摘要： A hydroprocessing process for removing impurities from a feed comprising a hydrocarbonaceous liquid comprises at least one cocurrent, upflow hydroprocessing reaction stage, a vapor-liquid contacting stage and a downflow hydroprocessing reaction stage. The feed and hydrogen react in the upflow stage to produce a partially hydroprocessed liquid and vapor effluent. The vapor contacts a hydrocarbonaceous liquid in the contacting stage, which transfers impurities from the vapor into the liquid. The impurity-enriched contacting liquid mixes with the upflow stage liquid effluent and the combined liquid effluents react with hydrogen in the downflow reaction stage, to form a hydroprocessed product liquid and vapor effluent. Additional product liquid is recovered by cooling and condensing either or both the contacting and downflow stage vapor effluents.

摘要： A means and method for spraying liquid and gas onto and across a particulate bed includes a horizontal liquid distribution tray disposed over the bed containing a plurality of gas and liquid spray distributors extending through the tray. The distributors include separate gas and liquid conduits or pipes having an entrance on top and an exit below, with the exits proximate each other underneath the tray. The conduits are coaxial with a portion of the gas conduit surrounded by the liquid conduit to define an annular space between them for the liquid to flow downwardly through. The gas flows down through the gas conduit, exiting as a gas core surrounded by the downflowing liquid. The gas expands and contacts the surrounding liquid to spray it on the matter below. A liquid spray generating device is located below the gas and liquid exit. Siphon caps automatically provide pulse flow of the liquid. Combining the siphon caps with orifices or slots in the liquid conduit below the siphon line automatically provides both continuous and pulse spray of the liquid onto the bed below.

摘要： A process for hydroprocessing liquid petroleum and chemical streams in a single reaction vessel containing two or more hydroprocessing reaction stages. The liquid product from the first reaction stage is stripped of H.sub.2 S, NH.sub.3 and other dissolved gases, then sent to the next downstream reaction stage. The product from the downstream reaction stage is also stripped of dissolved gases and sent to the next downstream reaction stage until the last reaction stage, the liquid product of which is stripped of dissolved gases and collected or passed on for further processing. The flow of treat gas is in a direction opposite the direction in which the reaction stages are staged for the flow of liquid.

摘要： Disclosed is a catalytic cracking process which includes more than one catalytic cracking reaction step. The process integrates a hydroprocessing step between the catalytic cracking reaction steps in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, the hydroprocessing step is included between the reaction stages, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step.

摘要： The invention is for a two phase gas and liquid mixture reacting in an improved fixed bed reactor having at least one auxiliary bed disposed above the main bed. The auxiliary beds each have separate liquid and gas bypasses comprising hollow tubing of relatively different lengths extending through the auxiliary bed. The gas bypass tubing projects to a greater height above the auxiliary bed than the liquid bypass tubing. This tubing bypass arrangement allows for a low pressure drop bypass of the auxiliary bed to the main bed by the liquid and gas when the auxiliary bed becomes fouled.

摘要： Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.
