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

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…
