Multipurpose Technology in Ethanol Production from Cellulosic Feedstocks

May 23rd, 2011

As ethanol production witnesses a complex series of technical and financial problems, commercial firms have started to devise methods robustly for addressing those issues in a compressed way. Chemtex and Gruppo Mossi and Ghisolfi, have invested significant currency and dedication for the development of the PROESA™ ligno-cellulosic bio-ethanol technology. The scientists have engineered and constructed a pilot facility in Rivalta, Italy where they have developed a unique bio-mass pretreatment and hydrolysis process, for which 11 patent applications have been filed, for transforming cellulosic feedstocks into sugars for conversion into ethanol and/or bio-based chemicals. Some of the key features include Capability to use a large variety of biomass as collected, Unique pre-treatment process that produces high quality and low cost sugar from cellulosic biomass for conversion to ethanol and/or bio-based chemicals, High efficiency in viscosity reduction enzymatic hydrolysis and Energy integration with high efficiency burning of lignin. It is really exciting to watch such  a powerful technology with scope to satisfy and improve multiple tasks technically which in turn carry a profound influence in the flow of money for production.

 

Novel Technologies in the Generation of Bioethanol

May 23rd, 2011

Technological advancements are constantly evolving to meet the difficulties and maximize the scope of value added product generation in ethanol production process. Archer Daniels Midland Company makes ethanol from corn through an efficient process that also produces large amounts of animal feed. In addition, they are working both independently and in partnership with other leading companies and research institutions to develop next generation biofuels made from cellulosic sources.

Archer Daniels Midland (ADM) will develop a pilot plant to demonstrate the continuous production of cellulosic ethanol and ethyl acrylate from densified corn stover. Archer Daniels Midland (ADM) developed a process to pretreat and pelletize corn stover, increasing its density for easy transportation and long term storage. At the central plant, the densified corn stover is separated into its three major components: cellulose, hemicellulose, and lignin. Hydrolysis converts cellulose and hemicellulose fractions into sugars, while lignin is utilized as an energy source for process steam generation. Some of the sugars are fermented to ethanol and the remaining sugars hydrogenated to polyols. Catalytic conversion of the polyols, followed by processing of resulting intermediates, yields the chemical, ethyl acrylate. This value-added compound is used to make plastics, adhesives, paints, coatings and a range of other materials. Industrial strategies such as these would make a balance in the cost expenditures for ethanol production and even ensuring additional income.

 

Cost Effective Technology for Alcohol Production

May 23rd, 2011

Globe is now under a tremendous pressure for energy and people currently are exploiting fossilized fuels as their prime source of energy. However it has resulted in some serious consequences including global warming and lack of sustainability which makes human intellectuals to scan for bio based renewable materials as alternative sources for energy production. They are of different categories and ethanol based biofuels is one of the most promising classes because of its feasibility for commercial scale production. The technology has been facing constant problems and sometimes treated inferior to earth fuels on grounds of cost. It prompts research and commercial units to conduct rational scientific research in cutting down the costs.

 

Coskata Inc., a leading developer of biology-based technology for the production of biofuels, launched and unveiled its proprietary process. The process can produce ethanol almost anywhere in the world, using a wide range of feedstock, for less than US $1.00 per gallon, according to the company. This technology makes the widespread use and availability of ethanol much more achievable.  Using patented microorganisms and transformative bioreactor designs, Coskata ethanol is produced via a unique three-step conversion process that turns virtually any carbon-based feedstock, including biomass, municipal solid waste, bagasse and other agricultural waste into ethanol  carbon dioxide emissions by as much as 84% compared to

conventional gasoline. Technologies such as this developed with broad dimension are most sought to promote biofuels.

Gasification Technology Council Urges Congress to Support Gasification

Clean Gasification Technology Critical to Meeting the Nations Energy Needs

Thursday January 29, 2009

Press release

ARLINGTON, Va.– Today, the Gasification Technologies Council (GTC) called on Members of Congress to support the Economic Stimulus and Energy Policy provisions to assure completion of Integrated Gasification Combined Cycle (IGCC) power generation and Industrial Gasification (IG) projects that qualify for tax credits and Federal Loan Guarantees (FLG’s). This will help gasification realize its full potential in creating jobs for American workers and providing an environmentally responsible way to produce power and products from domestic sources.

“Gasification provides the lowest cost solution to produce power, chemicals, fertilizers and fuels from coal, petroleum residues, biomass and wastes while capturing carbon dioxide for sequestration. This way of producing energy provides the path forward for crucial sectors of the economy by using lower cost domestic energy resources,” said James Childress, Executive Director of the GTC. “Congress needs to act now to give the American people the full benefit of this technology. In today’s economic environment, it makes sense to support gasification for both short-term and long-term gains.”

Gasification is an environmentally responsible way to produce power and products from carbon-based materials. Gasification does not involve combustion (or burning), but instead uses intense pressure combined with oxygen and steam to convert carbon-based materials directly into gas. It provides an alternative to natural gas in the manufacture of chemicals, fuels and fertilizer.

In their letter to Members of Congress, GTC specifically asked for:

* A doubling of the Environmental Policy Act of 2005 Sections 48A and 48B investment tax credit (ITC), maximum project caps for all IGCC power generation and industrial gasification projects, and a commitment to a program to commercialize gasification-carbon capture and sequestration (CCS) technologies with ten or twelve commercial scale projects;
* Extensions of “in service” deadlines to accommodate projects that have been delayed by economic and policy driven factors beyond their control;
* An increase in the value of Environmental Policy Act of 2005 Section 45Q CCS production tax credit (PTC) by at least two fold and extension of the PTC availability to all eligible entities through 2019 in order to ensure that new generation and industrial projects can proceed with certainty concerning carbon sequestration; and
* For all projects under development through the FLG process: an increase by $1 Billion in FLG loan volume; coverage of credit subsidy costs; timely regulatory review and process implementation; and extension of credit at reasonable rates to critical independent, but integral, project components (e.g., CCS and air separation).

GTC represents more than seventy-five companies that are playing an important role in revitalizing the American economy, at the same time that they are helping to meet the nation’s energy needs. Members of GTC provide technologies, equipment or services, or own and operate plants that account for more than 95% of gasification capacity around the world. They are also involved in a number of new U.S. projects being planned, designed, or under construction.

Biomass Gasification Tech to Supply Power to Indian IT Parks

February 7th, 2009

In order to supply continuous power to the far-flung IT Parks and Special Economic Zones across the country, AllGreen Energy is setting up biomass-based renewable energy projects in India.

The technology offers several environmental benefits like ‘carbon neutral’ since only the carbon absorbed during photosynthesis is released back into the atmosphere. Secondly, due to the efficient thermo-chemical conversion in the biomass gasification process, there are no particulate emissions into the atmosphere.
