This invention relates to an apparatus and a process for conversion of syngas into one or more hydrocarbons in presence of Fisher-Tropsch catalyst comprising in-situ catalyst activation in a separate fluid bed reactor. Activation is carried out in the dry phase in flowing hydrogen atmosphere in ...
A gas is dissolved into a liquid by first pressurizing the liquid to a predetermined level. The pressurized liquid is then directed into a hydrocyclone to form a vortex stream having an evacuated cent
a rotatable hollow body provided with discharge openings and which is rotating in a space containing gas, jets of liquid discharging through the openings impinging on the wall of a container in which the hollow body is located, the liquid being reduced to drops in the space containing gas. The...
A process for the conversion of synthesis gas to liquid hydrocarbon products by contacting the synthesis gas at temperature of between, 180.°C and 280 and a pressure of between 5 and 50 BAR with a suspension comprising catalyst suspended in a liquid medium, in a system comprising a tank rea...
A. evaporation B. condensation C. sublimation D. precipitation 相关知识点: 试题来源: 解析 A。本题考查科学术语。evaporation 是“蒸发”,即从液体变为气体的过程;condensation 是“凝结”,从气体变为液体;sublimation 是“升华”,从固体直接变为气体;precipitation 是“降水”。反馈 收藏 ...
试题来源: 解析 A。本题考查科学概念的英文表述。“evaporation”意思是蒸发,液体变为气体的过程就是蒸发。B 选项“condensation”是凝结,是气体变为液体的过程。C 选项“precipitation”是降水。D 选项“sublimation”是升华,是固体直接变为气体的过程。反馈 收藏 ...
试题来源: 解析 A。解析:蒸发(evaporation)是水从液态变为气态的过程,这符合题目描述。选项B,condensation是气态变为液态的凝结过程,与题目要求不符。选项C,precipitation是降水过程,包括雨、雪等形式,不是液态到气态的转变。选项D,infiltration是入渗过程,指水渗入土壤等,和液态到气态的转变无关。
The device (100) for dissolving the gas in the liquid includes gas injection means (14) for introducing gas into the liquid and a contact chamber (20) for containing a downflowing stream of the liquid to be treated. The pressure within the downflowing stream increases as it descends and at...
removal location and then gas-lifting liquid by injecting an aqueous liquid solution which generates nitrogen gas within the borehole, with the depth of the injection and the rates of fluid inflow and outflow being adjusted to maintain a selected drawdown at the depth of the fluid- removal ...
The effect of ceria promotion over Ni/Al 2 O 3 catalysts on the catalytic activity and coke formation was investigated in combined steam and carbon dioxide reforming of methane (CSCRM) to produce synthesis gas (H 2 /CO=2) for gas to liquid (GTL) process. Ce-promoted Ni/Al 2 O 3 ca...
