Optimal Process Design of Hydrothermal SNG Production from Waste Biomass

Abstract

Hydrothermal gasification of biomass in supercritical water is one of the rare pathways that potentially allows for a complete conversion of wet waste biomass into Synthetic Natural Gas (SNG). This paper summarises an extensive process design study and discusses some key aspects of the process integration and, in particular, the influence of the feedstock on the optimal process design and its performances. It thereby demonstrates that the process design and performance is not only influenced by available technology, catalyst deactivation issues and scale, but also the characteristics of the processed substrate.

Biomass (energy)

Biomass, in the context of energy production, is matter from recently living (but now dead) organisms which is used for bioenergy production. Examples include wood, wood residues, energy crops, agricultural residues including straw, and organic waste from industry and households. Wood and wood residues is the largest biomass energy source today. Wood can be used as a fuel directly or processed into pellet fuel or other forms of fuels. Other plants can also be used as fuel, for instance maize, switchgrass, miscanthus and bamboo.

Second-generation biofuels

Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass in this context means plant materials and animal waste used especially as a source of fuel. First-generation biofuels are made from sugar-starch feedstocks (e.g., sugarcane and corn) and edible oil feedstocks (e.g., rapeseed and soybean oil), which are generally converted into bioethanol and biodiesel, respectively.

Biomass

Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g. only from plants, or from plants and algae, or from plants and animals. The vast majority of biomass used for bioenergy does come from plants. Bioenergy is a type of renewable energy with potential to assist with climate change mitigation.
