Conversion of carbon dioxide to methanol

Rahman G., Chung Y.H., Hallym University, KR

Carbon dioxide has been converted to methanol by means of electrochemical reduction using electrodes of metal oxides. The electrodes used in the conversion of CO2 consisted of Ru/Ir/Co oxides in the atomic ratios of Ru/Ir/Co [...]

Cleaning the Engine Exhaust without Precious Metal Catalysts

Gokturk H., Ecoken, US

Internal combustion engine which serves as the main driver of modern transportation emits a number of pollutants which include carbon monoxide, nitrogen oxides, hydrocarbons and micrometer size particulates. Carbon dioxide (CO2), which is not a [...]

Status of CO2 Capture Technologies

Bhown A.S., Electric Power Research Institute, US

EPRI has an on-going effort to understand the landscape of postcombustion CO2 capture technologies globally, and accelerate their development. Several central issues facing CO2 capture involving scale, energy, and overall status of development will be [...]

A high temperature, lithium orthosilicate based solid absorbent for post combustion CO2 capture

Quinn R., Air Products and Chemicals, Inc., US

Capture of carbon dioxide from combustion processes presents a unique and challenging technical problem arising from low CO2 partial pressures, high flow rates, and the presence of water vapor and reactive contaminants such as SO2. [...]

Bio-oil blend: next generation heating oil

Hemeyari R., Mohapatra S., Manesh A., American Science and Technology Corporation, US

Pyrolysis experiments are carried out in Auger pyrolysis unit located in AST. Bio-oil produced in our pilot plant are blended with commercial heating oil and/or with biodiesel. Biodiesel are available by AST’s 1mGal/yr biodiesel pilot [...]

The New OPEC

Pfaltzgraff L., Budarin V., Clark J.H., Green Chemistry Centre of Excellence, UK

Society faces the twin challenges of resource depletion and waste accumulation, increasing concerns to governments leading to increasing taxes for waste disposal restrictive legislation. Research in the area of renewable feedstock is of great importance [...]

Starbons® – A New Family of Bio-based Mesoporous Materials Derived from Polysaccharides

Clark J.H., Budarin V.L., Breeden S.W., Green Chemistry Centre of Excellence, UK

Starches from a wide variety of sources and locations can be physically expanded giving high surface areas and mesoporosity. Heating these materials leads to a family of “Starbons” with tunable surface properties depending upon activation [...]

Integrated Photocatalytic and Microbial Degradation of Kraft Lignin

Shende A., Shende R.V., Hussein M., Bhosale R., Harder-Heinz D., Shende A., Shende R.V., South Dakota School of Mines & Technology, US

Kraft lignin (KL), a waste product of paper and pulp industry is recalcitrant to biochemical degradation. In our attempt to overcome KL recalcitrance, we coupled photoreforming of Kraft lignin (KL) with microbial degradation. It is [...]

Development of One-Step Jet Fuel Blend using Solid Acid Catalysts

Mohapatra S., Hemeyari R., Manesh A., Misra M., American Science and Technology Corporation, US

In this work we will discuss the conversion of various feedstocks such as vegetable oil/algae oil/coffee oil/crude biodiesel to JP8 fuel using solid acid and bi-functional catalysts. The developed catalyst performs deoxygenation, cracking and isomerization [...]

Clean Production of Bioplastic and Bio-oil from Solar Energy and Carbon Dioxide

Yu J., University of Hawaii at Manoa, US

Producing fuels and materials from solar energy and CO2 is a clean sustainable solution to the arising fossil energy consumption and CO2 emission. This paper presents a high intensity process that can run continuously at [...]
