    摘要： A process for producing hydrocarbons comprises providing a multi-tubular reactor having at least 100 tubes units containing a catalyst, each tube being between 2 and 5 meters tall and in thermal contact with a cooling fluid; feeding hydrogen and carbon monoxide to each tube at a linear gas superficial velocity less than about 60 cm/s; and converting the gas feedstream to hydrocarbons on the catalyst, wherein the yield of hydrocarbons in each tube is greater than 100 (kg hydrocarbons)/hr/(m3 reaction zone). Each tube may have an internal diameter greater than 2 centimeters. The catalyst may be active for Fischer Tropsch synthesis and may comprise cobalt or iron. The maximum difference in the radially-averaged temperature between two points that are axially spaced along the reactor is less than 15° C., preferably less than 10° C. The catalyst loading or intrinsic activity may vary along the length of the reactor.

    摘要： The production of polymer beads by a suspension polymerization process in which a vinyl aromatic monomer having a free-radical generating catalyst dissolved therein is suspended in an aqueous medium with the aid of from 0.1 to 2.0 percent by weight, based on monomer, of a finely divided phosphate suspending agent in the presence of a modifier and heated to cause the monomer to polymerize into polymer beads is improved by the addition to the suspension of at least about 0.01 percent by weight based on monomer of an adjunct modifier, such as certain aminoalkanecarboxylic acids and N-substituted derivatives thereof. The process of the invention is especially applicable in the preparation of large polymer beads.

    摘要： Attempts to prepare polystyrene by peroxide-initiated suspension polymerization at 125.degree. C resulted in polymer having narrower molecular weight distribution than desired. The problem has been solved by copolymerizing the styrene with from 0.05 to 0.35 weight per cent, based on styrene, of a modifying comonomer consisting of a non-conjugated diolefinic compound having one very reactive olefinic group and one less reactive olefinic group such as, for example, allyl methacrylate.
