    摘要： A combined process for the conversion of solid starting particles into solid intermediate particles and reducing the median diameter of the intermediate particles to obtain product particles. This process involves flowing a suspension of starting particles through a series of at least two conversion vessels, thereby converting at least part of the starting particles into intermediate particles, adding a supercritical fluid to one or more of the conversion vessels, thereby forming a supercritical suspension, and releasing pressure from the supercritical suspension, thereby expanding the suspension and converting the intermediate particles into product particles.

    摘要： A continuous process for the hydrothermal conversion of a solid starting iron compound selected from the group of iron oxides, iron hydroxides, iron oxyhydroxides, and mixtures thereof into a solid product iron compound with different physical, chemical, and/or structural properties. The process comprises the steps of a) dispersing the solid starting iron compound in a liquid thus forming a suspension, and b) feeding the suspension continuously though one or more agitated conversion vessel(s), in which vessel(s) the solid starting iron compound is converted into the solid product iron compound under hydrothermal conditions.

    摘要： The present invention pertains to A cyclic process for testing FCC catalysts with resid feedstock on a small scale wherein in a first cycle: a) the feed to be cracked is heated to a temperature between 50 and 500° C., b) the heated feed is injected into a riser reactor containing the FCC catalyst to be tested having a temperature between 500 and 800° C., the injection time being less than 2 seconds, c) an inert gas is injected into the lower end of said reactor riser together in the vicinity of the feed injection in a volume ratio of inert gas to vaporized feed of about 0.03 and 10, the mixing of feed and inert gas occurring in said riser reactor; d) the feed is contacted with the FCC catalyst under fluidized conditions for a contact time of less than 8 seconds; e) the feed is stripped from the FCC catalyst and the properties of the product are analyzed; and in a second cycle a quench liquid is injected into said riser reactor in an amount of up to about 20 wt.% of said feed so as to reduce the temperature in said riser reactor and minimize undesirable secondary reactions. The invention also comprises the apparatus employed to carry out the process. With the process of the invention the mass transfer and diffusion limitations of commercial FCC units are properly simulated.

    摘要： A process is described for pretreating lignocellulosic biomass. The process comprises swelling the lignocellulosic biomass with an aqueous liquid. The pretreated lignocellulosic biomass may be used as a feedstock for the enzymatic conversion to ethanol, or in a thermal conversion. process to produce bio-oil. The pretreatment results in a greater yield and, in the case of a thermal conversion process, a better quality of the bio-oil. The pretreatment process may be used to adjust the composition and amount of inorganic material present in the lignocellulosic biomass material.
