A method and assembly for utilizing open-cell cellular solid material in a component separation unit to separate one or more process streams into component process streams having desired compositions. A method and assembly for using said open-cell cellular solid material to separate process streams into desired component process streams in a component separation unit, wherein the open-cell cellular solid material can include oxides, carbides, nitrides, borides, ceramics, metals, polymers, and chemical vapor deposition materials.

Separation method and assembly for process streams in component separation units

Disclosed is an alternative fuel composition derived from the conversion of biomass at an elevated temperature, with conversion optionally in the presence of a catalyst, which is capable of reducing, and thereby improving, a low temperature property of a distillate. A process is also disclosed for mixing such renewable composition with the distillate.

Method of using renewable fuel composition

Disclosed is a process for the alteration of the ratio of the specific gravities of the oil and water phases resulting from the conversion of biomass to liquid products, the reduction of the conductivity and of metals of the product mixture, which each can aid in the removal of solids contained in the oil phase.

Process for upgrading biomass derived products

A renewable fuel may be obtained from a bio-oil containing C-Coxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C+ oxygenates. In a second step, the stream is hydrotreated to produce C+ hydrocarbons.

Process of generating a renewable biofuel from a hydrotreated stream of condensed oxygenates

A method for continuous monitoring the presence of entrained catalyst in a regenerator flue gas stream of a fluidized catalytic cracking unit is provided. The method has the following steps: (a) passing the regenerator gas stream through a separation system to remove a portion of the catalyst fines and to create a cleaner regenerator gas stream; (b) collecting a sample portion of the cleaner regenerator gas stream and directing the sample portion of the cleaner regenerator gas stream through an inertial separating device to separate entrained catalyst from the sample portion of the cleaner regenerator gas stream; (c) collecting any separated catalyst from the inertial separating device; and (d) monitoring the efficiency of the separation system by analyzing at least the amount of the collected separated catalyst or the particle size of the collected separated catalyst. An apparatus for measuring the amount of potentially erosive catalyst fines in a regenerator flue gas stream in a fluidized catalytic cracking unit is also provided. The apparatus is a sampling probe for collecting a sample portion of the regenerator flue gas from a line through which the regenerator flue gas stream flows, and an inertial separating device located downstream of the sampling probe and in fluid communication therewith, for removing any entrained catalyst fines from the sample portion of the regenerator flue gas.

Process for determining the amount of erosive material entering a power recovery turbine

A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added around a clean gas outlet tube in a cyclone body. Solids and some gas are withdrawn via a solids outlet and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body via an opening in the cyclone. Chaotic reflux of gas back into the cyclone via the solids outlet is eliminated. The device may be used as an FCC regenerator third stage separator or to improve other gas/solid separations.

Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst comprising zeolite beta. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

Gasoline upgrading process

Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst under endothermic conditions in a second reaction zone. Heat is added to the endothermic reaction zone to initiate and maintain octane restoring reactions. The preferred acidic catalyst is an intermediate pore size zeolite such as ZSM-5. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The addition of heat at the second zone prolongs hydrodesulfurization catalyst life by allowing a lower hydrodesulfurization reactor temperature. The addition of heat also maximizes octane increase in the second zone.

Hydrocarbon upgrading process

Low sulfur gasoline is produced from a catalytically cracked, sulfur-containing naphtha by fractionating the naphtha feed into a low boiling fraction in which the majority of the sulfur is present in the form of mercaptans and a high-boiling fraction in which the sulfur is predominantly in non-mercaptan form such as thiophenes. The low boiling fraction is desulfurized by a non-hydrogenative mercaptan extraction process which retains the olefins which are present in this fraction. The second fraction is desulfurized by hydrodesulfurization, which results in some saturation of olefins and loss of octane. The octane loss is restored by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5, to form a low sulfur gasoline product with an octane number comparable to that of the feed naphtha but which contains some recombined sulfur in the form or mercaptans which are removed in the non-hydrogenative mercaptan extraction step.

Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst defined by its x-ray diffraction pattern and preferably comprising the synthetic zeolite MCM-22. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

Catalytic cracking of hydrocarbon feedstocks is improved by hydrotreating the cracking feed under conditions of relatively low temperature, typically below 390.degree. C. for start-of-cycle, and high pressure, typically above 10,000 kPa, preferably above 12,000 kPa. The use of these conditions favors aromatics saturation to produce a cracking feed of improved crackability so that higher conversion is achieved in the cracking step at constant cracking conditions with production of naphtha of good octane quality. At the same time, desulfurization is achieved to maintain cracker SO.sub.x emissions at required levels; the advantages of high pressure operation are more notable at high denitrogenation severities while still achieving a low catalyst aging rate.
