This book discusses effective and alternative uses for natural gas (NG) and highlights the utilization of NG in the field of methane activation and chemical production.  It details the techniques used during the reforming process of petrochemical and bio-derived fuels and it presents cutting-edge research that describes the utilization of NG that enables it to be more cost-effective and eliminate the expensive greenhouse gas emitting process of hydrogen production.  The book addresses three major topics: NG use in upstream heavy oil and bitumen upgrading, NG and its use in downstream oil refining through co-aromatization of various feeds in the petrochemical industry, and NG use in the upgrading of bio-derived fuels and discusses alternative uses of NG.  In-depth chapters demonstrate uses for NG beyond heating homes, through catalysis and in-situ hydrogen donation, and its potential applications for the petrochemical and biofuel industries.
