摘要:
A process for reducing pressure of a vapor stream wherein the vapor stream rotates a turbine wheel within the turbine to transmit rotational movement to an electrical generator and generate electricity. The resulting lower pressure vapor stream reduces a partial pressure of a hydrocarbon vapor or is injected into a reactor to reduce a temperature in the reactor. A recovered electric power measuring system comprises at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data from a sensor on an electrical powerline connected to a generator of a turbine, the turbine in fluid communication with a vapor stream wherein the turbine reduces the pressure of the vapor stream and the resulting lower pressure vapor stream is injected into a reactor to reduce a temperature in the reactor or to reduce a partial pressure of hydrocarbon vapor in the reactor.

A process for catalytic cracking includes the steps of: (a) contacting a hydrocarbon feed with a catalyst at catalytic cracking conditions; (b) adsorbing hydrogen on the catalyst during cracking; and (c) producing a cracked product, preferably propylene, wherein the catalyst comprises (i) a matrix, (ii) a catalytically active material, and (iii) a hydrogen adsorption material. Another process for catalytic cracking includes the steps of: (a) contacting a hydrocarbon feed with a catalyst at catalytic cracking conditions; (b) contacting the hydrocarbon feed with a hydrogen adsorption material; (c) adsorbing hydrogen on the hydrogen adsorption material during cracking; and (d) producing a cracked product, wherein the catalyst comprises (i) a matrix and (ii) a catalytically active material.

Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.

摘要:
The present subject matter describes processes for increasing overall aromatics and xylenes yield in an aromatics complex. More specifically, the process for increasing overall aromatics and xylenes yield in an aromatics complex accomplishes the increased yields by incorporating an A8-A10 isomerization step into the aromatics complex. This isomerization integration increases the para-xylene.
