First Generation Biofuels

First generation biofuels are those made from sugar, starch, or vegetable oil.  Their feedstocks are those that may not be sustainable or might have an impact on food if used in large quantities.  These original first generation biofuels include biodiesel, ethanol, green diesel, bioethers, biogas, and the solid biofuels covering everything from wood and sawdust…

Third Generation Biofuels

Third-generation biofuels are currently those related to algal biomass or linked to utilization of CO2 as feedstock.  Unlike first-generation biofuels which were virtually all related to editable biomass, or second-generation biofuels produced from a wide array of different feedstocks, ranging from lignocellulosic feedstocks to municipal solid wastes, these third-generation biofuels are less developed but offer…

Second Generation Biofuels

Second-generation biofuels (advanced biofuels), are those biofuels that can be manufactured from various types of non-food biomass. Examples of second generation biofuels are those made from algae, renewable fuels made via the Fischer-Tropsch process, cellulosic ethanol, and bio hydrogen.  Different from the first generation biofuels, made from edible feedstocks like ethanol from sugarcane or corn,…

Catalyst testing: Lab and Pilot Scale

Energy and chemical technologies heavily rely on solid materials used as catalysts and sorbents for numerous types of chemical reactions and separations. Although significant advances have been made in molecular simulations and modeling for rational design of these solid materials, most newly developed industrial processes still depend on applied methods of testing solid catalysts/sorbents for…

Biomass Supply Chain Expert – Agriculture

What is an agricultural biomass supply chain expert? Simply put, it is a person that understands the dozens of issues that will affect the production of the tens of thousands of tons of feedstock that a project needs to be profitable as it produces a fuel or chemical.  The expert should know how to get…

Renewable Chemicals

Renewable chemicals are slowly replacing fossil-derived chemicals.  These chemicals are often made from renewable resources such as wood, algae, and agricultural waste and can often be one-for-one, identical replacement materials, or in some cases, they are new and improved versions of the chemicals they replace. Ethyl alcohol (ethanol, grain alcohol, drinking alcohol) has been produced…

Techno-economic analysis: Algae Cultivation

How do algae experts assist in techno-economic analysis (TEA).  TEA is the combination of conceptual process design and production cost estimation activities. Algae cultivation refers to the growth and recovery of algal biomass in open ponds or photobioreactors. Many algae strains of interest produce oils that may be used as food or nutraceuticals, or upgraded…

First Generation and Second Generation Biofuels

First generation biofuels are those made from sugar, starch, or vegetable oil.  Their feedstocks are those that may not be sustainable or might have an impact on food if used in large quantities.  These original first generation biofuels include biodiesel, ethanol, green diesel and biogas.  Second generation biofuels are those made from sustainable feedstocks as…
