Embodiment 1

[0015] Feed the biomass fast cracking oil and steam into the reactor, the reactor temperature is 600°C, the pressure is 0.15Mpa, the volume flow rate ratio of the biomass fast cracking oil and water is 1:7.8, and a nickel-aluminum catalyst is placed in the reactor , wherein the content of nickel is 10%, the dosage is 40% of the oil intake, and the residence time is 0.07s. After the raw material undergoes a series of complex reactions such as gasification, decomposition, and reformation in the reactor, the gas product obtained is condensed, Collect after drying. During this process, the hydrogen content in the obtained gas product was 34.3%.

Embodiment 2

[0017] Other conditions are identical with example 1, and reaction temperature rises to 800 ℃, and hydrogen content 35.6% in the gaseous product.

Embodiment 3

[0019] Other conditions are identical with example 2, and the volume flow rate ratio of biomass rapid cracking oil and water becomes 1: 14, and the residence time is about 0.03s, and hydrogen content 39.5% in the gaseous product

Abstract

The present invention discloses one process of preparing hydrogen with biomass fast cracking oil. The biomass fast cracking oil as main material and the Ni / Al2O3 catalyst are water vapor catalytically reformed under proper reaction temperature, reaction pressure, reaction time and other technological conditions to prepare synthetic gas with rich hydrogen content. The present invention provides one new way for producing hydrogen and lays foundation for the subsequent processing of biomass cracking oil and the development of biomass resource.

Description

technical field [0001] The invention belongs to a method for producing hydrogen, which uses biomass cracked oil as a raw material, and produces synthesis gas rich in hydrogen through steam catalytic reforming. technical background [0002] Hydrogen energy is an ideal clean energy with good combustion performance, fast ignition, wide flammability range when mixed with air, high ignition point, fast combustion speed and high calorific value. Compared with other fuels, hydrogen is the cleanest when it burns. Except for water and a small amount of hydrogen nitrogen, it will not produce dust, carbon monoxide, carbon dioxide, hydrocarbons, lead compounds and other substances harmful to the environment. A small amount of hydrogen nitrogen is passed through Proper treatment will not pollute the environment, and the generated water can be recycled. Hydrogen can appear in the form of gaseous, liquid and solid metal hydrides, which can adapt to the requirem...
