摘要

Objective Up to 45％of total organic carbon(TOC)was probably lost during acid treatment in carbonate-rich rocks(Froelich,1980).Some scientists thought these acid-soluble organic matters were largely contributed from carboxylic acid salts,which were commonly developed in alkaline carbonate formations and could potentially be excellent sources for natural gas stored in Early Paleozoic carbonate rocks in the Ordos Basin(Chong and McKay,1984;Liu et al.,2017).However,the gas generation from carboxylic acid salts was not systemically studied.As reported in Liu et al.(2013),these carboxylic acid salts were dominated by calcium stearate and calcium palmitate.Thus,gold-tube closed pyrolysis using calcium stearate as reactant was conducted to investigate the gas potential of carboxylic acid salts.
