    ionic-liquidsIf you talk to winemakers, they will tell you that it is good practice to blend different types of grapes to get that balance in terms of flavors. Maybe a few years from now, this will also be true for biofuels that we will be using for our cars.

    A study conducted by Joint BioEnergy Institute in collaboration with the Department Energy of the United States established that ionic liquids can be used to pre-treat individual or blend of feedstocks of biofuels.

    The experiment yielded promising results, showing the ionic liquids can effectively handle milled feedstocks that have been turned into pellets. After treatment, the biofuel feedstocks can still yield a good amount of fermentable sugars. This only shows that blending and even densifying a variety of feedstocks has a good potential to make a biofuel technology for the transportation sector cost-competitive.

    The proponents used a good variety of plants that can serve as fuel crops. The materials were mixed and then milled to pellets or floor then pretreated with an ionic liquid. The experiment aimed at determining the effect of mixing the feedstocks and densification of the blend on the biomass that yields fermentable sugars for production of biofuels.

    The team is investigating methodsto up the energy densities of the biomass feedstocks in order to make delivery to transportation biofuel refineries more economical. The results of the experiment proves that biofuel feedstocks can be densified into pellets or flours without significant effects on their sugar yield.

    The proponents used blends of lodgepole pine, eucalyptus, corn stover, and switchgrass to make pellets and flour then processed it within a day. The material still yielded about 90% in either forms upon saccharification.

    The next step of the study will be to determine the most cost efficient blend of feedstock in pellet form in the United States and then determine the most efficient process to convert them to biofuels.

    Special chemical firm Evonik introduces the bio-derived variant of MTBE or methyl-tertiary-butyl. The MTBE is an oxygenate that helps improve the combustion of gasoline, prevent knocking of the engine, and lower carbon monoxide and other harmful emissions. It is made from biomethanol and isobutene in their Marl, Germany factory.

    The MTBE has been known for decades as an antiknocking agent , the Bio-MTBE also has the same technical properties in terms of energy density, oxygen content, solubility, and vapor pressure as its conventional counterpart. This means that the Bio-MTBE can be sent through pipelines, stored in tanks, and handled in the refineries safely.

    Since it is formulated from the raw form of glycerine, a co-product when manufacturing biodiesel, bio-methanol is considered as a waste product in the EU. This fact makes Bio-MTBE a viable option for manufacturers that hope to meet the specs of the EU for using biofuels

    Evonik has the Netherlands and Germany as its primary markets for the Bio-MTBE and the implementation of the EU directives in other member countries shows the good potential for the product. European specs for gasoline allows 15% of MTBE while the revised directives for fuel quality expanded this to 22% for gasoline.

    In the United States, MTBE has been used since 1979 in place of lead to boost the octane level of the fuel. Starting in 1992, MTBE has been used in higher concentrations in accordance with the clean air act enacted in 1990. In the late 90s though, some drinking water samples tested positive for MTBE so a lot of states started to phase it out.

    biofuelPushed by the need to address concerns with regard to climate change, economics, and energy security, more than 30 governments across the globe have enacted laws to facilitate the faster production of biofuels and expansion of their infrastructure. The better production of biofuel will somehow lessen the use of fossil fuels especially by the transportation industry.

    According to a recent research, the biofuel industry will double its market value due to increased production and consumption in a decade’s time. Experts foresee it to grow from $82.7 billion this year to around $185 billion come 2021.

    The widespread growth of the industry across regions will reshape industries and the geopolitical landscape according to analysts. Steps must also be taken to overcome challenges to meet the possible high demand of the ground, maritime, and aviation fuel markets.

    Although the fuel industry have shown considerable success in the United States, European Union, and Brazil, the issue to face now will be sustainability, product neutrality, and feedstock versatility. The   experts agree that the use and production of biofuels will be spreading to developing and developed economies in the next ten years but the access to feedstock will lead to big trades across country with Brazil being the key supplier.

    The projections were made by Pike Research thru their report called Biofuels Markets and Technologies detailing key opportunities and challenges in biodiesel and ethanol. They looked into developments of policies, market drivers, feedstock economics, production, demands in different sectors, and the major industry players.
