A sorption-enhanced catalyst improves CO2 methanation
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…
February Chementator Briefs
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…
Optimized carbon-adsorbent material for natural gas storage
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…
Engineered wetlands technology now available for wastewater treatment
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,…
A self-cleaning electrolytic cell that converts waste streams into disinfectants
Dealing with wastewater streams in petroleum refineries and petrochemical operations is often a trying task — environmentally, economically and logistically — especially as regulations on salinity in waste streams are tightened. However, many waste streams actually contain useful components, such…
Selectively recover CO with this soft nano-porous material
Professor Susumu Kitagawa’s group at Kyoto University (Kyoto, www.sbchem.kyoto-u.ac.jp/kitagawa-lab/index-e.html) has developed a new soft nanoporous material that selectively adsorbs carbon monoxide from gas mixtures. The researchers believe their achievement will enable the separation and recycling of CO from the emissions…
Making liquid fuels from waste plastics
Gasoline-like fuel suitable for internal combustion engines can be obtained from the pyrolysis of plastic waste, according to a study conducted by a team of people from Gadjah Mada University (Yogyakarta, Indonesia; www.ugm.ac.id), University Sains Malaysia (Penang, Malaysia; www.usm.my), and…
Continuous crude-oil production from algae
Scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed a continuous process for generating crude oil from algae that they believe can lower the cost of producing algae-based fuel. The process works by combining hydrothermal liquefaction and…
Advanced battery electrolytes made with low-cost, high-throughput method
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…
This graphite burner enables on-demand treatment of offgases
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…
