    Abstract: This invention relates to the catalytic carbonylation of .alpha.,.alpha.'-dihaloxylenes to phenylenediacetate diesters by the catalytic insertion of carbon monoxide into the carbon-halogen bonds of said .alpha.,.alpha.'-dihaloxylenes in the presence of alkanols. The catalysts used in this novel process are two component homogeneous ligand-stabilized palladium(II) and nickel(II) halide complexes wherein said stabilizing ligands each contain at least one Group VB or VIB donor atom such as phosphorus, which is bonded to one or more aromatic and/or aliphatic radicals.

    Abstract: A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, alkali metal compounds, hydrogen halides, hydrogen cyanide, sulfur-containing gases, and with or without ammonia for use as synthesis gas, reducing gas, or fuel gas. A pumpable hydrocarbonaceous fuel selected from the group consisting of liquid hydrocarbonaceous fuel or liquid emulsions thereof, an aqueous slurry of petroleum coke, and mixtures thereof and wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H.sub.2, CO, CO.sub.2, H.sub.2 O, CH.sub.4, NH.sub.3, HCN, HCl, HF, H.sub.2 S, COS, N.sub.2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is cooled in a radiant cooler and cleaned. Optionally, ammonia is removed from the gas stream by being catalytically disproportionated into N.sub.2 and H.sub.2. The process gas stream is cooled and halides and HCN in the gas stream are reacted with a supplementary alkali metal compound to remove HCl, HF and HCN. Alkali metal halides and alkali metal cyanide, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000.degree. F.

    Abstract: A process for the production of demercurized synthesis gas, reducing gas or fuel gas. Mercury-containing fossil fuels e.g. coal were reacted by partial oxidation to produce gaseous mixtures comprising H.sub.2, CO, H.sub.2 O, CO.sub.2, H.sub.2 S, COS, entrained slag and/or ash, mercury vapor, and optionally CH.sub.4, NH.sub.3, N.sub.2 and Ar. Unexpectedly, the mercury vapor was produced in the reaction zone; and it was found to be thermodynamically stable even in the presence of H.sub.2 S under the strong reducing conditions that prevailed in the gas generator. No new sulfides of mercury were formed. The mercury vapors were removed from the main body of the process gas stream in a pressurized solvent scrubber at a relatively low temperature. By this means, the mercury vapor was condensed and simultaneously the mercury and sulfur contents of the clean process gas stream were reduced to low levels. In one embodiment, the last vestiges of mercury were removed from the demercurized product gas stream by carbon sorption.
