        Primary byproducts of coal carbonization and petroleum cracking (H₂, CO, CH₄, C₂H₄, etc.) are surveyed and their applications in NH₃ synthesis, hydrogenation, and the syntheses of MeOH and CH₂O are indicated.  CH₄ in turn may become a starting point for C₂H₂, HCN, MeCl, etc.; C₂H₄ for EtOH; and ethylene glycol for butadiene and synthetic rubber.
