The hydriding reaction with hydride materials such as ZrCo, which has low hydrogen equilibrium pressure at room temperature, can be used in the helium-3 purification process to remove tritium impurity from a mixture of helium-3 and tritium. However, the helium interferes with the hydriding reaction, so it is necessary to confirm whether the helium affects the reduction of the tritium partial pressure to the equilibrium pressure of ZrCo tritide. Various hydrogen and helium mixtures were applied to the hydriding reaction under two reaction temperatures and two final H/M ratios to determine whether helium affects the reduction of the hydrogen partial pressure. Regardless of the helium fractions in the feed gases, residual hydrogen pressures were similar to the equilibrium pressure of ZrCo hydride under the different temperature and final H/M ratio conditions. Applying ZrCo hydriding reaction with a circulation loop, the helium-3 purification process can efficiently remove the tritium impurity without creating the blanketing effect.

与氢化物材料（例如ZrCo）的氢化反应在室温下具有较低的氢平衡压力，可用于氦3提纯工艺中，以从氦3和tri的混合物中除去tri杂质。然而，氦会干扰氢化反应，因此有必要确认氦是否影响partial分压降低至ZrCo tritide的平衡压力。在两个反应温度和两个最终H / M比下，将各种氢气和氦气混合物应用于氢化反应，以确定氦气是否影响氢气分压的降低。不管进料气体中的氦气含量如何，在不同温度和最终H / M比条件下，残余氢气压力与ZrCo氢化物的平衡压力相似。通过循环回路进行ZrCo氢化反应，氦3纯化工艺可有效去除remove杂质，而不会产生覆盖效应。
