A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

Popular Abstract in Swedish Akrylfibrer, SAN-plast (Styren-AkrylNitril) och ABS-plast (Akrylnitril-Butadien-Styren) är tre viktiga polymerer som tex används för textilier (akrylfibrer) och optiska instrument (SAN). ABS-plast har hög motståndskraft mot kemikalier samt är slagtålig och används tex i bilar. Gemensamt för dessa tre polymerer är att akrylnitril används som monomer. Akrylnitril tillverkPropane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0.92V0.92O4 was determined by thermogravimetry, X-ray microanalysis, X-ray powder diffraction, and neutron powder diffraction. Sb0.92V0.92O4 was found to have a defective rutile structure involving catio

The impact of price reductions on on individuals’ choice of healthy meals away from home

Food high in energy but low in nutritional value is an important contributor to several serious illnesses, and one type of food that is particularly high in energy but low in nutrition is food consumed away from home. In this paper, we examine the demand and willingness to pay for healthy, Keyhole-labelled meals. A Keyhole-labelled meal is particularly low in calories, fat, sugar and salt, but par
