A method for removing boron is provided, which includes (a) mixing a carbon source material and a silicon source material in a chamber to form a solid state mixture, (b) heating the solid state mixture to a temperature of 1000° C. to 1600° C., and adjusting the pressure of the chamber to 1 torr to 100 torr. The method also includes (c) conducting a gas mixture of a first carrier gas and water vapor into the chamber to remove boron from the solid state mixture, and (d) conducting a second carrier gas into the chamber.

The invention relates to an integrated method for thermal conversion and indirect combustion of a heavy hydrocarbon feedstock in a redox chemical loop for producing hydrocarbon streams. The heavy hydrocarbon feedstock (1) is brought into contact with inert particles (2) in a thermal conversion zone (100). Thermal conversion in the absence of hydrogen, water vapour and a catalyst produces a first gaseous effluent of hydrocarbon compounds (4) and coke, which effluent is deposited on the inert particles (5). The latter is then burned in a redox chemical loop (200) in the presence of oxygen-carrying solid particles (6). The inert particles thus flow between the thermal conversion zone (100) and a reduction zone (300) of the chemical loop while the oxygen-carrying solid particles flow between the oxidation (400) and reduction zones (300) of the chemical loop.

A process and reactor for contacting a feed stream with a catalyst stream comprises a reaction chamber comprising two spent catalyst inlets for delivering two spent catalyst streams to the reaction chamber and at least one regenerated catalyst inlet for delivering a regenerated catalyst stream to the reaction chamber. The reaction chamber may also include a second regenerated catalyst inlet for delivering a second regenerated catalyst stream to the reaction chamber. The second spent catalyst inlet enables thorough mixing of catalyst streams.

A method for the conversion of a carbonaceous material. The method comprising the steps of providing a carbonaceous material, providing a hot powder material and contacting the carbonaceous material and the powder material in an atmosphere configured to no more than partially oxidize carbon to CO.sub.2. The carbonaceous material is at least a partial converted into volatiles. The volatiles are separated from the additional components by specific gravity.

The present invention provides a safe, disposable and biodegradable chlorine dioxide micro generator that uses water soluble paper and hydrogel or compressed cellulose encased in filter paper pouch. The chemicals are kept in a stabilize form until activated by the addition of water. Multiple levels of protection against early exposure to water such as a foil pouch and an impermeable outer container allow for the safe transportation and storage in small, ready for deployment amounts of the chemicals. Water permeated the chemical pack housing and dissolves the paper walls of the chemical pouch housing and then the water facilitates the reaction between the acid and the sodium chlorite to form chlorine dioxide gas as will be described further hereunder. Absorbent and permeable materials packaged around the chemicals provide for the safe containment of the chlorine dioxide solution, and the expeditious aeration and release of the chlorine dioxide gas, once the chemical reaction has been completed.

Processes and systems for the conversion of hydrocarbons herein may include separating an effluent from a moving bed reactor, the effluent including reaction product, first particulate catalyst, and second particulate catalyst. The separating may recover a first stream including the reaction product and first particulate catalyst and a second stream including second particulate catalyst. The second stream may be admixed with a regenerated catalyst stream including both first and second particulate catalyst at an elevated temperature. The admixing may produce a mixed catalyst at a relatively uniform temperature less than the elevated regenerated catalyst temperature, where the temperature is more advantageous for contacting light naphtha and heavy naphtha within the moving bed reactor to produce the effluent including the reaction product, the first particulate catalyst, and the second particulate catalyst.

An apparatus for producing hydrogen gas is provided. The apparatus includes a first hopper having a reaction chemical. The reaction chemical includes sodium borohydride (NaBH.sub.4) and a chemical component. The chemical component may be magnesium chloride (MgCl.sub.2). The apparatus also includes a reaction chamber. The reaction chamber has an input for receiving the reaction chemical from the first hopper and an output for removal of hydrogen gas. The apparatus also includes a second hopper for containing spent solid chemical mixture removed or extracted from the reaction chamber.
