The invention relates to inhibiting the degradation of fuel oils by the addition of phosphines and phosphites. Additionally, the invention relates to inhibiting the degradation of fuel oils by drying the fuel oil and adding phosphines and phosphites.

Fuel with stability additive and process for stabilizing fuel using an

Indole impurities are removed from hydrocarbon-containing fluids by means of a magnesia-containing sorbent material.

Separation of indole from hydrocarbons

Esters are prepared by contacting, under suitable reaction conditions, a feed stream comprising a primary alcohol of 1-4 carbon atoms per molecule (preferably methanol, ethanol) and carbon monoxide with a catalyst composition comprising (a) copper or a copper compound (preferably CuO), (b) zinc oxide, (c) at least one metal or compound of at least one metal selected from the group consisting of cobalt, ruthenium, iridium, platinum, molybdenum, and rhenium (preferably cobalt and/or rhenium) and, optionally, (d) alumina.

Synthesis of esters from alcohols containing carbon monoxide as an

A process for producing higher ketones comprises the step of contacting under suitable conditions a feed comprising at least one C.sub.2 -C.sub.6 aliphatic aldehyde, and preferably also carbon monoxide, with a catalyst composition comprising (i) copper and/or an oxide thereof and (ii) zinc oxide. Preferably, the feed aldehyde is propanal, and the product comprises at least one C.sub.5 ketone. Ketones are substantially absent from the aldehyde feed.

Synthesis of ketones from aldehydes

A process for converting synthesis gas (CO+H.sub.2) to aliphatic alcohols containing at least 2 carbon atoms comprises the steps of passing the synthesis gas first through a catalyst zone comprising (a) Co metal and/or Co oxide and (b) MgO and/or ZnO (preferably MgO), and then through a catalyst zone comprising (c) Cu metal and/or Cu oxide and (d) ZnO.

Preparation of alcohols from synthesis gas

A Fischer-Tropsch catalyst is prepared using a solvated metal atom technique. The thus formed catalyst is active for the conversion of carbon monoxide and hydrogen to hydrocarbons though it contains less than about 5% metal by weight of the catalyst.

Fischer-Tropsch catalysts

Higher ketones are prepared by contacting, under suitable reaction conditions, a feed stream comprising (a) a primary alcohol of 2-6 carbon atoms per molecule (preferably ethanol, 1-propanol or 1-butanol) and (b) carbon monoxide with a catalyst composition containing copper oxide, zinc oxide and, optionally, alumina.

Synthesis of ketones from alcohols

The preparation of alcohols from synthesis gas has been beneficiated by the use of a novel five-component catalyst system comprising an iron group metal and an activity improving amount of a precious metal such as rhodium.

Catalyst for alcohol synthesis

Alcohol synthesis

Dienes such as 1,3-butadiene, in relatively low concentration, are removed from mono-olefins, such as propylene and normal butenes, by passage over a catalyst of activated magnesium oxide while irradiated with ultraviolet light.

Removal of diene impurities from alkenes or alkanes over activated

One or more olefinically unsaturated nitriles are converted to other nitriles by contact with a catalyst active for the disproportionation of propylene to ethylene and butene.

Conversion of olefinic nitriles

A process for the conversion of at least one olefinic organic compound by disproportionation, proportionation, and/or isomerization, in which an olefin conversion catalyst is exposed to electromagnetic radiation prior to and/or during contact of the organic compound with the catalyst. The catalyst may also be pretreated with ethylene, propylene and/or butene during exposure to radiation or the olefinic compound may be pretreated by contact with magnesium oxide while exposing the magnesium oxide to radiation.

Conversion of olefinic compounds

Purity of hydrocarbon streams is increased by contacting with stable oxides of calcium, titanium, zinc, or zirconium prior to passage to a catalytic conversion process. In one embodiment, the stable metal oxides are preactivated by heating with vaporous hydrocarbon at an elevated temperature which is effective in extending the temperature at which metal oxides are subsequently effective for purification of hydrocarbon streams.

Purification of monoolefin-containing hydrocarbon stream

Monoolefins are hydrogenated in the presence of a catalyst comprising at least one carbide, nitride, or silicide of a Group VIII, Group VIB, or Group VIIB metal.
