Abstract
Fuel gas mixts. comprises (a) 40-50 (pref. 42-47) mole % of methylacetylene and propadiene; (b) 35-45 (pref. 40-45) mole% of a C3 stabiliser with a positive heat of formation, comprising propane, propylene and/or cyclopropane; and (c) 8-18 mole % of a C4 stabiliser with a negative heat of formation, comprising butane, butene and/or butadiene. The gases are esp. useful for autogenous welding. They have a high overall heat of formation, which remains constant in the course of withdrawal from the storage tank, and are stable w.r.t. self-dissociation.
