摘要： In an ethylene manufacturing process in which the effluent from the cracking furnaces is provided to an acetylene reactor to therein selectively hydrogenate acetylene to ethylene, method and apparatus is provided whereby methanol is injected into the cracking furnace to produce carbon monoxide in sufficient quantities to substantially optimize the selectivity of the conversion of acetylene to ethylene in the acetylene reactors. The concentration of the carbon monoxide in the effluent flowing from the cracking furnace is utilized to manipulate the flow of methanol to the cracking furnace so as to maintain a desired concentration of carbon monoxide in the effluent flowing from the cracking furnace.

摘要： The formation and accumulation of coke or other reaction by-products of olefins produced by the pyrolysis of hydrocarbons is prevented. This is accomplished by maintaining the transfer portion extending from the outlet port of the pyrolysis reaction tube to the multi-tubular quenching device at a temperature below 450.degree. C. This technique is especially applicable to the manufacture of olefins by the pyrolysis of hydrocarbons which are gaseous at room temperature under atmospheric pressure or liquid hydrocarbons having a volumetric average boiling point of below 90.degree. C., at temperatures ranging from 750.degree. to 900.degree. C., followed by quenching in a multi-tubular quenching apparatus. It is only necessary to cool the transfer portions to a temperature below 450.degree. C. in those areas where cracked gas is flowing at a flow rate below 50 kg/m.sup.2 per sec.
摘要翻译：通过烃的热解产生的烯烃的焦炭或其他反应副产物的形成和积聚被阻止。这是通过将转化部分从热解反应管的出口延伸到多管状淬火装置的温度低于450℃来实现的。该技术特别适用于通过烃的热解制备烯烃，在常压下在室温下气态或在750℃至900℃的温度范围内具有体积平均沸点低于90℃的液体烃，然后在多管式淬火装置中淬火。只有在裂解气体以低于50kg / m 2 /秒的流量流动的区域中，才需要将转移部分冷却至低于450℃的温度。

摘要： Coal is continuously converted into a saturated hydrocarbon gas containing substantially no unsaturated hydrocarbon and having a high calorific value and a uniform composition by the operations of: providing a first treating gas having a predetermined temperature, pressure and composition, by mixing, in a first conditioning chamber, a first substantially inert burnt gas which has been prepared by burning a mixture of a fuel and air, containing therein 2% by volume or less of free oxygen, with steam and, if necessary, hydrogen gas; thermally cracking, in a first treating chamber, the coal particles with the first treating gas while fluidizing said coal particles; separately providing a second treating gas having a predetermined temperature, pressure and composition by mixing, in a second conditioning chamber, a second substantially inert burnt gas which has been prepared by burning a fuel, and contains therein 2% by volume or less of free hydrogen gas, with hydrogen gas and, if necessary, an additional gas; hydrogenating, in a second treating chamber, the thermally cracked product with the second treating gas while fluidizing the thermally cracked product to generate the saturated hydrocarbon gas and isolating the saturated hydrocarbon gas from the hydrogenation mixture, the hydrogen gas used in the above process being prepared by collecting char from the hydrogenation mixture, converting the char into water-gas containing hydrogen and carbon monoxide gases by treating with a third treating gas containing steam, converting the carbon monoxide into a mixture of hydrogen and carbon dioxide gases by steam treatment and isolating the hydrogen gas from the conversion mixture.

摘要： A process for the preparation of ethylene and propylene wherein n-butane is cracked at high pressure in the presence of steam, preferably with ammonia in a reactor containing a solid support, at a temperature of from 550* to 750* C. for a residence time of 0.2 to 15 seconds to convert 40 to 90 percent of the n-butane. The reaction product is cooled and methane separated therefrom at a pressure not greater than that in the cracking reaction. The C4 fraction separated from the reaction product is recycled to the cracking step.

摘要： THE PRESENT INVENTION RELATES TO AN IMPROVED PROCESS FOR THERMALLY DECOMPOSING ORGANIC COMPOUNDS IN CONTACT WITH ALLOY STEEL, E.G., THE CRACKING OF LOW MOLECULAR WEIGHT HYDROCARBONS IN HEAT-RESISTANT ALLOY STEEL FURNACE TUBES TO PRODUCE OLEFINS OR ACETYLENES. BY THE PRESENT INVENTION, HEAT-RESISTANT ALLOY STEEL COMPRISED OF AT LEAST 1% BY WEIGHT SILICON IS EMPLOYED, AND A CARBURIZATIONRESISTANT PROTECTIVE FILM COMPRISED OF SILICON OXIDATION COMPOUNDS IS FORMED THEREON. THE PROTECTIVE FILM IS FORMED BY PRETREATMENT OF THE ALLOY WITH STEAM PRIOR TO THERMALLY DECOMPOSING THE ORGANIC COMPOUND THEREIN AND/OR BY COMBINING A SMALL AMOUNT OR STEAM WITH THE ORGANIC COMPOUND SO THAT THE PROTECTIVE FILM IS FORMED DURING THE THERMAL DECOMPOSITION.

摘要： A fired heater having two parallel vertical radiant sections essentially completely separated from each other and a convection section above and offset from both radiant sections with each radiant section having a single row of process tubes which are fired from both sides, with tubes of each section being interconnected with each other by horizontal crossover tubes to provide for flow of process fluid from inlet to outlet through both sections. The inlet radiant section may be fired at higher heat rates to heat a fluid to be processed from an inlet temperature to an intermediate temperature in a short residence time. The heater may be employed for: heating a mixture of carbon monoxide and hydrogen; pyrolysis of hydrocarbons; or steam reforming of hydrocarbons.
