    摘要： Heavy liquid hydrocarbon oil, such as petroleum derived tars, predominantly boiling over 425.degree. C., are upgraded to products boiling below 425.degree. C., without substantial formation of insoluble char, by heating the heavy oil with hydrogen and a hydrogen transfer solvent in the absence of hydrogenation catalyst at temperatures of about 320.degree. C. to 500.degree. C., and a pressure of 20 to 180 bar for 3 to 30 minutes. The hydrogen transfer solvents are polycyclic compounds free of carbonyl groups, e.g., pyrene, and have a polarographic reduction potential which is less negative than phenanthrene and equal to or more negative than azapyrene.

    摘要： Hydrogen conservation in solvent refining of coal is practiced and solvent compositions and adjusted to needs of two stage operation. The first stage is a short residence time dissolution in a recycle solvent rich in phenols and polyaromatics of high boiling range. The solvent is enriched for the second stage in low boiling hydrogen donors and the product of the process undergoes hydrotreating in an integrated process.

    摘要： Novel amorphous siliceous materials having shape-selective sorption properties are prepared by a novel process of (1) hydrolyzing an organosilicon compound of the formula R[Si]X.sub.3 alone or in the presence of one or more compounds either of the formula R'.sub.n MY.sub.m, wherein R and R' are non-hydrolyzable organic groups, X is a hydrolyzable group, Y is the same as X or oxygen, [Si] is silicon or ##STR1## M is metal or non-metal, including silicon, of any group of the Periodic Table other than IA, IIA, VIIA or O, m is a number over 0 and up to 8 and n is 0 or a number less than 8, or an inorganic compound consisting of an anionic portion made up of M and Y and a cationic portion of either hydrogen, alkali or alkaline earth metal or ammonium; (2) effecting condensation polymerization of the hydrolyzed product; and (3) calcining the resulting polymerized product to convert all the R and R' groups to hydroxy or hydrogen. Pore size distribution of the final composition is primarily controlled by appropriate selection of the R group of the R[Si]X.sub.3 precursor. The amorphous synthetic solids of this invention are useful in such conversion processes as shape-selective cracking, hydrocracking, hydrogenation-dehydrogenation, oxidation, and methanation processes. They are also useful as sorbents and catalyst supports.
