查询词典 steaming feed

Adding 3. 2vol% steam in feed gas CH〓 conversion increased to 94%, the CO〓 conversion was maintained in 98%, and the less carbon was deposited, the stability might be more excellent.

添加3.2vol％的水蒸汽后，CH〓转化率提高到94％，CO〓的转化率保持98％不变，H〓/CO比约有0.06的提高，同时积碳更少，稳定性也可能更好。

On the other hand, steam can be used to restrain the side reaction such as hydrogen transfer reaction so as to increase the yield of light olefins by diluting the concentration of the reactant. In addition, minor steam can react with the feed hydrocarbon resulting in the decrease of coke and the formation of active hydrogen without the increase of hydrogen gas and light saturates that is not desirable.

另一方面，水蒸气不仅仅具有降低烃分压的作用，抑制了氢转移反应等副反应，对于低碳烯烃的产率有好的影响，而且在反应过程中，少量参与了反应，与烃类发生了水煤气反应，生成了活泼氢，不仅降低了焦碳的产率，并且没有提高氢气、低碳烷烃等不希望得到的产物。

The effects of operation condition, such as type of coal, coal feed rate, steam/coal ratio and air/coal ratio on gas composition, calorific value, carbon conversion and gasification efficiency are analyzed.

以空气和水蒸气为气化剂，在循环流化床煤气化热态试验台上进行了神华煤、龙口煤和大同煤的气化试验，研究了煤种、加煤速率、空气煤比、蒸汽煤比对气化过程的影响。

Compression-type valve: This valve is used as boiler feed water and steam off with a valve, it has a lift check valve and stop valve or angle valve integrated function.

压紧式止回阀：这种阀门是做为锅炉给水和蒸汽切断用阀，它具有升降式止回阀和截止阀或角阀的综合机能。

Carbon is easier to react with steam than α-carbon, therefore adding a small amount of steam in feed gas can obviously suppress β-carbon deposit.

碳比α-碳更容易同水蒸汽作用，添加少量水蒸汽到反应气中能够明显抑制β-碳的生成。

The latter could be eliminated more preferentially than the former by steam, so the amount of the latter was obviously suppressed by adding steam in feed gas.

碳比α-碳更容易同水蒸汽作用，故水蒸汽的添加能够明显的减少积碳。

In the thesis, efficiency calculation of the power plant feed pump driving steam turbine in the unit operation is mainly analyzed, concerning the variant working condition economical analysis of this turbine.

From the consistency of steam explosion pretreatment and feed production by SSF of treated maize stalk, steam explosion was used to treat maize stalk and produce the substrate for fermentation.

首先从汽爆预处理与汽爆秸秆固态发酵生产饲料的统一性考虑，系统探讨了汽爆压力和时间、秸秆含水量和添加氮源对汽爆秸秆化学组成及微生物发酵的影响。

Due to the suppression of reverse water gas shift reaction by adding steam in feed gas, more CO〓 participated in and promoted CO〓 reforming of CH〓 reaction, higher catalytic activity and less carbon deposition were obtained. On the surface of used catalyst there were two kinds of carbon species deposited on catalyst, one was decomposed CH〓 fragment, and the another was graphiticlike carbon.

在反应后催化剂表面有两类碳物种，一类在250～350℃出现的少量α-碳，应主要是活性高的CH〓解离碎片，一类是在700℃附近出现的β-碳，应是导致催化剂失活的类石墨化碳。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
