Ethanol from CO2

Scientists at the U.S. DOE’s Oak Ridge National Laboratory (ORNL; Tenn.; www.ornl.gov) have developed an electrochemical process that directly produces ethanol from CO2. The researchers used a catalyst consisting of copper nanoparticles embedded in carbon spikes, and applied voltage to…

Commercial MOFs on the horizon

A partnership between materials company NuMat Technologies (Skokie, Ill.; www.numat-tech.com) and The Linde Group (Munich, Germany; www.the-linde-group.com) is set to bring metal-organic-framework (MOF) materials into the mainstream industrial-gas sector. Touted for their extremely high surface area and adsorption capacity, MOFs…

Plasma oxidation disinfects water without the addition of chemicals

A new technology that uses plasma to kill bacteria and simultaneously oxidize organic material in water systems offers a non-chemical alternative to water treatment in several industry sectors, such as food and beverage, power generation, oil and gas and others.…

Tin-based catalyst for photodecomposition

Daylight-driven photocatalysts have attracted much attention in the context of “green” technology for reducing pollutants. Although a number of active materials have been reported and their applications are rapidly increasing, many are discovered after enormous experimental efforts. Now, Isao Tanaka…

A Japanese consortium begins a five-year, large-scale carbon-capture project

Toshiba Corp. (www.toshiba.co.jp), Mizuho Information & Research Institute, Inc. (MHIR; both Tokyo, Japan; www.mizuho-ir.co.jp) and 11 other industrial and academic partners have been selected to carry out a five-year project, “Demonstration of Sustainable CCS Technology Project,” sponsored by Japan’s Ministry…

This ceramic membrane converts natural gas to liquid hydrocarbons

Converting natural gas to liquid hydrocarbons can theoretically be accomplished at high temperatures with the help of zeolite catalysts, but the reaction is hindered by two major factors. The conversion to products is thermodynamically limited, and coke formation on the…

Purify p-xylene without the heat

Current commercial technologies for separating and purifying p-xylene — an important precursor for polyesters and plastics — from hydrocarbon mixtures involve phase-change techniques that require large amounts of thermal energy. Recently, a research team from Georgia Institute of Technology (Ga.…

Catalytic process converts sorted waste into aromatic compounds

The rising cost of landfilling trash creates a strong incentive to utilize the waste for saleable products. A recently piloted process is an example: the process can convert municipal solid waste (MSW) into a narrow range of valuable aromatic compounds.…
