    摘要： A process for preparing molecular sieves of type Y faujasite structure is described, as well as pre-shaped bodies of faujasite structure type Y molecular sieves. The process comprises preparing a precursor gel from a source of silica-alumina or a source of alumina and a source of silica with a template agent at a SiO2/Al2O3 greater than 7 and suitable for forming a type Y zeolite, drying the precursor gel and contacting the dried precursor gel with steam, optionally followed by caustic washing, without the formation of crystalline phases other than type Y zeolite being observed. Advantageously, the pre-shaped bodies prepared with the precursor gel of Y zeolite, when subjected to the process of the invention, will have their outer surface covered by type Y zeolite crystals. The molecular sieves so obtained may be employed as catalysts or adsorbents in various processes of the chemical or oil industry.

    摘要： A peak detect-and-hold circuit eliminates errors introduced by conventional amplifiers, such as common-mode rejection and input voltage offset. The circuit includes an amplifier, three switches, a transistor, and a capacitor. During a detect-and-hold phase, a hold voltage at a non-inverting in put terminal of the amplifier tracks an input voltage signal and when a peak is reached, the transistor is switched off, thereby storing a peak voltage in the capacitor. During a readout phase, the circuit functions as a unity gain buffer, in which the voltage stored in the capacitor is provided as an output voltage. The circuit is able to sense signals rail-to-rail and can readily be modified to sense positive, negative, or peak-to-peak voltages. Derandomization may be achieved by using a plurality of peak detect-and-hold circuits electrically connected in parallel.

    摘要： A process is disclosed for converting aquatic biomass to a bio-oil. The process comprises mixing the aquatic biomass with a particulate catalytic material; subjecting the aquatic biomass to a catalytic cracking reaction to form a reaction mixture comprising a bio-oil; and isolating the bio-oil from the reaction mixture. Preferably the process is integrated with a plant for producing aquatic biomass, so that heat and CO2 generated during the process may be used in the production of aquatic biomass.
