Compositions for Catalytic Gasification of a Petroleum Coke

InactiveUS20090090055A1Improved gasification activityCost-effective and high-yielding productionHydrogenGaseous fuelsParticle compositionChemistry
The present invention relates to particulate compositions of a lower ash type petroleum coke containing at least two preselected components (alkali metal and iron) that exhibit an efficient, enhanced-yielding gasification to value added gaseous products, particularly when used in a steady-state integrated gasification process. The compositions of the present invention are particularly useful for catalytic gasification of petroleum coke at moderate temperatures ranging from about 450° C. to about 900° C. Advantageously, the compositions can be readily incorporated into fluidized bed gasification units, and can result in a cost-effective, high-yielding production of methane gas from petroleum coke.

Control of Fluid Catalytic Cracking Process for Minimizing Additive Usage in the Desulfurization of Petroleum Feedstocks

A method and apparatus for the cracking of a petroleum oil feedstock to produce a desulfurized full-range gasoline product. The petroleum oil feedstock is contacted with a base cracking catalyst and an FCC additive in an FCC unit, wherein the catalyst includes a stable Y-type zeolite and a rare-earth metal oxide and the additive includes a shape selective zeolite. The catalyst, additive and petroleum oil feedstock can be contacted in a down-flow or riser fluid catalytic cracking unit, that can also include a regeneration zone, a separation zone, and a stripping zone. The FCC unit includes an integrated control and monitoring system that monitors at least one parameter selected from FCC operating parameters, feed rate, feedstock properties, and product stream properties, and adjusts at least one parameter in response to the measured parameter to increase production of desulfurized products.

Battery pack

A battery pack is made up of a plurality of flat prismatic batteries arranged face to face, each battery having one electrode terminal protruding from one end face in the height direction of the battery case and this end face or a side face of the battery serving as the other electrode terminal. The connector for electrically connecting adjacent prismatic batteries includes a flat part that is welded to one electrode terminal of one prismatic battery of the adjacent prismatic batteries, and a cylindrical part that is fitted onto and welded to the other electrode terminal of the other prismatic battery. The cylindrical part is formed in an attachment part that extends from the flat part through an upright part in the direction in which the batteries are aligned. The connector enables reliable electrical connection of the prismatic batteries despite possible variation in height of the electrode terminals.

Centralized secondary fermentation method for agaricus bisporus

The invention discloses a centralized secondary fermentation method for agaricus bisporus. The culture medium comprises the following raw materials in parts by weight: 45-60 parts of forage, 35-50 parts of chicken manure, 2-8 parts of gypsum and 3-10 parts of oil cakes. The method comprises the following steps of: uniformly spreading forage in a pre-wetting pool for pre-wetting for 2-5 days; adding chicken manure, gypsum and oil cakes and uniformly and adequately mixing; filling the mixed fermentation material in a ventilating floor in a primary fermentation tunnel, and conveying fresh air to the fermentation material through a fan; fermenting for 4-6 days and transferring the fermentation material to another primary fermentation tunnel. The base material of the primary tunnel fermentation is uniformly stacked on the ventilating floor in a secondary fermentation tunnel, and the temperature of the fermentation material is controlled by operation of the fan. Secondary fermentation comprises the following steps: a balancing stage, a heating stage, pasteurization, cultivation at constant temperature and discharge at low temperature. According to the method, local wheat straw hoods, straws, chicken manure and the like are used as main raw materials to form the culture medium. Centralized scaled production cultivation materials are formed by the technology of pre-treatment of the raw materials, primary fermentation and secondary fermentation.

Method for regulating the ink in a printing press

The ink in a printing press, in which a stock of material is being printed in an ongoing printing process, is registered. At least one ink is applied to the stock in several inking zones. A measured value, indicating an ink density, is determined for the at least one ink which is being applied to the stock in the printing process and within the printing press. A relation is formed between the measured ink density for a specific ink in a selected ink zone and a measured ink density value determined for the same ink in at least one other inking zone. The relation between the measured ink density values in different inking zones is formed only if the majority of the inking zones of a specific inking unit of the printing press supply one respective measured ink density value for an ink supplied by that inking unit, and when the measured ink density value reaches at least a predetermined fraction of a preset, desired value in the respective inking zone.

The invention provides a phenyl hydrazine and substituted phenyl hydrazine continuous flow synthesis process. Three-step reactions of diazotization, reduction and acidolysis salt formation are creatively and organically integrated; phenylamine or substituted phenylamine acid material liquid, diazotization reagents, reducing agents and acid are used as raw materials to be subjected to three-step reaction of diazotization, reduction and acidolysis salt formation to obtain phenyl hydrazine derivative salts. The synthesis process is performed in an integral reactor, and belongs to an integrated solution. The reaction raw materials are continuously added through a feeding opening of the integral reactor; the reactions of diazotization, reduction and acidolysis salt formation are continuously performed in the integral reactor; the phenyl hydrazine derivative salts are continuously obtained in the integral reactor; the total reaction time is less than or equal to 20min. Compared with a conventional production process, the continuous flow synthesis process has the advantages that the total reaction time is greatly shortened; the safety is greatly improved; no reaction byproducts (such as diazoamino compounds and reduction reaction midbodies) are included in the reaction process and the reaction products; the continuous flow process can prepare the high-purity products with the purity as high as 99 percent or higher without the additional purification steps.
