Renewable green diesel-type alkanes can be produced by hydrotreating jatropha oil and vegetable oils at standard conditions (i.e., 543−573 K) with Pt/H-ZSM-5 catalysts, which are active under the weight ratio of or oil/catalyst 1. The carbon molar yield straight chain C15−C18 was ∼80% for pure oil. However, 10, being important from a practical point view, falls to only 2.3%. Under high rhenium-modified catalyst is found effective raising yield. 67% an optimun Re/Al 0.8. Investigation natures...
A pressurized rotary reactor was used to produce hydrogen and solid carbon through thermochemical decomposition of methane using an Fe catalyst. Here, the ratio (CH4 flow rate)/pressure kept constant. Pressurized conditions caused a lower initial conversion, but decrease in conversion over time suppressed, ultimately higher than that at ambient pressure after long reaction time. The deposited formed as nanofibers nano-onions. At pressure, crystallinity also slightly increased. Unreacted...
Ethanol conversion to C3+ olefins over Fe/H-ZSM-5 catalysts was investigated. Fe is a non-toxic and cheap metal. are useful not only as fuels but also chemicals. fully effective even in the presence of water EtOH. Therefore, there no need remove from water-containing ethanol, such bio-ethanol. The initial selectivity affected by kind source calcination temperature significantly, except case iron phosphate used source, which showed low selectivity. In general, slightly decreased with...
Hydrogen production by cellulose gasification over Ni catalysts was investigated. The catalytic activity and the species of products were affected type supports. use simple metal oxides as supports resulted in formation large quantities dark-colored tar but avoided carbon deposition, whereas zeolites inhibited promoted deposition. loading Ce on zeolite enhanced rate partially On other hand, most cases, higher reaction temperatures led to a greater quantity hydrogen being formed,...
Renewable green aviation and diesel-type alkanes can be produced by hydrocracking of Botryococcus braunii oil (Bot-oil) squalane oils with Pt–Re/SiO2–Al2O3 (SA) catalysts, which are active at 310–340 °C the weight ratio oil/catalyst 10. For purified Bot-oil on Pt–3 wt % Re/SA 330 °C, highest fuel-range hydrocarbon (C10–C15) yield 50.2% was achieved, diesel-range hydrocarbons (C16–C20) 16.7% yield. The re-modified Pt/SA catalysts also for as model compound algae oil, C10–C20 68.8% obtained....
Various H-ZSM-5 catalysts were assessed for ethanol conversion into lower olefins. Ethanol was converted to olefins over catalyst without modification. The selectivities ethylene and propylene much than those aromatics such as benzene, toluene, xylene (BTX), C1-C4 saturated hydrocarbons. Addition of W La found reduce aromatization olefin hydrogenation, and, under almost 100%, the selectivity improved, whereas BTX decreased. amount carbon deposit same that formation may be associated with...
Abstract BACKGROUND: Much attention has been paid to the catalytic conversion of ethanol olefins, since biomass resources such as are carbon‐neutral and renewable, olefins useful both fuels chemicals. It reported that zeolite H‐ZSM‐5 is effective for converting hydrocarbons, with chief products being aromatic compounds. RESULTS: Successive addition Fe P improved initial selectivity propylene, while sole or co‐addition showed medium selectivity. In general, catalysts showing higher propylene...
