  • Publication number: 20070243381
    Abstract: A granular solid wax particle comprising a highly paraffinic wax having a low T10 boiling point less than 427° C. and an inorganic powder coating; optionally with a layer of higher boiling wax over the highly paraffinic wax having a low T10 boiling point, and an inorganic powder coating over the layer of higher boiling wax. In separate embodiments, a highly paraffinic wax having a T10 boiling point less than 427° C. or a highly paraffinic wax having a needle penetration greater than 3 mm/10 at 25° C. is coated with a powder that adsorbs the wax without being encapsulated by the wax in a hot drop wax test. Also, a process for transporting highly paraffinic wax having a T10 boiling point less than 427° C. as granular solid wax particles. And, a method of making base oil from granular solid wax particles transported from a distant location.

  • Publication number: 20060065573
    Abstract: The present invention relates to transportable product for the transportation of paraffinic wax and methods of transporting using this transportable product. The transportable product comprises 90 to 20 weight % of a hydrocarbonaceous liquid, wherein the hydrocarbonaceous liquid comprises ?75 weight % of a liquid selected from the group consisting of naphtha, heavy oil, distillate, lubricant base oil, and mixtures thereof, and 10 to 80 weight % of wax particles, wherein the wax particles comprise ?90 weight % of wax particles larger than 2.4 mm. The transportable product and methods of transporting according to the present invention are able to accommodate a relatively high weight % of paraffinic wax particles in the transportable product while avoiding interparticle adhesion and clumping by ensuring that the wax particles are not too small and the amount of small wax particles is not excessive.

  • Publication number: 20050004411
    Abstract: Provided is a process for converting methane at a remote natural gas site into ethylene and other products. Methane is converted into syngas which is converted into a low-sulfur liquid hydrocarbon mixture containing less than 1 ppm sulfur via Fischer-Tropsch (FT) syntheses. The low-sulfur Fischer-Tropsch liquids are transferred from the remote site to an existing facility where a sulfur-containing compound or a sulfur-containing hydrocarbon mixture is added to avoid coking problems. The resultant blend of hydrocarbons which has a sulfur content of at least 1 ppm, is fed to a naphtha cracking unit and ethylene recovered.

  • Publication number: 20020045076
    Abstract: The present invention provides a process for suppressing the formation of metal-containing coke during processing of a hydrocarbonaceous material, such as for example a hydrocarbon conversion processes. Electromagnetic radiation is applied to the hydrocarbonaceous material while heating the hydrocarbonaceous material to a temperature above 700 degrees F. The frequency of the electromagnetic radiation is preferably below 300 MHz. The process is particularly useful in the reforming of a hydrocarbon material for operation in a fuel cell.
