| 7404889 | Hydrocarbon thermal cracking using atmospheric distillation A method for thermally cracking a hydrocarbonaceous feed wherein the feed is first processed in an atmospheric thermal distillation step to form a light gasoline and atmospheric residuum mixture. The light gasoline/residuum combination is gasified at least in part i... | 07/29/2008 |
| 6410814 | Process for synthesis of lower isoparaffins from synthesis gas A process for synthesis of lower isoparaffins from synthesis gas that is a mixture of hydrogen and carbon monoxide, wherein straight chain hydrocarbons are synthesized while isoparaffins and isoolefins are also produced through decomposition of hydrocarbo... | 06/25/2002 |
| 5780696 | Process for recycling plastic waste The invention relates to a process for recycling waste which consists essentially of one or more plastics comprising polyvinyl chloride (PVC), in which: the waste is mixed with a heavy oil, in a reactor under an inert atmosphere, at an internal temperatur... | 07/14/1998 |
| 4954240 | Combination coking and hydroconversion process A hydrocarbonaceous feed, such as petroleum vacuum distillation bottoms, is upgraded by a combination coking and catalytic slurry hydroconversion process wherein a bottoms fraction from coking is passed to a slurry hydroconversion zone, and the bottoms fr... | 09/04/1990 |
| 4882036 | Combination coking and hydroconversion process A hydrocarbonaceous feed, such as petroleum vacuum distillation bottoms, is upgraded by a combination coking and catalytic slurry hydroconversion process wherein a bottoms fraction from coking is passed through a microfiltration system to remove coke fine... | 11/21/1989 |
| 4839023 | Once-through coking with hydrotreating and fluid catalytic cracking Disclosed is a process for converting heavy hydrocarbonaceous feedstock to more valuable products. The feedstock is introduced into a coking unit containing a coking zone and a scrubbing zone. The bottoms fraction from the scrubbing zone is passed through... | 06/13/1989 |
| 4834864 | Once-through coking with solids recycle Disclosed is a process wherein a scrubber bottom stream from a fluid coker is departiculated by passing it through a microfiltration system. The substantially solids-free filtrate is then upgraded by hydrotreating.... | 05/30/1989 |
