Hydrogen Production and Biofuel Engineering Lecture 35 Lecture Review

These flashcards cover key concepts related to hydrogen production and its significance in biofuel engineering.

What is the primary chemical property of hydrogen?

It burns with oxygen to form water.

From which Greek words is the name 'hydrogen' derived?

It means 'maker of water'.

What is the dominant method of hydrogen production in the US?

Steam methane reforming (SMR).

What is the main use of hydrogen in the United States?

Petroleum refining.

What is 'green hydrogen'?

Hydrogen produced through electrolysis using renewable energy sources.

What does the 'hydrogen economy' envision?

A future economic system where hydrogen is a central energy carrier, replacing or reducing reliance on fossil fuels.

What is the role of the water-gas shift reaction in hydrogen production?

It removes carbon monoxide and carbon dioxide during hydrogen production.

What is one key biological method for hydrogen production?

Bio-photolysis, where microorganisms use sunlight to split water.

Which technology combines steam reforming and partial oxidation?

Autothermal reforming (ATR).

What are the two methods for hydrogen production from biomass mentioned?

Thermochemical methods (gasification, pyrolysis) and biological methods.
