Abstract

The measured thermobaric adsorption of anthracite coal “V_meas” contains 12 pairs of testing results at different temperatures (18∼72 °C) and corresponding pressures (1∼19 MPa), simulating the buried depth of 100∼1900 meter has been published by Zhang Qingling in 2008. A temperature-pressure-adsorption equation (TPAE) has been used to regress the measured data, then to calculate the 12 pairs of thermobaric adsorption data “V_cal”. The relative error and the standard deviation between the V_meas and the V_cal are calculated and used to verify TPAE's applicability for thermobaric adsorption data. The 3-dimensional TPAE surface is also used for verification. The other 3 sets of optimized thermobaric adsorptions (10 pairs, 8 pairs, and 6 pairs) have been created. To cover a range of temperature (18∼72 °C) and pressure (1∼19 MPa), there must be at least the minimum 6 pairs of thermobaric adsorptions including the lowest temperature 18 °C and pressure 1 MPa, and the highest temperature 72 °C and pressure 19 MPa.

煤炭热压吸附测试方法及其数据处理探讨

无烟煤的热压吸附实测数据 "Vmeas "包含 12 对在不同温度（18∼72 °C）和相应压力（1∼19 兆帕）下的测试结果，模拟埋深 100∼1900 米。利用温度-压力-吸附方程（TPAE）对测量数据进行回归，然后计算出 12 对热压吸附数据 "Vcal"。计算出 Vmeas 和 Vcal 之间的相对误差和标准偏差，用于验证 TPAE 对热压吸附数据的适用性。三维 TPAE 表面也用于验证。还创建了另外 3 组优化的热压吸附（10 对、8 对和 6 对）。为了覆盖一定的温度（18∼72 °C）和压力（1∼19 兆帕）范围，必须至少有 6 对热压吸附，包括最低温度 18 °C 和压力 1 兆帕，以及最高温度 72 °C 和压力 19 兆帕。
