    摘要： A catalyst for the hydrogenation of a hydrocarbon material which is a member selected from the group consisting of red mud, iron oxides, iron ores, hard coals, lignites impregnated with heavy metal salts, carbon black, soots from gasifiers, and cokes produced by the hydrogenation of virgin residues, the catalyst being comprised of at least two separate particle size fractions such that the combined fractions have a particle size distribution between 0.1 and 2,000 microns with 10-40 wt. % of the particles having a particle size greater than 100 microns, and the mixture of fractions not being represented by a straight line when the accumulative weight of the particles vs. particle size which is plotted on log (minus log) vs. log graph paper has a correlation coefficient R.sup.2 less than 0.96 as determined from the equation: ##EQU1## wherein n is the number of experimental points, y is ln [-ln (n/1000)] and x is ln (dp), wherein dp is the particle size (.mu.m) of the particles.

    摘要： A process for suppressing foam formation in a vessel includes the steps of feeding a liquid and a gas to a vessel at a liquid velocity and a gas velocity respectively; adding particles of a solid material to the liquid, the particles having a particle size and particle density; and selecting at least one of the liquid velocity, particle size and particle density so as to fluidize the particles in the liquid, whereby foam formation in the vessel is suppressed. The particles are preferably liquid phase phobic particles.

    摘要： A method for making an oil soluble coking process additive, includes the steps of: providing mixture of a metal salt in water wherein the metal salt contains a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof; providing a heavy hydrocarbon; forming an emulsion of the mixture and the heavy hydrocarbon; heating the emulsion so as to react the metal salt with components of the heavy hydrocarbon so as to provide a treated hydrocarbon containing oil soluble organometallic compound, wherein the organometallic compound includes the metal and is stable at a temperature of at least about 300° C. The oil soluble additive and a process using same are also disclosed.
