Converting CO2 into methane is a way to mimic the natural carbon cycle and close the energy cycle by producing synthetic hydrocarbons (see, for example, CO2 Utilization, Chem. Eng., July 2013, pp. 16–19). However, the Sabatier reaction (CO2 + 4H2…
Cellulose nanocrystals New research from Purdue University (West Lafayette, Ind.; www.purdue.edu) has shed some light on the physical properties of cellulose nanocrystals. The nanocrystals, which are about 3-nm wide and 500-nm long, have historically been difficult to analyze, but…
Techniques for manufacturing carbon adsorbent materials with highly tuned pore properties have been developed by EnerG2 Technologies Inc. (Seattle, Wash.; www.energ2.com). The technology platform produces carbon adsorbents that enable the storage of natural gas at significantly lower pressures than those…
Water treatment technology from Alcoa Inc. (Pittsburgh, Pa.; www.alcoa.com) that includes engineered areas of natural wetland vegetation is now available commercially for the first time. The engineered wetlands technology can lower capital and operating expenses, as well as energy consumption,…
Australian researchers have developed a method of cleaning arsenic out of contaminated water by combining the effects of bacteria and microalgae. Professor Megh Mallavarapu and his team, from the Cooperative Research Center for Contamination Assessment and Remediation of the Environment…
A high-throughput method for synthesizing ionic-liquid-containing electrolytes developed by Boulder Ionics Corp. (Arvada, Colo.; www.boulderionics.com) has been refined to enable its use in commercial production. Boulder Ionics had previously piloted the continuous process for producing advanced ionic-liquid (IL) electrolytes at…
Offgases containing compounds of chlorine or fluorine are typically burned to enable the recovery of HCl or HF and prevent release into the environment. However, conventional combustion chambers require a long time to heat up, and thus are typically run…
Extraction of palm oil generates large amounts of lignocellulose-rich byproduct known as empty fruit bunch (EFB), which is usually wasted. A new process for utilizing this waste to make lactic acid has been developed by a team of researchers in…
Professor Takao Masuda and colleagues at Hokkaido University (Sapporo; www.eng.hokudai.ac.jp/labo/cse), in collaboration with Idemitsu Kosan Co. (Idemitsu; Tokyo; both Japan; www.idemitsu.com), have developed a two-step process that converts wood-based lignin into phenols. They believe the achievement could lead to an…
An Australian team has implemented several changes to the conventional organic rankine cycle, resulting in a highly efficient regenerative thermodynamic cycle for producing electricity from waste heat and other thermal sources. The University of Newcastle’s Priority Research Center for Energy…
