New path to low-cost, renewable plastic bottles

New path to low-cost, renewable plastic bottles

May 1, 2012 |

In Massachusetts, a  team of chemical engineers led by Paul J. Dauenhauer of the University of Massachusetts Amherst has discovered a new, high-yield method of producing p-xylene, the key ingredient used to make plastic bottles from biomass. The process is inexpensive and currently creates the chemical  with an efficient yield of 75-percent, using most of […]

Advances with ZSM-5 catalysts could transform pyrolysis biofuels

Advances with ZSM-5 catalysts could transform pyrolysis biofuels

February 7, 2012 |

In Germany and the US, researchers have independently discovered that using a zeolite known as ZSM-5 impregnated with metal nanoparticles can reduce the catalysts needed to transform bio-oil into useful hydrocarbons to just one. Johannes Lercher at the Technical University of Munich in Germany used nickel nanoparticles, while George Huber from the University of Massachusetts-Amherst […]

New catalyst for algal biodiesel produces higher-grade fuels

New catalyst for algal biodiesel produces higher-grade fuels

January 12, 2012 |

In Germany, researchers at the Technical University of Munich have developed a new way to produce biodiesel from microalgae using a novel catalyst based on nickel on a porous support made of zeolite HBeta that produces saturated hydrocarbons suitable for use as high-grade fuels in vehicles. That’s opposed to many algae-based biodiesels that has too […]
