Abstract: The present invention relates to a multistage process and catalyst system therefor to convert syngas to aromatics. In a first stage, syngas is converted to a C1-C4 alcohol mixture by contacting syngas with a first catalyst comprising rhodium or copper at moderate temperature. In a second stage, the C1-C4 alcohol mixture is converted into an aromatic product by contact with a second catalyst comprising a molecular sieve and at least one Group 8-14 element, the molecular sieve having a Constraint Index about 1 to 12 and a silica to alumina ratio of about 10 to 100 at effective conversion conditions. The final aromatic product is rich in benzene, toluene, and xylenes (e.g. greater than 50% aromatics on a hydrocarbon basis).

Abstract: Methods and compositions are provided for improving metal dusting corrosion, abrasion resistance and/or erosion resistance for various materials, preferably for applications relating to high-temperature reactors, including dense fluidized bed reactor components. In particular, cermets comprising (a) at least one ceramic phase selected from the group consisting of metal carbides, metal nitrides, metal borides, metal oxides, metal carbonitrides, and mixtures of thereof and (b) at least one metal alloy binder phase are provided. Ceramic phase materials include chromium carbide (Cr23C6). Metal alloy binder phase materials include β-NiAl intermetallic alloys and Ni3Sn2 intermetallic alloys, as well as alloys that contain α-Cr and/or γ′-Ni3Al hard phases. Preferably, bimetallic materials are provided when the cermet compositions are applied using a laser, e.g., a laser cladding method such as high power direct diode (HPDD) laser, or by plasma-based methods such as plasma transfer arc (PTA) welding and powder plasma welding (PPW).

Abstract: Processes for preparing a low particulate liquid hydrocarbon product are provided and include blending a tar stream containing particles with a fluid and heating to a temperature of 250° C. or greater to produce a fluid-feed mixture that contains tar, the particles, and the fluid. The fluid-feed mixture contains about 20 wt % or greater of the fluid, based on a combined weight of the tar stream and the fluid. Also, about 25 wt % to about 99 wt % of the particles in the tar stream are dissolved or decomposed when producing the fluid-feed mixture.

Abstract: A multi-stage process is described for upgrading pyrolysis tar, such as steam cracker tar, by hydroprocessing in at least two stages. Hydroprocessing in a first stage is performed in the presence of a utility fluid. The utility fluid has a boiling point distribution from about 120° C. to about 480° C. and is separated from the first stage product.
