A group at Texas A&M University (College Station, Tex.; www.tamu.edu) is developing a process that converts organic municipal solid waste (MSW) into straight-chain alkanes, a primary component in gasoline. The four-step process (diagram) begins with a proven industrial waste-sorting method (using vibration, magnetism and air currents) that isolates the organic, digestible portion (typically food...

Before the end of 2016, Neste Oil Oyj’s (Espoo, Finland; www.nesteoil.com) refinery in Rotterdam, the Netherlands will start producing 30,000–40,000 ton/yr of biopropane. The feedstock is a sidestream from the company’s 800,000-ton/yr renewable diesel-fuel plant. The refinery, which started up in 2011, makes renewable diesel fuel from vegetable oils and residue fats using Neste...

A high-temperature pressure-swing-absorption (HT-PSA) process that reduces energy consumption by up to 50% compared to conventional PSA technology is being developed by Tokyo Gas Co. (Tokyo, Japan; www.tokyo-gas.co.jp), with support from the New Energy and Industrial Technology Development Organization (NEDO). The HT-PSA process uses a perovskite-type oxide absorbent. Oxygen is separated from pressurized...

A method for using liquid CO2, rather than water, as a hydraulic fracturing fluid has been field-tested in a mid-continent oil well, and has benefited well productivity, according to developer Praxair Inc. (Danbury, Conn.; www.praxair.com). Aside from enhanced well performance, the technology is designed to relieve pressure on freshwater supplies in drought-affected areas. The patent-pending DryFrac...

  Graphene continues to show new, promising properties Researchers from Monash University (Melbourne, Australia; www.monash.edu.au) have discovered that graphene oxide sheets can change their structure and become liquid droplets spontaneously. Because graphene droplets change their structure in response to an applied magnetic field, they could be used for controlled drug release, says lead researcher...
