New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. The approach enables the design of compositionally diverse confined oxide particles with superior stability and catalytic reactivity. Dragos Neagu, Evangelos I. Papaioannou, Wan K.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Earlier post.)

Univ. of Exeter team engineers unique biological pathway for the production of diesel range hydrocarbons by E. coli

Green Car Congress

coli bacteria to produce “petroleum-replica” hydrocarbons in the diesel range. The results presented in this article, although at a very early stage in product development, contribute toward the goals of advanced biofuels by providing metabolic pathways for the production of industrially relevant, petroleum-replica fuel molecules.

JBEI scientists identify new biosynthetic alternative to diesel and engineer microbes to produce its precursor

Green Car Congress

Bisabolane (2); Hexadecane (3), a representative molecule for diesel; farnesane (4); and methyl palmiate (5), a representative molecule for fatty acid methyl esters. One of the avenues being explored is sesquiterpenes, terpene compounds that contain 15 carbon atoms (diesel fuel typically contains 10 to 24 carbon atoms). Earlier post.)

Researcher Says Biodiesel from Sewage Sludge Nearly Cost-Competitive with Petroleum Diesel

Green Car Congress

Existing technology can produce biodiesel fuel from municipal sewage sludge that is within a few cents a gallon of being competitive with conventional diesel refined from petroleum, according to Dr. David Kargbo, with the US EPA’s Office of Innovation, Environmental Assessment & Innovation Division in Philadelphia, PA. per gallon.
