] In recent years, with the rapid growth of global energy demand, fossil energy has been consumed sharply, and serious environmental and climate problems have also been caused. Therefore, the research on the conversion of biomass resources into energy and chemical raw materials with the main purpose of finding substitutes for fossil raw materials has attracted the attention of many countries in the world. Hydrogen energy is regarded as the clean energy with the most development potential in the 21st century. Since the 1970s, hydrogen energy research has been widely carried out in many countries and regions in the world. Although most of the raw materials for hydrogen production currently use fossil fuels such as methane, considering environmental protection issues, t...
